- Overcharge detection voltage: 4.28+ 0.05 V
- Overcharging voltage: 4.095-4.195V
- Over-discharge voltage: 2.55±0.08
- Overcharge detection delay time 0.1s
- Temperature range -30~80
- Short circuit detection delay time: 100ms
- Over-current detection delay time: 500 ms
- Balanced current: 60mA
- Working current: 30A
- Overcurrent: 60A
- Short circuit protection function: there is, disconnect the load can be self-recovery.
Overcharge protection, over-discharge protection function, short circuit protection function, over current protection function, balance.
- Strictly according to the diagram wiring: 0V(B-) 3.7V(B1) 7.4V(B2) 11.1V(B3) 14.8(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.
