BMS 3S (12.6V – 25A) Lithium Battery Protection Module with Balanced

Description3S 11.1V 25A 18650 Li-ion Lithium Battery BMS Protection PCB Board With Balance Function.Specification:Overvoltage range: 4.25 ~ 4.35v ± 0.05vOver-discharge voltage range: 2.3 ~ 3.0v±0.05vMaximum operating current: 0 ~ 25AMaximum transient current: 34 ~ 40AQuiescent current: less than 30uAInternal resistance: less than 100mWorking temperature: 40 50 CEffective life: more than 30000hShort circuit protection: Yes, delayed self-recoverySize: 56mm x 45mm x 1.2mm (LxWxH)Notes:Strictly according to the diagram wiring: 0V(B-) 3.7V(B1) 7.4V(B2) 11.1V(B ), Do not deliberately short circuit.After the wire is connected, it needs to charge the batteries first, then have output.When the battery is connected in series with 3 groups , please ensure that the voltage of each battery is the same. If not the same, please fill in each set of batteries and then use them.Do not mix the good battery and the battery.It will be better the capacity of the battery internal resistance is closer.
