key features

1、Accurate capacity measurement: apply intelligent capacity IC survey meter to calculate the residual capacity. The precision is up to 15%.

2、Multiple protective functions: overcharging, over-discharging, overcurrent, short circuit, etc.

3、Ultrasonic welding makes exquisite appearance. The product can fall from 1.2m height and won’t damage.
