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

Description

3S 11.1V 25A 18650 Li-ion Lithium Battery BMS Protection PCB Board With Balance Function. Specification: Overvoltage range: 4.25 ~ 4.35v ± 0.05v Over-discharge voltage range: 2.3 ~ 3.0v±0.05v Maximum operating current: 0 ~ 25A Maximum transient current: 34 ~ 40A Quiescent current: less than 30uA Internal resistance: less than 100m Working temperature: 40 +50 C Effective life: more than 30000h Short circuit protection: Yes, delayed self-recovery Size: 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.
