  Features of LiFePO4 Battery  
     • Longer Cycle Life:Offers up to 20 times linger cycle life and fivetimes longer float/claendar
      life than lead acid battery, helping to minimize replacement cost and reduce total cost of
      ownership.

     • Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop in'
      replacement for lead acid batteries.

     • Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while
      maintaining high energy capacity.

     • Operating Temperature Range: -10℃~55℃
     • Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or
       combustion due to high impact, overcharging or short circuit situation.

     • Increased Flexibility: Modular design enables deployment of up to sixteen batteries in series
      and up to ten batteries in parallel.


 Application  
     • Electric Vehicles,electric mobility solar/wind energy storage system
     • UPS,backup power
     • Telecommunication
     • Medical equipment Lighting
     • And so on
