Main features:
1. Longer Cycle Life: offers up to 20times longer cycle life and five times longer float /calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership
2. Lighter Weight: about 40% of the weight of a comparable lead acid battery, 'drop in' replacement for lead acid batteries
3. Higher power: delivers twice power of lead acid battery ,even high discharge rate, while maintaining high energy capacity
4. Wider temperature range: -20 to 60°C
5. Superior safety: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situation
6. Increased flexibility: modular design enables deployment of up to four batteries in series and up to ten battery in parallel
