Applications

1. Power system: LiFePO4 batteries can be used as backup power supply or energy storage system to provide reliable power support for the power system and ensure continuous power supply in case of power failure or power shortage.

2. Solar energy storage system: Used in combination with solar energy systems, LiFePO4 batteries can store the electricity generated by solar power generation and release it when needed to achieve sustainable energy use.

3. Uninterruptible power supply (UPS) : provides power guarantee for computers, servers and other devices to ensure that they can continue to run when the power is interrupted.

4. Golf carts: Golf carts need to be able to continuously drive long distances, and the high energy density and long life of LiFePO4 batteries can meet this demand.

5. Toys and power tools: These devices often require high power and long-lasting power support, and the high energy density and long life of LiFePO4 batteries make them ideal choices.

6.RV application: As the main power supply, stable power supply for RV equipment, emergency power supply, but also portable power for outdoor activities, and high safety.

7.Fishing boat application: Provide boat power and equipment electricity, emergency backup, with environmental protection, in line with the green concept.
