Product Description

48V electric bike battery rear rack battery case

30Amps high performance blade type discharge fuse
6Pins discharging plug with nickel-plating
Waterproof grade: IP65
52PCS 18650 Cylinder cells, capacity 36V11Ah-17Ah or 48V8.8AH-13.6AH
DC2.1 charging Port (optional 5Pin high current charging Plug)
1.Instruction of the Battery Pack Structure
(1)Battery modules
50 cells,5 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 
 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.
