3.If a set of batteries with over-discharge and over-charge cells, the bms cannot be charge and discharge.

2. Connect the battery  will happen cannot  discharge status, in this case, connect the charge can be restored to normal working state; 

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;

Notice:

5) low standby current consumption.

4) MOS transistor can control the battery charge and discharge;

3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);

2) terminal of the charger using high voltage device;

1) high-accuracy voltage detection circuit;
