Description:
Bottom Discharge 36V 15AH Mountain E Bike Lithium Ion Battery Pack With Samsung 18650 Cell YM109

Compared with the same capacity lead-acid battery, LiFePO4 battery is 1/3 smaller in size, 2/3 lighter in weight, 5 times longer in cycle life, more economic and eco-friendly.
Lithium battery replacing Lead acid battery is an inevitable trend.

Imported cells from Samsung, LG or Panasonic are all optional.

Or Cells from China domestic famous cell manufacturers are more cost-effective.
