Product Description
Production Advantage
1, High energy density, could reach 460-600Wh/kg, 6-7 times base on Lead acid battery
2, Long lifespan, could reach to 6-12 years. Lithium iron phosphate as positive, battery 1C(100% DOD)charge & discharge have record use 10000 times.
3, High Rated voltage (Cell work voltage 3.2V/3.7V), Approximately equal to 3pcs Ni-Cd or Ni-MH rechargeable batteries work in series.
4, Have high power Endurance, electric car use Lithium iron phosphate battery could reach to 15-30C charge and discharge capacity. Easy for high strength start auto acceleration.
5, Low self-discharge current. This is lithium battery one of the most prominent advantages. Usually could be 1% per month. Less than 1/20 of Ni-Mh.
6, Light weight. Same volume the weight around 1/6-1/5 of lead acid battery
7, Adapt to high temperature, could work in -20℃--60℃ environment, after processing can work under -45℃.
8, Environment protecting,during production, using and scrap,.do not produce any lead ,Hg, cadmium and any others Toxic and harmful heavy metal elements and substances.
9, No need any water during production, for lack of water country is very helpful.
