Advantages of battery:
Advantages of battery: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.
Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop
in' replacement for lead acid batteries.
Higher Power: Delivers twice power of lead acid battery, even high discharge
rate, while maintaining high energy capacity.
Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion
or combustion due to high impact, overcharging or short circuit
situation.
Increased Flexibility: Modular design enables deployment of up to four batteries in
series and up to ten batteries in parallel.
Wider Temperature Range: -20℃~60℃.
