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

Please charge the battery timely after kept for more than 2 monthes so that the battery cycle life would be much
longer. 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
products. When charging the battery, cut of the load.
• The best working environment of our lifepo4 battery is 15 ~ 40 °C, please take some necessary procedures, like
heating & cooling system, or use heat insulation materials to stop cold effect battery in winter.
• When the temperature is more than 75°C (Internal temperature of the battery), the battery cycle life would be
shorted. So do not exposure the battery under the sun during summer.
• When the temperature is under -20°C or lower, the battery performance would be effect and the mileage might
be shorted.
• Do not wash the battery shell with organic solvent. If there’s fire accident, please do not use CO2 to extinguish
the fire but use CCl4 or sand soil.

Applications of 12.8V 12Ah li ion battery
The energy storage battery is applicable for commercial or residential purposes:

1. Solar Energy Storage
2. Solar Street Lighting
3. Light Electric Vehicle
4. E-Bike/E-Rickshaw

6. UPS

Advantages of 12 volt lithium battery 66Ah:

• Green product: LiFePO4 material is no harm to enviroment and human beings, it's environment friendly and no pollution.
• Long Cycle life: More than 2000 cycle times and up to 5 years serve life.
• Very safe: It have the best safety and steady performance, no fire, no exploding under the condition of over-charge.
• Light weight and smaller dimension: The dimension compares with other battery, about 1/2-2/3 weight of lead acid.
• Great capacity and more powerful,rechargeable battery: We can install many single cells in series and in parallet and it can fully discharge.
• No memory effect: It can be recharged anytime,no reduction of the capacity.

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.
