Product Description
LiFePO4 Battery for energy Storage

Features of LiFePO4 battery
1) 100% safe. It's the ONLY 100% safe battery among all lithium batteries.
2) Super long life cycle ( charged & discharged for 2000 times under 80% DOD ).
3) Absolutely environmentally friendly, no pollution at all, no heavy metal, no rare metal, no toxic, ISO9001 / CE / UL / RoHS Certificate granted.
4) Light in weigh, 1/3 of lead acid battery.
5) Smaller in size, 2/3 of leads acid battery.
6) High voltage for signal cell (3.2V / cell).
7) High Discharge Rate Capability: 3C continuous / 5-8C burst, can stand the highest discharge current.
8) Quick charging ability (2C quick charging to 85% within half an hour)
9) High temperature endurance, can work normally from -20oC to 70 oC and can endure 500oC environmental temperature.
10) Low self-discharge rate, < 3% /month.
11) No memory effect.

We offer LiFePO4 battery cell from 5AH to 300AH with most advanced technology. We also supply battery pack, battery management system (BMS) and charger as a complete solution. Due to strong production capacity and mature technology, our price is very competitive.
Any battery pack we produced were assembled by series and parallels of single battery cells ,So you can also  buy single battery cells , and DIY according to your demands.
