11. Stable charge and discharge performance
12. Wide temperature performance
13. Fast charging, about half an hour to be fully charged
14. Require no change to a lead acid battery charging system
15. No gasses during charge, free of leakage and pollution
16. Easy installation and carrying, can be carried and installed in any direction

Safety Assurance

Passed abuse and safety test such as drooping, nail penetration, short circuit, thermal shock, impact, crush, over charge, over discharge. and there is no fire and no explosion with stable chemical structure.

Battery care and maintenance

The cycle life of li-ion battery would be shorted if the battery alway be kept as fully charged state. For
long time storage, keep the battery as 40~60% state of charge (SOC) and discharge and charge every one or two
monthes.
• Battery should be kept under dry and ventilation condition. Do not put the battery close to fire and explosive

Applications

a. UPS backup

b. Mobility Devices

c. Solar energy Storage

d. Caravan and camping

e. Personal power packs

f. Medical Equipment

Storage Conditions

◆For long time storage ,the battery should be charged to Approx 60% SOC ,its corresponding voltage should be 1.05times of nominal voltage(24V,36V,60Vor72V),usually it's voltage in shipment .The battery should be kept in storage in dry and ventilated place.

◆ The battery pack and charger should be stored in clean, dry and ventilated place, avoid contacting with corrosive materials and be away from fire and heat.

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℃.
