2X BMS 4S Active Balancer Board 1.2A Lifepo4 Li-Ion Lithium Battery Transfer Equalizer Module Inductive Version

2X BMS 4S Active Balancer Board 1.2A Lifepo4 Li-Ion Lithium Battery Transfer Equalizer Module Inductive Version Description

This board is based the principle of adjacent equalization and cannot be used as a maintenance tool. To connect to the battery, it must be used with the lithium battery protection board.
Inductive working principle:This module is the adjacent voltage difference equalization, the adjacent battery voltage difference reaches more than 0.1V, the chip internal triggers the equalization work, until the adjacent battery voltage difference is within 0.03V and stops working
when it is used the battery pack, there is adjacent voltage difference when charging and discharging Triggering the equalization work, the battery pack voltage error will also be pulled back to an perfect value, reducing battery maintenance costs.

Wiring Definition:
B-: The total negative pole of the battery pack (the negative pole of the first battery)
B1: Positive pole of the first battery
B2: Positive pole of the second battery
B3: Positive pole of the third battery
B4: Positive pole of the fourth battery
B. . . . . . N+ and so
Technical Parameter:
1. Working voltage: 2.0V-4.5V
2. Universal ternary iron lithium battery
3. LTO battery is not applicable! ! !
Balance Instructions:
1. When the equalization light is , the equalization work is turned
2. The equalization light is off, and the equalization circuit is in sleep state
3. The equalization light flashes, indicating that the string is dropped, or the circuit is faulty.
Balance current:
1,The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A)
2,Adjacent voltage difference is more than 0.2V (maximum equilibrium current is 1.2A)
3,The smaller the voltage difference, the smaller the equalizing current.
