This is a 3.2V 277AH solar energy storage system Lifepo4 battery. The quality is very good, the actual capacity is higher than the specification, it can be as high as 285AH, it has 3000 cycles of DOD 80%, and the internal resistance is ≤0.40mΩ. Lithium iron phosphate battery is a kind of lithium ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single unit is 3.2V, and the charge cut-off voltage is 3.6V~3.65V. Lithium iron phosphate batteries have a series of unique advantages such as high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, no memory effect, and environmental protection.
