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.Better cells ensure good consistance of battery pack, we are doing now !!
Quality belong to high level, it is can't be douted.
Order process is simple, no need to wait manager, deputy manager, product manager ...etc to sign to agree our order.
