Advantages of LiFePO4:

advantages of HB12400 wholesale LiFePO4 battery

LiFePO4, aluminum shell power battery

The safety performance of LiFePO4 aluminum shell power battery is one of the most advantageous materials at present. Using LiFePO4 aluminum shell power battery, there is no need to worry about the danger of electric explosion; coupled with the specification of the product's metal body, more effective protection The dangers of the battery itself

LiFePO4 Monolithic Cells

Higher energy density and longer cycle life than ordinary cells, compatible with various electrical and digital devices, and lasting power supply

Smart chip, punch and release at the same port

Multiple safety protections, which can be loaded with high-power machines to fully protect the battery, prevent battery damage and prolong battery life

LiFePO4 battery performance:

Light in weight and volume

For a battery pack of the same volume, the volume mass of a LiFePO4 battery is only about 1/3 of that of a lead-acid battery.

Super long life

The cycle life of long-life lead-acid batteries is about 300 times; while the cycle life of lithium iron phosphate batteries is more than 2,000 times

Safe to use

The LiFePO4 battery completely solves the hidden safety problems of the traditional file battery, and it will not explode or catch fire in the most extreme test environment.

Smooth discharge characteristics

Under the same temperature and brightness, the discharge current of different rates is used, and the discharge output characteristics are very stable. Effective protection of locomotive ECU system

Good low temperature start

Lithium iron phosphate batteries can be started normally at -20°C, while traditional batteries can only be started normally at -10°C

Green ring to stay energy-saving and fuel-saving

Lithium iron phosphate batteries do not contain any heavy metals and rare metals, and are non-toxic and non-polluting in production and use, with high discharge platform, low maneuvering emissions, and fuel saving.

Long storage time and small self-discharge

The monthly self-discharge of LiFePO4 battery is less than 1%, and the monthly self-discharge of lead battery is 4-5%

Fast charging with high current

Acceptable 3C charging current
