LiFePO4 Lithium Solar Batteries / 48V 40Ah Solar Energy Storage Batteries 2500 Cycle Life
LiFePO4 48V 40Ah Solar Energy Storage Batteries For Home Backup Battery , 2500 Cycle Life
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.

Battery Handling Precautions
◆ Don’t immerse battery in water or allow it to get wet!
◆ Don’t charge, use and store battery near a heat source such as fire heater! If the battery leaks or releases strange odor, please remove it from place near fire place immediately. Fully charge the battery before first-time using.
◆ Don’t reverse the positive and negative pole of battery!
◆ Don’t throw the battery into fire or heat it!
◆ Don’t short-circuit battery with wire or other metal objects!
◆ Don’t nail, knock or trample the 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.
