Six Protection Functions of the BMS

1. Charging Protection

Seiko IC effectively controls MOS to prevent battery overcharge and battery explosion

2. Discharge protection

Prevent battery power from dying and affect the life of lithium batteries

3. Over current protection

Prevent the battery from being damaged by excessive instantaneous current

4. Short circuit protection

Automatic protection during abnormal short circuit to prevent battery

5. Temperature protection

The NTC temperature control probe is added to prevent the damage caused by spnta-neous combustion of the battery when the temperature is too high.

6. Drop protection

When the cable is off, then the BMS has no output.
