Description
Model LC10S15ADC-MC, for use with LiPo, Li-Ion, A123, NiCd, NiMH, and Pb battery packs
10s Multi-Chemistry, 15 Amp, 600W model for automatic and manual charging with available high-power
balancing, overcharge protection, and automatic charge/discharge to storage (for Li batteries)
Features

Charges Lithium Polymer, Lithium Ion, A123, NiCd, NiMH, and Pb packs. Charges any brand of
pack.
Supports high-power balance charging of Li or A123 battery packs. Balance charges one 1s to 10s
pack, or two 1s to 5s LiPo packs simultaneously. When two packs are connected, the balance
connections and pack main discharge wires are wired in series by the charger.
Equipped with Cellpro brand (JST PA series times two, 6 position) balance connectors which enable
the charger to monitor and independently charge each cell to its optimum level (balance charge
operation).
Accepts Cellpro 10s Adapters for plug-and-play compatibility. Cellpro 10s Adapters support from 2s
to 6s battery packs (all brands). For more information on REVO adapters, visit
http://www.revolectrix.com/cellpro_adapters.htm
Backward-compatibility with older Cellpro 4s adapters is assured using the available 6-pin to 5-pin
adapter(s) (REVO PN: CP10S-5S/4S-ADP-US) for charging 2s to 4s Cellpro packs having 5-pin
balance connectors.
Also supports customer-selectable, XH mode. JST XH/EH balance connectors and wiring are
growing to be the dominant scheme in the industry. Switching to XH mode, the CP10XP can support
existing XH style adapters you may already own. Splice in REVO PN: CPBP6P-10-US battery
pigtails to the wires on existing adapters and you are good to go!
Supports non-balanced charge of Li (up to 2s), Ni (up to 28 cells), Pb (up to 24V), A123 (up to 12s).
Accepts 10-32 VDC input.
Up to 15A max charge current.
Maximum 25A input current
720W max continuous input and 605W max continuous output at 30V DC input. Charger will achieve
rated output to a 10s LiPo using 30V DC input. Increasing input voltage beyond 30V does increase
power output, but only if the charger’s output voltage exceeds 42V; e.g., when charging 12s non-
balanced A123 packs. However, 32V DC input is a maximum rating. It is recommended to utilize
input voltage slightly below the absolute maximum.
Supports AUTO rate charging (1.0C, 2.0C, and 3.0C charge rate) using Advanced Fuel Gauging
technology, or manual set currents of 0.10A –15A in 0.10A increments.
Industry’s largest 1A proportional integrated balancers
Power-balance-charge packs through balance connectors in tandem with the main discharge wires of
the battery pack(s). Unit does not support balance-connector only charging.
Compensates for balance wire lengths up to six feet with 1mV accuracy.
Displays individual cell internal resistance to 0.1milliohm, for estimating pack quality, health, and
performance.
Storage Preset available to charge or discharge Li batteries to appropriate per-cell storage levels; 3.8v
(LiPo), 3.0v (A123).

4
During discharge to storage, the CP10XP incorporates 1A-per-cell (nominal) discharge rate using the
charger’s integrated balancing circuitry to provide up to 42W (at 10s) discharge power.
Light-grey, 2 line, 16 character backlit LCD display provides easy readability.
One button, Charge Optimization can be set for an Accurate 1mV cell balance and (C/20 termination)
or for Faster Charging (less balancing accuracy and C/10 termination) using the Charge Control
Software or at the CP10XP interface.
Protects your Pb input source from over-discharge by providing an audible warning when input
voltage of your Pb battery approaches 50% state of charge.
Intelligent controller performs extensive checks to prevent damage to packs and power supply. This
makes it virtually impossible to damage the charger or the batteries from incorrect connections or
wiring; including, but not limited to reverse polarity.
Input reverse-polarity protection.
Simple, effective, 2-button interface allows instant access to presets, preset parameters, and starting
and stopping charger operations.
Access pre-defined, named presets by clicking the MODE button.
Hold the MODE button to access the Main Menu operations: Choose Chg. Amps, Choose Chemistry,
Show Help Screen, Exit. Use the charger’s Main Menu to alter basic settings of presets on-the-fly, or
make the adjustments using the free PC Charge Control Software (CCS).
Press and hold the START/STOP button to start charger operation or cancel/end a charging session.
Press and hold MODE button during power up to access Options Menu; choose input amps limit and
supply low voltage setting (Power Management feature), alternate between FMA or XH balance
wiring schemes, and set quiet charging (no speaker beeps during charging).
Supports Bi-directional, optional PC interface (REVO PN: FUIM2-US or FUIM3-US) which enables
extensive charger setup using the CCS. Configure up to 10 custom presets, adjust speaker volume,
set LCD contrast and control many other settings.
CCS automatically checks for software and charger firmware updates in the background. Update
charger firmware reliably with the click of your mouse button, and without sending the charger back
to the factory. Keep up-to-date with the latest enhancements and bug fixes.
6 different, available Fuel Gauge lookup tables (fuel tables) may be assigned to independent presets
to match the characteristics of different Li battery chemistries. This feature only available using the
CCS.
Works with a wide range of power supplies, even those not rated for high power. Easily changes
from moderate current bench supply at home to car battery at the field using the Power Management
feature. Set Input supply amps limit and supply low voltage settings using the CCS or at the charger
interface, to prevent damage to your input source.

Understanding the Cellpro 10XP Charger
Auto Charging vs. Manual Current Settings
When balance charging Li batteries, you can set the Cellpro 10XP Charger’s charge rate to one of three
AUTO modes—1.0C, 2.0C or 3.0C—as appropriate for the pack(s) being charged. When one of these
rates is selected, the charger determines the pack’s capacity (over time) and automatically sets the
correct output current using FMA’s advanced Fuel Gauging technology. The accuracy of AUTO
charging depends on how well your battery’s charge curve matches up with the fuel table being used by
the CP10XP. Six different fuel tables are available to support different Li battery chemistries and may
be assigned to individual presets using the Charge Control software. Factory presets for LiPo batteries
are set up for a generic, 15C battery profile. AUTO charging using the default presets may or may not
be accurate for your batteries. The advantage to using AUTO charging is that you do not need to think
about or even know the true capacity of your batteries. You can charge different capacity batteries at
different times without having to adjust the charge rate setting and the charge will automatically adjust
to choose the appropriate charge rate. You just tell the CP10XP how fast you want to charge, and it
does the work for you. For safety reasons, AUTO charging current is capped at 6A, regardless of the
size of the pack being charged. You can also manually set charge current to any value between 0.1A
and 15A in 0.1A increments. Finally, you can select Storage Charge mode which automatically charges
or discharges to the appropriate per-cell storage voltage for LiPo or A123 batteries.

Input Voltage (VDC)
Power (Watts)
Continuous Input (Watts) Continuous Output (Watts)
When one pack is connected to the charger, the pack is initially charged at the selected charge rate (or
the maximum charge rate possible). Using Ohm’s law, the maximum charge rate (Amps) is derived
from the maximum power (Watts) the charger can produce without overheating.
Maximum output power will normally reach approximately 605W when charging a 10s LiPo battery
using a 30V DC input power source, and assuming the input source can deliver a maximum of 720W of

10
clean power to the charger input. Maximum power depends on many factors including pack imbalance
during charge, input (supply) voltage, output (charge) voltage, DC/DC converter efficiency, which
varies between 80% and 95% depending on the relationship of supply voltage-to-charge voltage,
ambient temperature, and internal operating temperature. From the graph, you can see that Increasing
input voltage beyond 30V does increase power output, but only if the charger’s output voltage exceeds
42V; e.g., when charging 12s non-balanced A123 packs. However, 32V DC input is a maximum rating.
It is recommended to utilize input voltage slightly below the absolute maximum.
When the pack reaches about 95% capacity, the charger enters balance charge mode. Charge current
tapers off, but will remain at 1A or higher until the pack voltage slows the current to 1/20th C (Constant
Voltage Mode). When the pack reaches 99% capacity, the charger beeps three times. The pack can be
removed to use, or allowed to continue charging until it is 100% full and the charger displays “Charge
Complete.”
During the entire charge process, the charger power balances the pack using 1A current until all cell
voltages are within 1mV of each other. Power balancing is the process of beginning the balancing
process early in the charge cycle using high-current shunts to drain excess cell voltage while other cells
in the pack have a chance to catch up. Power balancing means the pack tops off faster and the total
charge time is greatly reduced. This is possible because the balance circuitry is internal to the charger.
Automatic temperature control and an integral fan ensure the charger never exceeds maximum safe
operating temperature under any conditions. The result is faster, safer charging.
When charging two packs, the packs are connected in series (the balance connections as well as the
main charge wires). In effect, the charger treats the two packs as a single pack. For example, if you
connect a 3s pack and a 4s pack, the charger operates on them as one 7s pack. If the pack capacities are
different for the two packs connected, the charge rate should be selected based on the lower capacity
pack. Initially, the packs are charged at the selected charge rate (or the maximum charge rate possible)
until one pack becomes fully charged—however, the charger can handle cell balancing of the two packs
completely independently. The second pack continues to charge at a minimum 1A rate until it is full
and balanced.
Notice that one of the packs in a simultaneously-charged pair is always topped off at a minimum rate of
1A (dictated by the maximum balance current available). If the packs have the same capacity, and were
discharged to about the same level, both packs will charge in less than 30 minutes at 3C. However, if
the packs have different capacities, or were discharged to different levels, charging for the pair could take
longer than expected. Since the charger supports a high power balance current of 1A, all other things
being equal, the charger still outperforms competing brands. In most instances, by the time the first pack
is fully charged, the second pack is already approaching constant voltage charge mode; the battery pack
itself is the limiting factor in charge time, not the charger.
Example 1: You are powering an aircraft with two 4s 2100mAh packs connected in series.
Because those packs have the same capacity, and were discharged to about the same level
during flight, you can expect them to charge in about the same time. It would be appropriate
to charge them simultaneously using the Cellpro 10XP Charger.
Example 2: You are powering one aircraft with a 3s 500mAh pack, and other aircraft with a
5s 5000mAh pack. If you charge these packs simultaneously using the Cellpro 10XP Charger,
it would probably take a long time (the 500mAh pack would become full first, then the
charger would switch to its 1A balancing rate to fill up the 5000mAh pack, which could take
several hours). In this case, it would be faster to charge these packs separately because the
charger can then apply optimum (and substantially different) charge currents to each pack.
In some cases, such as Example 2, it will be faster to charge two packs separately rather than
simultaneously. It’s up to you to decide, based on what you know about their respective capacities and
discharge states.

11
In Example 2 above, when the 500 mAh pack reaches 99% capacity (the charger beeps three times), it is
a simple matter to remove the pack from the charger and continue charging the 5000 mAh pack at a
higher charge rate. Here’s how:
1. Connect both packs and start charging them using an AUTO or manual rate setting.
2. Watch the fuel level display. When one pack reaches 99% fuel level, stop charging.
3. Disconnect the full pack.
4. If the partially charged pack is connected to Channel 2, move it to Channel 1.
5. Continue charging the partially-charged pack.
About Factory Presets
During all phases of the charge process, the charger will balance all the cells in Channel 1 and Channel 2
together as one big pack, and report the fuel level of two packs being charged as one big pack. The
exception to this is if you use one of the Factory presets (or set up a custom preset) containing the words
“Dual Channels”. In this case, the CP10XP will balance all the cells in Channel 1 against each other and
all the cells in Channel 2 against each other, and report the fuel level of the two packs independently.
Power Management Feature
The charger will draw up to 25A to deliver its 15A maximum output current. The high input current is
required when the input voltage must be boosted to drive packs having larger numbers of cells in series.
Output power is determined by several factors, including battery pack imbalance during charge, input
voltage, input current, output voltage, ambient temperature, and the charger’s internal temperature.
The charger’s DC-to-DC converter is typically 80% to 95% efficient. Highest efficiency occurs when
the input voltage is higher than the output voltage needed to charge the connected pack(s). However,
the charger cannot tolerate input higher than 32V DC. Supplying input voltage of 30V provides the
highest efficiency, coolest operating temperature and fastest charging times, especially when charging
packs containing more than five cells in series.
You can also manually limit the charger’s input current and adjust the supply low voltage limit so the
charger will not draw more power than the supply can provide. If you know your power supply is rated
for 3A output, for example, you can limit the charger’s input current to 3A. (Be aware that limiting
charger input current may increase pack charge times.) If you are using a Pb battery to power the
CP10XP and you do not want to discharge below a certain voltage, you can set it where you want it.
When the charger is powered from a high current source (such as a car battery), you can adjust the
current limiting to provide maximum pack charging current. Details for changing these settings are
provided in sections “Options Menu Explained” as well as “Limiting charger input current” under
“Using the Charge Control Software”. The Factory Default settings for the Power Management feature
are as follows:
1. Input Supply Current Limit: 25A
2. Input Supply Low Voltage Limit: 11V

12
Connecting packs to the charger
General information
When balance charging, both a balance connector and the main discharge wires must be connected to
the Cellpro 10XP.
When performing a non-balance charge on a 2s Li, A123, NiCd, NiMH, or Pb pack, connect only the
pack’s main discharge wires to the two outer banana jacks on the charger’s front panel.
When charging only one pack, always plug that pack’s balance connector into the charger’s Channel
1 balance port and always connect the main discharge wires to the charger’s outermost banana jacks.
When charging two packs simultaneously, make sure to correlate each pack’s balance connector and
pack discharge leads to the same charger Channel. For example, first pack’s balance connector in
Channel 1 balance port, first pack’s discharge leads to Channel 1 banana jacks (the left two jacks).
Second pack’s balance connector in Channel 2 balance port, second pack’s discharge leads to
Channel 2 banana jacks (the right two jacks).
When charging two packs, both packs must have the same chemistry. For example, you can’t charge
one A123 pack and one LiPo pack at the same time. Never mix chemistries under any circumstances.
After a charge is initiated, never alter the connections between the charger and the battery packs.
Always end the current charge session before making any connection changes. See page 21 for more
information about STARTING and STOPPING charge sessions.
WARNING: Failure to comply with the above could result in fire and/or damage not covered by warranty!
Pack discharge wires are usually not terminated in banana plugs (e.g., they might be terminated in a
Deans connector). For convenience in connecting to the charger, prepare an adapter cable with
banana plugs on the charger end and a connector that mates with the pack’s discharge connector on
the other end. Revolectrix sells banana plugs suitable for this purpose as REVO PN: CP10S-BP12-
2PK-US, Cellpro 10s Banana Plug Output Cables (2 pack).
CAUTION: When using the banana plug adapter cables described above, ALWAYS insert the banana
plugs into the charger BEFORE connecting the adapter cable to the pack. Reverse the sequence when
disconnecting the pack. This will prevent the live banana plugs from touching each other, which would
create a dangerous condition and could seriously damage the pack.
Connecting non-Cellpro packs
Generally, follow the instructions in “Connecting one 1s to 10s Cellpro pack” and “Connecting two 1s
to 5s Cellpro packs” below, but your packs may not be equipped with compatible balance connectors.
REVOLECTRIX offers plug-and-play adapters for charging LiPo packs equipped with balance
connectors made by other manufacturers. Check http://www.revolectrix.com/cellpro_adapters.htm for
adapter compatibility. The Cellpro 10XP Charger works with all existing Cellpro 4s charger adapters.
You must connect a 6-pin to 5-pin Adapter (REVO PN: CP10S-5S/4S-ADP-US) between the charger
and the Cellpro 4s charger adapter, as shown here:
If an adapter isn’t available for the pack you want to charge, or if the pack doesn’t have a balance
connector, the REVOLEXTRIX PN CPBP7-US (Cellpro battery pigtail 10”, 5 position) and/or PN
CPBP6P-10 (Cellpro battery pigtail 10”, 6 position) cable assemblies can be used to make the pack
compatible with the Cellpro 10XP Charger. Instructions for connecting these cable assemblies to your
packs are provided in the “Cellpro Pin Lead Connection” document at:
http://www.revolectrix.com/support_docs/item_1315.pdf
Note: see also “Balance connector wiring” later in this manual.

13
Connecting one 1s to 10s REVOLECTRIX Cellpro pack
1. How you connect the Cellpro pack’s balance connector(s) to the charger depends on the pack’s
configuration. Use the photos in the section “Pack terminology and configurations” above, then find
the configurations in the diagrams below and connect as shown in that diagram.
2. When charging a single pack, plug the discharge wires into the outermost banana jacks.
Connecting two 1s to 5s Cellpro packs
1. How you connect the Cellpro packs’ balance connectors to the charger depends on the packs’
configurations. Use the photos in the section “Pack terminology and configurations” above, then find
the configurations in the diagrams below and connect as shown in that diagram.

14
2. When charging two packs simultaneously, connect the discharge wires into the banana jacks as shown
below.

15
Applying power to the charger
To apply power to the charger: Connect the charger to a 10V to 32V DC power supply, field battery
or car battery. If your bench power supply is equipped with banana jacks for output, you can remove
the plier clips from the charger’s input cables and plug the cables directly into the power supply jacks.
When the charger is powered up, it displays the following “Welcome” screen:

the charge settings for a preset at the charger (as described in “Changing a preset,” later in this manual),
those changes are retained when the charger is disconnected from power, and will be reapplied when the
charger is powered up again.

16
“Selecting a preset” and “Changing a preset,” in the next section, provide additional information.
Note: If you programmed the charger using the Charge Control Software, different presets may be
available. Also, if you have been using the software, you may have given the factory presets different
names. Bottom line: if you change settings at the charger, or redefine presets, you probably won’t see the
factory presets shown above. To revert back to the original factory settings above, initiate a Factory
Restore using the CCS, Presets tab.
Operating the charger
You operate the charger using the MODE button and START/STOP button on the right side of the
charger. This simple, effective, 2-button interface allows instant access to presets, preset parameters, as
well as starting and stopping charger operations.
MODE button: enables you to view/select a preset, change preset parameters and display charging
data during charging.
START/STOP button: enables you to start charging after you have selected a preset, and to stop or
cancel a charging session at any time. The START/STOP button also allows you to toggle back and
forth between Accurate and Faster Charge optimizations (applicable to LiPo and A123 battery packs
only).
Overview of button operations:
Following is an overview of all possible functions available using these buttons. These functions are
listed in the approximate order you might use to traverse the CP10XP.
At start up, press the MODE button to access and scroll the Preset Menu and to view/select pre-
defined, named presets and their settings, one at a time. A preset is considered “selected” when its
name and settings are listed on the charger’s LCD.
At any time prior to starting a charge operation, press and hold the MODE button to access the
Main Menu options: Choose Chg. Amps, Choose Chemistry, Show Help Screen, Exit.
While watching the scrolling menu options, continue holding the MODE button, then, release it
only when you see the menu option you want. Now you may use the charger’s menu to alter
parameters of presets on-the-fly. Note: Preset parameters are permanently saved the instant they are
changed.
When inside of Main Menu options, press the MODE button to change preset parameters.
When changes to preset parameters are complete, press and hold the MODE button to access the
Main Menu again. Then choose Exit to return to the Preset Menu.
Press the START/STOP button to toggle back and forth between Accurate vs Faster Charge
optimization. This feature available only when a LiPo or A123 balanced preset is selected.
Press and hold the START/STOP button (for 1 second) to start charger operation or cancel/end a
charging session.
At any time while charge is in progress, press the MODE button to view real-time operating
information and charging data.
Special Button Operation:
Press and hold MODE button while applying power to access and scroll the Options menu: CHOOSE
SPLY AMPS, LOWS SUPPLY VOLTS, NODE CONNECTOR, QUIET CHARGING, Exit. Use the Options
Menu to choose input amps limit and supply low voltage setting (Power Management feature),

alternate between FMA or XH balance wiring schemes, and set quiet charging (no speaker beeps
during charging).
Performing Common Tasks:
Selecting a preset
At start up, press the MODE button to access and to scroll the Preset Menu and view/select pre-
defined, named presets and their settings, one at a time.
The preset displayed when you stop pressing the MODE button is the “selected” preset. Once the preset
is selected, you can change the parameters for this preset (see “Changing a preset”) or begin charging by
pressing and holding the START/STOP button (for one second).
Note: The Charge Control Software enables you define up to ten custom presets. Using the CCS, you
can change the names of the Factory Presets, or change any of the available parameters associated with
each preset. If you have defined custom presets, you can—at the charger—select any preset. (If you
have not defined custom presets, the factory presets are available.)
Changing a preset
You can change the charge parameters for the currently selected preset to match the characteristics of
the pack(s) you are charging.
At any time prior to starting a charge operation, press and hold the MODE button to access the
Main Menu options: Choose Chg. Amps, Choose Chemistry, Show Help Screen, Exit.
While watching the scrolling menu options, continue holding the MODE button, then, release it
only when you see the menu option you want. Now you may use the charger’s menu to alter
parameters of presets on-the-fly. Note: Preset parameters are permanently saved the instant they are

To Quick Start a Charge (Exit the Main Menu and begin charging in one operation if a pack is
connected): Press and hold the START/STOP button for one second. Details are provided in the
next section.
Charging a pack or packs
1. Before charging, pack(s) must be properly connected to the charger. See “Connecting packs to the
charger,” earlier in this manual for details. Also, the correct preset must be selected for the packs
connected to the charger. See “Selecting a preset”, earlier in this manual for details.
2. Press and hold the START/STOP button for one second to enter Charging Mode.
3. You will see the following screens in sequence:
PLEASE WAIT…
