The large capacity 12v battery apply with high-quality 4s lifepo4 battery prismatic cells, the battery system come with built in BMS and relay protections. Total energy 12kWh. Each battery module weight 30KG. Total system weight 120Kg.
The 12v lithium ion battery structure.
The Large 12v 1000ah lithium ion battery system build by 4s lifepo4 prismatic battery cells. Each unit cell capacity is 50Ah. Total 1000Ah based on 12.8 volt on system. It can effectively charge and discharge the battery pack by PV or ongrid AC by invertor . Heavy duty load 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 pack system 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 1000 amp hours 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.
- Over-charge test
- Over-discharge test
- Short-circuit test
- High-temperature test
- Fire test
- Squezzing test
- Pin-Prick test
- Fall down test
- Water immersion test
- Shooting test
- OEM orders are available and looking for long term distributors/dealers.
- Coremax 12v 1000ah lithium ion battery provide Superior quality and cost-performance ratio
- If the battery system takes high drain discharge current( over 300amps). We suggest 48v battery system. With 16S nominal voltage 51.2volt. This is most regular system for home energy storage. And easy to compitable with any invertors.
