Rechargeable 3.7V 2500mAh Li-ion Battery Cell For Escooters

Rechargeable 3.7V 2500mAh Li-ion Battery Cell For Escooters

3.7V 2500mAh Li-ion Battery Cell almost the biggest capacity for  battery cell for 3C rechargeable one,

of course, which should fulfillment all marketing quality certification and  other requirements; 

For most seconds, the capacity for li-ion battery cell is not the big  problem, as all we know that

even the Samsung and LG Li-ion battery product aslo has the quality issues;

The only way to reduce the potential risk is strength the production standard and testing power.
