Fully discharging a LiFePO4 battery can cause irreversible damage to its cells. This is because the voltage drops too low, which can lead to chemical reactions that degrade the battery''s internal components. Over time, repeated deep discharge cycles can reduce the capacity and efficiency of the battery.

Depending on battery chemistry, DoD can vary widely — from 50% (lead acid) to 80% (Li-ion/LiFePO4). DoD significantly impacts how much electricity you can use without permanently damaging a battery.
