Li-WATT 12.8V-200Ah

Feature of LiFePO4 Battery

• 
  
  Longer Cycle Life: Offers up to 10 times longer cycle life and 5 times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership
• 
  Lighter Weight: The weight is approximately 40% to 50% less than that of a lead acid battery. When compared to lead acid batteries, it can conserve space.
• 
  Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while maintain high energy capacity
• 
  Superior Safety: The chemistry of lithium iron phosphate avoids the possibility of explosion or combustion caused by heavy impact, overcharging, or short circuit circumstances.
• 
  Wider Temperature Range: -10℃~60℃
