Applications:
1S lifepo4 Rechargeable batteries
Notice:
1. Please pay attention to the use condition of input and output voltage and load current , make the protective plate within the power consumption of no more than specification allows power consumption;
2. Connect the battery will happen cannot discharge status, in this case, connect the charge can be restored to normal working state;
3.If a set of batteries with over-discharge and over-charge cells, the bms cannot be charge and discharge.
