BMS 3S (12.6V - 40A) Lithium Battery Protection Module (Enhanced Version)

Description

3S 40A BMS 11.1V 12.6V 18650 lithium battery protection Board for drill 40A currentSpecification:Overvoltage range: 4.25 ~ 4.35v ± 0.05vOver-discharge voltage range: 2.9 ~ 3.3v±0.05vMaximum operating current: 0 ~ 40AOvercurrent protection current: 70 ~ 90AQuiescent current: less than 24uAWorking temperature: -40 +85 CShort circuit protection: Yes, delayed self-recoverySize: 60mm x 41mm x 1.2mm (LxWxH)Notes:Strictly according to the diagram wiring, 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.+
