Quality and Guarantee
A) Power management: You may be completely confident in our lithium batteries because all batteries have built in high quality PCB board, charging protectors, thermal protectors and circuit breakers, which effectively avoid the problems of over discharge, ove charge, over heating and short circuit etc.
B) Our lithium batteries follows the ISO9001, CE, RoHS international standard in various aspects from material preparation to production, quality control, sales, transportation, customers service.
C) Safety test, after nail penetration test with fully charging, there is no fire, no explosion.
Product Advantages
- High energy density.
- High integration and small installation space.
- Long cycle life.
- No heavy metal, environmental protection.
- Full internal BMS protection, high voltage battery protection, higher reliability.
- Cell construction features minimize impact from extreme internal heat and pressure.
- Ultra safe, each battery module comes with an integrated battery management system (BMS).
Key Features
- Longer cycle life: 20 times longer cycle life and 5 times longer float life compared to lead-acid batteries.
- Lighter weight: about 40% of the same kind of lead-acid battery weight.
- Higher power: offer two times of the lead-acid battery power, and even high discharge rate, while maintaining high energy capacity
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
Application
Transportation, grid power, and commercial and industrial vehicle markets, stationary energy storage.

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℃.
