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.
