LFP battery is the short name for #LiFePO4, also as known Lithium Ferro(Iron) Phosphate Battery. An LFP battery refers to a li-ion battery using lithium iron phosphate as a positive electrode material.

Knowing the relevant voltage of the LFP battery helps to set the reasonable end voltages, so the LFP battery could be working in the most effective and reasonable condition, and offer a safe, stable, and long-lasting power supply.

As the safest lithium technology, the LFP battery has many advantages in energy storage applications.

■LFP Battery Cell Voltage

Due to the difference in various raw materials used by each manufacturer(including positive, negative electrode materials, and electrolytes), the performance and voltage of the batteries are not exactly the same. In general conditions, the nominal voltage of the LFP battery cell is 3.2V, the high-end voltage is 3.6V, and the low-end voltage is 2.0V.

The charging voltage of the LFP battery cell is recommended as 3.65V, 14.6V+-0.2V for a 12.8V battery. 3.65V per cell is proven to be a reasonable charging voltage after long-time practical use.

The relevant voltage of the LFP battery is different in different conditions. Mainly in 3 cases, open-circuit voltage (#OCV), charging condition, and discharging condition. In applications, the charging and discharging voltage are more useful, involving a reasonable set of end voltages to ensure that the battery works in a good and stable situation.
