48V 12Ah Panasonic downtube power lithium battery pack with 30A continuous working current  via 13S4P by NCR18650-PF 2900mah cells. (2 years warranty included)

Internal Dimension: 310*78*73mm
External Dimension
External size: 361*90*92mm
Recommended to install the electric core number: 50 or 52pcs 18650 cells 

1. Instruction of the Battery Pack Structure
(1) Battery modules
52 cells, 4 parallel and 13 serial to make a battery module
50 cells, 5 parallel and 10 serial to make a battery module

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
(3)Charge/discharge standards for cell
 Cell adopted:  18650 2200mAh-3400mAh cells
 Constant charge current: 0.2 C 2A -2A is the best charging current, single cell max voltage<4.3V
 Constant discharge current: 15-30A is the best discharging current, single cell min voltage> 2.75V
 Rapid charge capability: Max charging current 0.5C.
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.
