Standard Battery Parameters
WHEN ADJUSTING YOUR X1 MINI CHARGING PARAMETERS, BE SURE
YOU SELECTTHE PROPER BATTERYTYPE AND CELLVOLTAGE FOR THETYPE
OF CELL YOU ARE CHARGING. CHARGING BATTERIES WITH THE WRONG
SETTINGS MAY CAUSETHE CELLS TO BURST, CATCH FIRE OR EXPLODE.
Charging
Before charging your batteries, it is critical that you determine the maximum
allowable charge rate for your batteries. The X1 mini is capable of charging
at high rates that may not be suitable or safe for your particular batteries. For
example, Lithium cells are typically safe to charge at 1C, or the total mAh÷1000.
A 1200mAh battery would have a 1C charge rate of 1.2 amps. A 4200mAh
battery would have a 1C charge rate of 4.2 amps. Some manufacturers are
oering Lithium cells that can be charged at greater than 1C but this should
ALWAYS be veried before charging a Lithium battery at rates higher than 1C.
Voltage is just as critical as the charging amperage rate and this is determined
by the number of cells in series, or“S”. For example, a 3S LiPo is rated at 11.1 volts
(“S”multiplied by a single LiPo cell with a nominal voltage of 3.7 volts DC. 3 cells
x 3.7 volts each equals 11.1 volts DC).
Connect the battery’s main leads to the charger output: red is positive and
black is negative. Keep in mind that the gauge or thickness of your charging
leads from the X1 mini to your battery must be of an acceptable current rating
to handle the applied charge current. For maximum safety and charging
eectiveness, always match or exceed the main battery lead rating when
assembling or selecting your charging leads. If you charge a battery at a high
current rate (amperage) with a charging lead not rated for the chosen amperage,
the wire could get hot, catch re, short out and/or potentially destroy your
battery and the charger.
Warning
When in doubt, always use a higher gauge wire (lower AWG number). It is
common to see charging leads constructed of 14AWG, 16AWG or 18AWG wire.
Always refer to recommendations from your battery manufacturer for your
specic battery type and size before initiating a charge or discharge process.
Do not attempt to disassemble or modify Lithium or Lead-Acid battery packs.
Discharging
The X1 mini discharging functions are for two specic purposes:
• Refreshing the capacity of a Nickel-based battery that has lost capacity over
time (NiMH or NiCd).
• Reducing the voltage of a Lithium battery for safe storage.
LITHIUM CHEMISTRY BATTERY PACKS SHOULD ONLY BE DISCHARGED
TO THEIR MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING
A LITHIUM CELL WILL DO PERMANENT DAMAGE. REFER TO THE
STANDARD BATTERY PARAMETERS TABLE ON PAGE 6 OF THIS MANUAL
FOR MINIMUM DISCHARGE VOLTAGES.
LiPo & LiHV Charge/Discharge Cycling
Lithium batteries are known to reach full capacity after a break-in period of
about 10 charge/discharge cycles. We do not recommend you use the X1 mini
charger to do this; normal use and recharging will achieve the same results.
If you wish to perform a Lithium break-in on the bench with the X1 mini,
discharging to minimum acceptable voltages and performing a balance charge
at 1C maximum rate is recommended. If you choose to break in your Lithium
batteries under normal use, charging at only 1C for the rst ten cycles will help
ensure full performance and service life from your Lithium cells.

Fast and Storage Mode of Lithium Battery:
Depending on your application requirements, you may choose fast charge or
storage mode. Fast charge reduces the amount of time required for charging,
whereas ‘store’ state controls the nal voltage of your battery.
Re-Peak Mode of NiMH/NiCd Battery:
In re-peak charge mode, the charger can peak charge the battery once, twice,
or three times in a row automatically. This function is useful for ensuring a full
battery charge.
Delta-Peak Sensitivity for NiMH/NiCd:
This automatic charge termination program is based on the principle of the
Delta-peak voltage detection. When the battery’s voltage exceeds the threshold,
the process will be terminated automatically.
Cyclic Charging/Discharging:
1 to 5 cyclic and continuous charge > discharge or discharge > charge sessions
are optimal for battery performance and balancing.
Automatic Charging Current Limit:
You can set the upper limit of the charging current when charging your NiMH
or NiCd battery. The ‘AUTO’ charging mode, however, is recommended when
charging NiMH batteries with low impedance and capacity.
Battery Meter:
The user can check the battery’s total voltage, the highest voltage, the lowest
voltage and the voltage of each cell. The user can also check the battery’s total
internal resistance and the internal resistance of each cell.
Capacity Limit:
The charging capacity is always calculated as the charging current multiplied by
time. If the charging capacity exceeds the limit, the process will automatically
terminate according to the maximum value previously set.
Temperature Threshold*:
The battery’s internal chemical reaction will cause the temperature of the
battery to rise. If the temperature limit is reached, the process will be terminated.
* This function is available by connecting an optional temperature probe which
is available as a separate purchase.
Processing Time Limit:
Protect your battery by setting a maximum time limit for charging and discharging.
Features Features [cont.]

Using the Charge Master PC Software
The free“Charge Master” software gives you unparalleled ability to operate the
charger through your PC computer. You can monitor pack voltage, cell voltage,
and other data during charging, view the charge data in real-time graphs, or
control charging and rmware updates from the “Charge Master.”
In order to connect the charger to a computer and enjoy the benets of the
“Charge Master” program, you will need a USB cable which is not included in this
package. The cable must have an “A” plug on one end and a “micro-B” plug on
the other to connect to the charger directly.
The “Charge Master” is available for download at www.hitecrcd.com.
Commonly Used Terms
Commonly Used Terms:
A, mA: Unit of measurement relating to a charge or discharge current. 1000 mA
= 1A (A = Ampere, mA = Milliampere).
Ah, mAh: Unit of measurement for the capacity of a battery (Amperes x Time
Unit; h = hour). If a pack is charged for one hour at a current of 2A, it has been
fed 2Ah of energy. It receives the same quantity of charge (2Ah) if it is charged
for 4 hours at 0.5A, or 15 minutes (=1/4 hour) at 8A.
‘C’ - Rating: Capacity is also referred to as the‘C’rating. Some battery suppliers
recommend charge and discharge currents based on the battery ‘C’ rating. A
battery’s‘1C’ current is the same number as the battery’s rated capacity number,
but noted in mA or amps. A 600mAh battery has a 1C current value of 600mA,
and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current value for a
3200mAh battery would be 3200mA (3.2A).
Final Charge Voltage: The voltage at which the battery’s charge limit (capacity
limit) is reached after which the charge process switches from a high current
to a low maintenance rate (trickle charge). From this point on, any further high
current charging would cause overheating and eventual terminal damage to the
pack.

Commonly Used Terms [cont.]
Final Charge Voltage: The voltage at which the battery’s charge limit (capacity
limit) is reached after which the charge process switches from a high current
to a low maintenance rate (trickle charge). From this point on, any further high
current charging would cause overheating and eventual terminal damage to the
pack.
Final Discharge Voltage: The voltage at which the battery’s
discharge limit it reached. The chemical composition of the batteries determines
the level of this voltage. Below this voltage, the battery enters deep discharge
zone. Individual cells within the pack may become reverse polarized under these
conditions, resulting in permanent damage.
Nominal Voltage (V): The nominal voltage of the battery pack can be
determined as follows:
- NiCd or NiMH: Multiply the total number of cells in the pack by 1.2. An 8-cell
pack will have a nominal voltage of 9.6 volts (8 x 1.2).
- LiPo: Multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in
series will have a nominal voltage of 11.1 volts (3 x 3.7).
4-cell LiHV wired in a series will have a nominal voltage of 14.8 volts. (4 x 3.7).
- Lilo: Multiply the total number of cells in the pack by 3.6. A 2-cell Lilo wired in a
series will have a nominal voltage of 7.2 volts (2 x 3.6).
- LiFe: Multiply the total number of cells in the pack by 3.3. A 4-cell LiFe wired in
a series will have a nominal voltage of 13.2 volts. (4 x3.3).
- LiHV: Multiply the total number of cells in the pack by 3.7. A 4-cell LiHV wired in
a series will have a nominal voltage of 14.8 volts. (4 x 3.7).
If the nominal voltage of the battery is not printed on
the battery’s label, consult your battery manufacturer
or supplier. Do not attempt to guess the rated voltage
of the battery.
