1.Instruction of the Battery Pack Structure

(1)Battery modules

40  cells,  4 parallel and  10 serial to make a battery module.
(2)Protective board

The protective board, provides protection against overcharge, and short circuit, through monitoring

single string of cells. Also it enables every battery pack to obtain independent balancing function

(3)Charge/discharge standards for cell

 Cell adopted:  ICR3.7V2200mAh-2900mAh 

 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.

2.Storage and Transportation

(1)Based on the characters of cells, proper environment for transportation of battery pack need to be created to protect the battery.

(2)During transportation,50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.

(3)Battery should be kept at -20ºC~45ºC in warehouse where it is dry, clean and well-ventilated.

(4)During loading of battery, attention must be paid against dropping, turning over and serious 

stacking.

 

3. Warnings and Tips

In order to prevent the battery leaking, getting hot and exploding, please pay attention to preventing

measure as following:

 Never throw the battery into water, keep it under dry, shady and cool circumstance when not use.

 Never upside down the positive and negative.

 Never connect the positive and negative of battery with metal.

 Never ship or store the battery together with metal

 Never knock, throw or trample the battery.

 Never cut through the battery with nail or other edge tool.

    Notices! 

 Never use or keep the battery under the high temperature. Otherwise it will cause battery heat, get into fire or lose some function and reduce the life. The proposed temperature for long-term storage is 10-45ºC.
