Is it bad to completely drain a LiFePO4 battery?
Fully draining a LiFePO4 (lithium iron phosphate) battery can significantly reduce its lifespan and performance. Unlike traditional lithium-ion batteries, LiFePO4 cells tolerate deeper discharges better, but consistently dropping below 10% state-of-charge accelerates chemical degradation. Most manufacturers recommend maintaining a 20-80% charge range for optimal longevity while allowing occasional full discharges in emergencies. Deespaek 12V 100Ah … Read more
