LiFePO4 Cell Advantages:
Long cycle life 4500 remain above 80%, low self discharge, much safe LiFePO4, passed punching test. Excellent Temperature resilience-ambient temperatures up to 50°C will not affect the life. High Discharge Current,1C is standard, higher currents are also acceptable up to 3C continuous with negligible loss in efficiency and cell life. Lighter and smaller than lead acid battery.
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.
Transportation & Storage of Li-ion Battery Pack
1) Can be transported via Truck, train, airplane and vessel, but to keep out of the sun & raining during transportation.
2) To handle the battery pack with care during assembling or dis-assembling, do not arbitrarily throw to avoid collision.
3) Do not place any heavy objects on the battery pack during transportation, to avoid crushing or damage caused.4) Do not mix Battery with flamm able, explosive, and sharp metal objects in transportation.
4) Make sure that the Packaging marked with moisture-proof & waterproof sticker, anti-fire stickers, to avoid dangerous in transportation.

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℃.
