Lithium battery 12v 20ah for solar

Lithium battery 12v 20ah for solar 

Product feature

1.this battery suitable for all of the electric vehicle and skiing borad and UPS backup. 

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

Small dimension and light weight
3.The Li-ion battery is have half dimension and third weight compare with the lead-acid battery. Thus the performance of the whole EV is improved and the battery can be taken off easily.

 Green battery to protect environment
4.The lead-acid battery will pollute the environment seriously because of frequent replace, but the Li-ion battery is green power without pollution.

 Very safe and Reliable
5.The Li-ion battery is more safe and reliable than the lead acid one. It wont explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat.

Rapid charge
6.The battery can be full charged in2 hours at 0.5c current.

banlance charge and discharge
7.The pack have a BMS, so it will not over-discharge and over-charge. It is as a balance charger, but it is cheaper than it.
