Rechargeable 18650 Lithium Battery Cell

Rechargeable 18650  Lithium Battery Cell 

Rechargeable 18650  Lithium Battery Cell is the basic units of battery pack and battery pack is the

core heart of electric scooter;

This is not general 18650 Battery Cell which the max discharge current can reach 3C and it means 3 times of the max charge rate;

Our own cooperated partner supported all supply chain management of the rechargeable battery cell with 500 cycles  times' life.
