Main features:
1. Longer cycle life: offers up to 20 times 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 weight of comparable lead acid battery, A 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-ion phosphate chemistry eliminates 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
