3S 20A 12V Lithium Battery Charger Protection Board Module 18650 Li-ion Battery Cell Charging BMS

Note 1: in accordance with the diagram wiring 0 V, 3.7 V (B -) (B1) (B2), 11.1 V, 7.4 V (B +), don’t deliberately short circuit!

Note 2: after connected line need to recharge, just can have output.

Note 3:3 series battery, please make sure that each set of battery voltage, if not, please separate with each set of batteries in series. Discharge test, the battery voltage drops quickly is a bad battery.

Note: don’t put the good cells and in bad!Three groups of battery capacity/internal resistance as close as possible!(2 + 1 good battery, the use effect of poor battery = the use effect of three bad battery).
