Battery Active Equalizer 1A 10S Lithium Ion/Lifepo4 Battery Cell Balancer BMS 10S For E-Bike
Inductive energy transfer equalization board, high current 1.0A energy transfer battery voltage balancer, significantly balance battery voltage, improves the overall efficiency of the battery pack!
Balance indication:
When the equalization light is on, the equalization work is turned on.
The equalization light goes out, the equalization circuit sleeps,
The equalization light flashes, the string indication is lost, or the circuit is faulty.
There are two different types of Battery equalizers
Balancing is the process of equalizing the voltage and state of charge (SOC) of each cell in a battery pack. This prevents overcharging or undercharging of individual cells,
which can cause damage, reduce capacity, and shorten lifespan. Balancing can be done either during charging (top balancing) or during discharging (bottom balancing).
Top balancing is the most common method for LiFePO4 cells, as it ensures that all cells are fully charged to their maximum capacity. Top balancing can also prevent over-discharging of cells during use, as they will have more reserve capacity at the lower end of their voltage range.

Wiring definition
B-,the total negative pole of the battery pack(the negative pole of the first battery).
B1, the positive electrode of the first battery.
B2, the positive electrode of the second battery.
B3..... and so on.
Direction for use
①The first, terminal wire is soldered to the battery pack.Next,Connect the terminal wire to the PCBA.
(2)13 or more string plugs need to be inserted obliquely,first touch the B-pins and insert them obliquely upwards,otherwise it may cause the board to burn out.
