1. High dimension ration power: 32650-5.5Ah weight ratio power:121Wh/Kg, dimension ratio power 312Wh/L

2. Long cycle and service term: 1C charge/discharge,100% discharge depth,80% capacity after 2000 times charge/discharge cycles.

8 years service term on EV.

3. Good safety performance: no explosion and burning after safety testing like over charging/discharging, short-circuit, dropping, squeezing, heating, penetrating.

4.Good performance at high or low temperature: 105%capacity can be released when charge and discharge at 55°C; 80% capacity can be released when discharge and discharge at -20°C.

5. Samll self-discharge current: rest for one month with half SOC, self-discharge current less that 3%.

6. High efficiency of charging: capacity efficiency (ampere hour efficiency) usually 100%, 100Ah for charging and 100Ah for discharging.

7. Good performance of heavy current: the capacity stays the same with 100% capacity when the batteries discharge at different rate at 0.1C~5C.
