Compared with lead-acid batteries:

1、More environmentally friendly (no heavy metal pollution)

2、Small size (20% smaller)

3、Can hold more power (same weight, 2.5 times more power)

4、Longer service life (cycle life increased by 3 times)

5、More stringent protection (temperature protection, overcharge protection, over-discharge protection, short circuit protection, balanced voltage, maintenance-free)
