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
Applications for LiFePO4 Battery 12V:
· Energy Storage Systems (ESS)
· Hybrid Grid back-up
· Remote area power systems
· Communications systems
· Electric vehicles
· Marine environments
· Military & Aviation
· Industrial Machinery
· Uninterruptible Power Supplies
· CCTV & Data Transfer
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.
Wider Temperature Range: -20 C~60 C.
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.
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.
