Custom 12v lithium ion Battery Manufacturer in China
Consisting of three li-ion cells (3S) or four lifepo4 cells(4S) in series, 12V lithium ion battery actually a very general term with 11.1V nominal voltage of li ion battery or 12.6V nominal voltage of lifepo4 battery. If you want lightweight and high energy density, 3S lithium ion 12v battery is ideal and widely used in portable power, ekectric scooter, roboics. If you want safety and long cycle life, 4S batterie ion lithium 12v is suitable and commonly used in solar lighting, energy storage systems, UPS backup, marine and RV power systems.

Each cell is automatically sorted in voltage,internal resistance and capacity to minimum tolerance to ensure stable performance of total pack. To make low resistance and well connection,the nickel strips are spot-welded onto the terminal. The BMS insulation paper, fiberglass sheets and heat-shrink are strictly applied to consolidate the structure. Each pack is strictly tested in voltage,charging &discharging test, BMS function verification.
Key Feature of 12v lithium ion battery

All the 12v lithium battery pack uses cell holders internally to place the cells, which can not only ensure solid constructure, but also ensure good insulation between each cell.
Yellow exposy boards and blue plastive sheet shrink are applied to each side of the li ion battery pack to ensure complete insulation and solid structure.

VTCBATT 12v lithium battery pack passed CE, ROHS, MSDS, IEC62133, KC, CB, UN38.3
certification, which can not only help you save certification cost, but also make your product more competitive in the global markets and win customers’ trust and confidence.

12v lithium battery pack can be designed in different size, capacity and current to satisfy different applications. No matter whether you need ultra slim shape ,round shape or stick shape,we can all produced exactly as your specific requirements.
Solar lighting and Solar systemBatterie lithium ion 12v 100ah is widely used in solar lighting and solar system to replace the normal lead acid battery.Featuring ultra long cycle life,the battery has 6000+ cycle life and 10 years shelf life.
RV& Marine applicationRV&Marine is the most popular application for 12v lithium ion battery 100ah.
The battery is maintenance-free and can reach up to 6000+ cycles with 80% capacity retention.
It can always provide stable and strong power for the RV&marine.
Portable DeviceFeaturing high energy density,small 12v lithium ion battery are ideal for portable devices,such as handheld industrial tools,outdoor&camping gear,robotics&drones.No matter whether you need
12v 50ah, 12v 10ah or 12v 12ah lithium ion battery,VTCBATT can design exactly as per your demand.
A: First,you need to identify whether it is 3S lithium ion battery or 4S lifepo4 battery.Their fully charge voltage is totally different. 3S 12v lithium ion battery charger should stop charging at 12.6V voltage.4S 12v lithium ion battery charger should cut off at 14.6V.You need to use specific 3S or 4S 12v lithium ion battery charger without mixing.
A:12v lithium ion battery consists of three li-ion cells (3S) or four lifepo4 cells(4S) in series,which are both normally referred as 12V.
A: Only professional electrical technicians are allowed to make 12v lithium ion battery.
First,you need to sort the cells used in the battery pack and design the battery configuration.
Second,Spot weld the nickel strip on the cells after the battery pack is configured correctly.
Third,apply the insulation paper,fiberglass and heat shrink to consolidate the structure.
Fourth, test the battery voltage,charging &discharging test, BMS function verification.
A: It’s dangerous to charge the 12v lithium ion battery without the correct charger, which may cause fire, explosion.
