Lithium Ferro (iron) Phosphate, also known as LiFePO4 or LFP, is a type of lithium-ion battery. Unlike the lithium cobalt batteries commonly found in cell phones and laptops, LFP batteries are more stable and less prone to catching fire. However, if an LFP battery is damaged, it can still be dangerous due to the energy stored in it.
Unlike lead acid batteries, the voltage of a lithium-ion battery remains very constant during discharge, making it difficult to guess the state of charge from the voltage alone.
LiFePO4 batteries will be happier in the long run when they don't stay at 100% SOC for too long, so this practice will extend your battery life. If you absolutely must have 100% SOC in your battery, absorb it will do!
