Safety Test
No fire, no explosion
Charing to 3.7v and do nail penetration test, there is no fire, no explosion, no any other obvious changes.
Nail Penetration Test and Overcharge Test
After testing, no fire and no explosion, that is definitely approved than our lithium batteries deserve you.
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
LiFePO4 is best-choice of materials in commercial Lithium batteries for large capacity, high power and safe strict applications, such as Home solar energy storage, power tools, wheel chairs, e-bikes, e-cars and e-buses, solar storage system etc.
LLife 4500 cycles, more than 80%. Large overcharge tolerance and safer performance. Self balance. Four times higher energy density than Lead-acid battery. High temperature performance.
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℃.
