Instruction of the Battery Pack Structure
(1)Battery modules
78 cells, 6 parallel and 13 serial to make a battery module.

(2)Protective board
The protective board, provides protection against overcharge, and short circuit, through monitoringsingle string of cells. Also it enables every battery pack to obtain independent balancing function

(3)Charge/discharge standards for cell
Cell adopted: ICR3.7V2200mAh
Constant charge current: 0.2 C5A -1 C3A is the best. cell max voltage<4.3V.
Constant discharge current: single cell min voltage> 2.75V
Rapid charge capability: Max. charge current1C3A;temperature increase falls within 15°C is
normal while over 15°C will affect the cycle life of cell.
