52V 40Ah Rechargeable Lithium Ion Battery Pack 21700 4.5Ah Cell Customized
52V 40Ah Rechargeable Lithium Ion Battery Pack 21700 4.5Ah Cell
18650 Li-ion batteries are the battery of choice when designing for higher voltage and current requirements. Li-ion have relatively low self-discharge rates, and are capable of high discharge currents and better performance than nickel and lead based batteries.
Customized battery pack service are warm welcome, which is one of our best advantages.
Battery cell can be choose for China brands or LG SAMSUNG SONY PANASONIC
BMS parameter could change based on application
Design battery size and solution in free service
Buyer advise connector type in order to assembly accordingly.
VODNO provide specification of battery and help to get certification.
