Battery structure.

The battery pack build by 3S lithium ion battery with built in PCM/BMS. can effectively charge and discharge the battery pack . The BMS prevent any battery overcharge, over discharge caused by damage, And can control the battery charge, discharge current,Ensure that the battery pack and applications are not damaged;To ensure that in the event of a short circuit failure when the output off and automatic balance of the application of the battery pack at any time in the best condition. Design with ON/OFF switch. Easy to operation without plug the battery connector.  12v 20000mah li ion battery packed with blue PVC. This PVC Provide basic protection from any physical damage.

Safety and economical

12v 20000mah lithium ion battery with Newest 3.7v Lithium polymer cells. Battery cell is tested before assemble. It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons it’s safe for household use.

Excellent discharge characteristics

li ion battery 12v 20ah With low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field. Like UPS/Solar System/CCTV System/ camera

Long cycle life

lithium 12v 20ah battery Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.
