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. 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℃~60℃.
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.
