EZ-PEAK PLUS LITHIUM CHARGE MODES
When charging lithium batteries, the EZ-Peak Plus allows the user to
select from three different charge modes: Standard Charge, Balance
Charge, and Fast Charge. All the modes are “fast” in that they charge
the battery quickly, but each mode offers certain benefits.
Before selecting a charge mode, be certain to input the correct
lithium battery type:
Selecting the Lithium Battery Type
1. Press the STOP key until the display
reads USER SET PROGRAM.
2. Press the ENTER/START key to
advance to the next screen (V-Type)
3. Press the ENTER/START key.
The voltage value will flash.
Use the +/- keys to select 3.3V/LiFE, 3.7V/LiPo, or 3.6V/LiIo.
4. Press the ENTER/START key to input the new setting.
Standard Charge (CHARGE)
The standard charging mode allows the EZ-Peak Plus to charge lithium
batteries without requiring the balance adapter. This mode will support
the balance adapter if connected, but it is not necessary. Standard
Charge uses the Constant Current/Constant voltage charging method
to deliver maximum capacity. Only charge and discharge lithium
batteries using the included balance adapter.
Balance Charge (BALANCE)
The Balance Charge mode uses the Constant Current/Constant
voltage charging method to deliver maximum capacity, and requires
the balance adapter to be connected to the battery and charger. The
Balance Charge mode monitors the voltage of each individual cell, and
charges each cell to equal voltage. Balance Charging is the best way to
charge lithium batteries, and Traxxas strongly recommends always using
the Balance Charge mode with all lithium packs that have a balance
connector. If the balance adapter is not used in Balance Mode, the EZ-
Peak Plus will begin charging but stop after a moment, sound an alarm,
and display BATTERY VOL ERR CELL CONNECT. If your battery is not
equipped with a balance plug, use the CHARGE or FAST CHG modes.
Fast Charge (FAST CHG)
The Fast Charge mode modifies the Constant Current/Constant Voltage
charging process to allow the fastest possible charge time. Final charge
capacity will be slightly less than the charge capacity achieved with the
Standard Charge and Balance Charge modes, but total charging time
will be reduced. The Fast Charge mode will support the balance adapter
if connected, but it is not necessary. Only charge and discharge
lithium batteries using the included balance adapter.
Storage (STORAGE)
For maximum performance and life, it is recommended that Lithium
batteries be stored at 50-60% capacity if your Lithium batteries will not
be used within 30 days or more. The EZ-Peak Plus makes it easy to store
your packs properly with the STORAGE mode, which will automatically
charge or discharge the battery to achieve the correct storage capacity.
The storage mode will function with or without the balance adapter.
Only charge and discharge lithium batteries using the included
balance adapter.

12 •EZ-PEAK PLUS
Many of the EZ-Peak Plus’ settings can be customized to suit your
charging and discharging preferences.
Battery Check Time
The EZ-Peak Plus automatically detects the number of cells in a Lithium
pack as it charges to prevent accidental mis-setting of the number of
cells. However, a deeply discharged battery may cause the charger to
read a lower number of cells than the value correctly input by the user.
To prevent the charge or discharge cycle from ending prematurely
due to the charger not detecting the correct number of cells, you may
program the amount of time the charger will delay displaying a Voltage
Selection Error (VOL SELECT ER) message and automatically ceasing
the charge or discharge cycle. The default setting is 10 minutes, but the
time may be increased for high capacity (over 10,000mAh) batteries. To
prevent accidental battery damage, Traxxas strongly recommends
using the default time of 10 minutes or less.
To change the battery check time, follow these steps:
1. Press the STOP key until the display
reads USER SET PROGRAM.
2. Press the ENTER/START key to
advance to the next screen (V-Type)
3. Press the STATUS/+ key to advance
to the CHK Time screen.
4. Press the ENTER/START key.
The time value will flash.
5. Press the +/- keys to change the value. The minimum value is 5
minutes, the maximum is 60 minutes. To prevent accidental battery
damage, Traxxas strongly recommends using the default time of 10
minutes or less. Press the ENTER/START key to input the new setting.
NiMH and NiCd Delta Peak Sensitivity
While charging a NiMH or NiCd battery, the EZ-Peak Plus monitors the
voltage of the pack to determine when it is fully charged. When a NiCd
or NiMH battery is charging, its voltage will increase as it reaches a
peak (at which point the pack is fully charged), then begins to fall. The
EZ-Peak Plus detects this change in voltage and automatically stops
charging when the pack is fully charged (delta is the Greek sign for
change, hence the term “delta peak”). The amount of voltage change
the EZ-Peak Plus must detect to indicate a full charge can be changed
to help prevent the charger from incorrectly indicating a full charge
if the Delta Peak Sensitivity is set to low, or overcharging the pack if
the sensitivity is too high. The settings can be made independently for
NiMH packs (default is 7mV) and NiCd packs (default 12mv). To prevent
overcharging, raise the Delta Peak Sensitivity in small increments, and
only if required. If the battery is warm to the touch( 120F/52C ) when
the EZ-Peak Plus completes the charge cycle, the battery is receiving a
full charge and no adjustment to Delta Peak Sensitivity is needed.
To change the Delta Peak Sensitivity, follow these steps:
1. Press the STOP key until the display
reads USER SET PROGRAM.
2. Press the ENTER/START key to advance
to the next screen (V-Type).
3. Press the STATUS/+ key twice to
advance to the NiMH Sensitivity
screen, or three times to advance to
the NiCd Sensitivity screen. Use the
STATUS/- key to go back if you pass
the screen.
