1. Battery Application

The battery can be used in EV,HEV, UPS and Energy energy storage.

2. Battery Features

A. Long Life Time

The cycle life of the battery pack can reach 2000 times with 0.2C-1C discharge current.

B. Small Dimension and Light Weight

The Li-ion battery has half dimension and third weight of lead-acid battery. The battery can be taken off easily.

C. Green and Environmental Protection

Lead-acid battery will pollute the environment seriously because of frequent replace, but the Li-ion battery is green power without pollution.

D. High Safety and Reliability

Li-ion battery is safer and more reliable than lead acid battery. It won‘t explode or burn when bumping, stressing heavily, needle pricking, short circuit, overcharging and overheating.

E. Rapid Charge

The battery can be fully charged in 2 hours at 0.5C charge current rate.

F. Balance Charge and Discharge

The pack has a BMS, so it will not be over-discharged and over-charged. It is as a balance charger, but it is cheaper than it.

G. Wide Range Temperature

Li-ion battery can work under higher temperature compared with lead acid battery.
Charge Temperature 0ºC-45ºC
Discharge Temperature -20ºC-65ºC
Storage Temperature -20ºC-45ºC
