Safety&protection advantage:

• Built in Automatic Battery Protection System Internal

The intelligent,electric Battery Management System(BMS) protects lithium-ion batteries from extrem temperatures,overcharging,and excessive discharge,short circuit protection,balance voltage each cell.

• Automatic Over Voltage Protection : 58.4V 

Advantages of lithium batteries:

1. Life expectancy is two times that of lead-acid batteries. The weight is more lighter.
2. No memory effect and rechargeable. the battery life is more longer.

3. Green environmental protection, regardless of production, use and scrap, does not contain or produce any toxic and harmful heavy metal elements and substances.
4. Built-in BMS will prevent battery pack over charge, over discharge, over-current, over-heat, short circuit .
5. The self-discharge rate is very low, which is one of the most outstanding advantages of the battery. Generally, it can be less than 1%/month, less than 1/20 of the Ni-MH battery.
