3S / 4S Lithium Cell Balancer Module

Description

The 3S / 4S Lithium Cell Balancer Module Equipped with VH3.96 terminal by default, come with 1.31ft 18awg wire.

NOTE : This active balancer is not a BMS protection board, so no matter how bad the battery you use to test, it can be used, But it has no functions such as over-voltage, under-voltage, or over-current.
A BMS is required to manage all those things. Suggest use it in parallel with the BMS protection board.

Tips: This balancer board is backward compatible by default. If it is used for 3S, the last line B4+ is empty.

Note:
1. Please start wiring from the total negative pole, followed by B-, B1+, … B4+.(Test per string battery voltage whether is right before connecting to Balancer board).
2. The time required for equalization mainly depends on the battery capacity.

Capacitor energy transfer balance board with Balance cable (upgraded version, 5mv high precision, whole group balance, not adjacent balance)

Technical Parameters:
Working voltage: 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4).

Working principle: Flycap-capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB, balance current 0-5.5A, the more balanced the battery current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv!
The quiescent current is about 9mA, and the battery capacity is recommended to be used between 30-200AH/Per Balancer.

With under-voltage sleep protection, only detecting the battery voltage of B1, the equalizer will automatically stop entering the sleep state when the B1 voltage is lower than 2.7V, and the standby power consumption is <0.1mA.

Board size: 66x46x16mm/2.6×1.8×0.63inch
Balance cable length: 400mm/15.7inch
One LED indicator: It will always be on during normal operation, but it will not turn on when there is a problem or malfunction.
RUN pad: you can add a switch to control the balancer. Default short connect, let balancer working. if disconnect, it will not working.
