LiPo Battery Cell Voltage Meter and Balancer Instructions
WARNING: FIRE HAZARD!
The Traxxas LiPo Battery Cell Voltage Meter and Balancer can
only be used with Lithium Polymer (LiPo) battery packs up to
6 cells. It is not designed to function with batteries of other cell sizes
and types. Before use, read and follow all manufacturer’s instructions,
warnings, and precautions. In addition, LiPo batteries pose a SEVERE
risk of fire if not properly handled per the instructions and require
special care and handling procedures for long life and safe operation.
LiPo batteries are intended only for advanced users that are educated
on the risks associated with LiPo battery use. Traxxas does not
recommend that anyone under the age of 14 use or handle LiPo battery
packs without the supervision of a knowledgeable and responsible
adult. Dispose of used batteries according to the instructions.
Important Warnings:
• This device has a balancing function intended for field use only. Use a
Traxxas iD charger for balancing with greater than a 0.5 volts difference
in cell voltage.
• Connect the battery to the device as instructed to prevent damage to
the device and/or the battery.
• Do not expose the device to water or moisture.
• Remove flammable items and combustible materials from the area.
• Do not pinch the battery wires, which may cause the battery to short
circuit and create the risk of fire.
• To preserve battery charge, do not leave the device connected to a
battery for more than 3 hours.
• Always disconnect the battery pack from the device when not in use.

Thank you for purchasing the Traxxas LiPo Battery Cell Voltage Meter and
Balancer. The Traxxas LiPo Battery Cell Voltage Meter and Balancer is a very
sophisticated electronic device that is controlled by a high performance
microprocessor and precise resistors. Please read the entire instructions
completely and attentively for important safety information and proper use of
the device.
Important Precautions
During the balance process, the voltage of each cell may change from time
to time due to the battery itself, the ambient temperature, etc. The remaining
capacity (Battery Capacity Gauge) display is based on voltage at no load. Since
it may differ largely from actual remaining capacity, use it as a reference only.
For safety, the device will enter sleep mode (SLP) after 3 hours even if the cell
voltages of the LiPo battery pack are not balanced. To protect the battery from
being over-discharged, there are minimum cell voltages to be balanced. If any
individual cell voltage is lower than 3.2 volts, the balance operation will not
start; if any individual cell voltage is lower than 2.8 volts, the error message (Err)
will be displayed on the LCD screen.
Operation
There are two basic functions of the Traxxas LiPo Battery Cell Voltage Meter and
Balancer:
1. Voltage Meter
This function can check the voltage of each cell of a Lithium Polymer (LiPo)
battery pack and display the remaining capacity in percentage (%).
Covers Part #2968, 2968X
2. Voltage Balancer
This function can equalize the individual voltages of each cell to their lowest
one. Balance operation automatically starts about 5 seconds after the battery
pack is connected to the device. When the voltage difference between cells
is over 0.02 volts, the balancer will start to work. The corresponding ”V”
will blink when it is balancing. When the voltage difference between cells
reaches 0.01 volts or less, balance operation ends and the device enters the
sleep mode (SLP will be displayed on the LCD screen). Note: This function
is intended for field use only. Use a Traxxas iD charger for balancing with
greater than a 0.5 volts difference in cell voltage. To preserve battery charge,
do not leave the device connected to a battery for more than 3 hours.
Simply connect the battery’s balance plug to the battery connector (7 pins;
XH type). Note: The negative lead or pin of the balance plug should match the
“Negative” indicator ( ) on the casing of the Traxxas LiPo Battery Cell Voltage
Meter and Balancer.
After the LiPo battery is connected, the LCD screen will display the voltage
of each cell and the built-in balancer will check the voltage. If the pack is not
balanced, the balancer will start working automatically.
Use the Traxxas iD LiPo balance adapter (part #2938X) to connect Traxxas
iD LiPo batteries to the battery connector on the device.
