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
- Higher Power: Delivers twice power of lead acid battery,even high discharge rate,while maintain high energy capacity
- High depth of DOD: Charge & discharge at 100% DOD with high performance
- No Memory Effect: Support unstable partial state of charge (UPSOC) (charge/discharge) utilization
- Built-in safety mechanism to protect assets against any abnormal conditions (Grounding damage, surge, deep drain etc.)
