12v 300ah lifepo4 lithium ion phosphate battery packs for solar system
Description of LiFePO4 Battery
1. More than 3000 cycles time and 2 years long guarantee time.
2. More rechargeable time, longer life time, economic and environmental protection.
3. Light weight and portable.
4. LIFEPO4 material more safe.
5. Inbuit BMS multiple security protection.
6. APP control monitoring.
7. Charging Heating and low temperature till -20℃.
LiFePO4 technology offers high-powered cell performance compatible with lots of lithium-ion application to deliver more power and extend long life. Also built with bluetooth function allow you to read battery status freely anytime.
To relieve winter range anxiety in some freezing environment, the BMS can bring with self-heating function. Resistance heating rapidly warms the inside of battery. Start heating temperature:≤0°C. Stop heating temperature:≥10°C. Can improve battery charge / discharge performance.

Do not open the LiFePO4 battery without consulting the dealer. Unauthorized opening of the battery voids the manufacturer's warranty.
▪ Only use the battery for the application for which it is intended.
▪ Do not short-circuit the LiFePO4 battery. The cable connections to the consumers must go through a backup to be protected.
▪ Installation and maintenance may only be carried out by qualified specialists.
▪ Do not expose to permanent direct sunlight. Protect from the effects of heat. Temperatures above +60 ° C can damage the battery.
▪ Use only compatible chargers. The battery is in a longer storage of all disconnect devices.
▪ Pay attention to proper assembly.
▪ Avoid damage of any kind, for example by falling, drilling, etc. (Risk of short circuit).
▪ Always keep the battery dry and clean.
▪ Note the plus (+) and minus (-) markings on the LiFePO4 battery and the device and pay attention to the correct polarity.
▪ The cycle capacity may vary due to the change in the working temperature and the charge and discharge rate differ from the nominal capacity.
▪ Suitable for parallel connection maximum four batteries (If need series connection, the BMS should be customized with higher cost).
Before connecting, bring to the same charge level. Batteries from different manufacturers or different types should not be interconnected.
Storage and transportation
The battery must be packed and protected well during transport.
The lithium battery must be transported according to the rules for transport, these should always be followed (transportation code UN3480/UN38.3).
Never lift the battery by the terminals, only by the handles.
The battery should be stored in temperatures from -10℃ to +30℃. During transport, the battery should be about 50-60% charged.
The battery should be charged every three months to keep it active so that it always works maximum.
Warning & Tips
1. Keep the battery against high temperature. Otherwise it will cause battery heat, get into fire or lose some functions and reduce the life;
2. When the battery run out of power, please charge it within 15 days；
3. Please use the original or recommended charger for this battery;
4. If the battery leaks and get into the eyes or skin, do not wipe, instead, rinse it with clean water and see doctor immediately;
