Specifications

About 12v 1000ah lithium ion battery

The large capacity 12v battery apply with high-quality 4s lifepo4 battery cells, the battery system come with built in BMS and relay protections. Total energy 12kWh.

large 12v lithium ion battery structure.
The 12v 1000ah lithium ion battery system build by 4s lifepo4 prismatic battery cells. Each unit cell capacity is 50Ah. It come with can effectively charge and discharge the battery pack . large lithium battery 12v 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. The large capacity 12v lifepo4 battery also come with solid metal casing. Provide strong protection from any physical damage.

Safety and economical

12v 1000ah lithium ion battery does not explode or catch fire like lithium cobalt (found in cell phones and laptops etc). 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

large 12v lithium ion battery With low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field. Like 12v solar power system, Lithium RV battery packs, 12v lithium ion marine battery or any other backup power systems.

Long cycle life

large capacity 12v 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.
