48V lithium battery pack 48V Rear rack type lithium battery rechargeable e-bike battery 48v ebike battery pack

Features
Model: 48V 20Ah rear rack lithium-ion battery
Cell: 18650 3.7V 2500mAh cell.
Configuration: 13S8P
Nominal Voltage: 48V
Nominal Capacity: 20Ah
Size: 82*150*360mm (H*W*L)
Net Weight: Approx 7kg 
BMS: Custom BMS with 40A continuous discharging current and 120A peak current. 
Customization: 36/48V 10-30Ah rear rack type battery pack are all available to us with different cells.

BMS
The BMS provides protection against overcharge, and short circuit, through monitoring
single string of cells. Also it enables every battery pack to obtain independent balancing function.
 
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.
