Should you charge LFP battery to 100 daily?

Short Answer: Lithium Iron Phosphate (LFP) batteries can be charged to 100% regularly without significant degradation due to their stable chemistry and lack of voltage stress. Unlike other lithium-ion batteries, LFPs maintain capacity better under full charge cycles. However, occasional partial charging (80-90%) extends lifespan marginally. Daily charging habits should align with usage needs and manufacturer guidelines.

How Do LFP Batteries Differ From Other Lithium-Ion Chemistries?
LFP batteries use lithium iron phosphate cathodes instead of nickel-manganese-cobalt (NMC) or nickel-cobalt-aluminum (NCA). This grants them superior thermal stability, higher cycle life (2,000-5,000 cycles vs. 500-1,500 for NMC), and lower risk of thermal runaway. Their flatter voltage curve reduces stress during full charging, making 100% SOC (State of Charge) less harmful compared to conventional lithium-ion cells.
What Are the Long-Term Effects of Full Charging on LFP Cells?
Testing by CATL and BYD shows LFP cells lose only 10-15% capacity after 3,000 cycles at 100% SOC. Voltage degradation is minimal due to their 3.2V nominal cell voltage, which avoids the 4.2V stress points of NMC batteries. Calendar aging dominates over cycle aging in LFPs, meaning time impacts lifespan more than charge depth in moderate climates.
