asic Performance:

(1) Output with high efficiency: Standard discharge current is 0.3C-0.8C, instant impulse discharge current is 10C for 10 seconds.

 

(2) Good performance under high temperature, it could work under 65°C temperature.The battery structure is safe and good.

 

(3) Good performance under low temperature.discharge capacity decreases to over 78% under 0°C and discharge capacity decreases to over 70% under -20°C.

 

(4) Good safety performance:When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion.

 

(5) Good cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell(80%DOD).

 

(6)  It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.

 

(7)  Low cost.

 

(8)  No pollution during manufacture and usage.
