1. How to Choose Best Cells ?

Firstly we will choose the cells with 10 MV gap on Voltage, 20 MAH gap on Capacity.

Internal resistance gap should be controlled within 3 MΩ that would be best choice for us.When Chinese battery cells is cycled for 800 times, there is 80% power left in battery cells. And imported cells have better performance than Chinese Cells. So this is our lowest testing standards.

2. What is the difference between li ion battery,NI-MH battery and Lead acid battery?

 Ebike Li-ion battery have longer cycle life,normal cyclelife is 600-800times, and also with light weight, small size, No memory effect, Nontoxic, environmental friendly.
