5A Capacitor Active Equalizer Balancer Board for LiFePO4/NCM/Li-ion Packs (3S-21S) with Cable

OverviewThis 5A capacitor active equalizer balancer is designed for LFP LiFePO4, NCM, and Li-ion battery packs to help equalize cell voltages across series-connected cells.Key Features Capacitor active equalization Equalizing current: 5A Battery chemistries: LFP LiFePO4 / NCM / Li-ion Supported Battery Pack Configurations (Series Cells) 3S 3~4S 4~5S 4~6S 5~7S 6~8S 9~14S 12~16S 13~17S 17~21S Safety Information 1. Buyers need to have a certain level of electronic knowledge and relevant hands-on ability. 2. Before connecting the circuit board bus plug, make sure to check each wire connection is correct. The insulation between the base plate and the battery connection terminal is required to prevent burning. 3. Each circuit board undergoes strict quality testing. If the circuit board is burned due to incorrect operation, the buyer will be responsible.

The color of each wire has no special meaning. Please solder the wires in the order of B- to B1, B2, B3. It is prohibited to insert the bus into the circuit board until all the wires are soldered and checked without errors. 2. Pay attention to the B- wire connecting to the total negative pole of the battery pack, B1 wire connecting to the positive pole of the 1st battery, B2 wire connecting to the positive pole of the 2nd battery, B3 wire connecting to the positive pole of the 3rd battery, and so on (follow the correct wiring diagram/connections). 3. Please note that the number of batteries in your battery pack must match the number of batteries supported by the balance board. For example, for a 6S-8S, only connect 6, 7, or 8 batteries. 4. If you purchased a 6S-8S balance board but only connect 6 batteries, connect all 6 batteries following the rule above. The remaining B7 and B8 wires must be insulated and do not need to be connected. 5. Before connecting the balance board bus plug, make sure to check each wire connection is correct. The insulation between the base plate and the battery connection terminal is required to prevent burning.
