Feature：

1. Active balance functionality, lose battery capacity no need to balance sales voltage difference, increase battery use efficiency for 95%

2. It has the protections of overcharging/overdischarging/overcurrent and short circuit, etc.

3. Single battery series voltage range is 1~5V, accuracy is 5mV

4. With coulomb meter function, the remaining power is very clear

5. BT communication function, battery status can be displayed on APP

6..JK BMS, they are smart therefore with bluetooth and are equipped with a built-in active balancer, this will allow you to always have balanced cells and battery with full capacity
