Depth of Discharge

Depth of discharge is the inverse of state of charge (SOC). A battery at 60% SOC is also at 40% DOD. Deep-cycle batteries should be able to maintain a cycle life of several thousand cycles under high DOD (80% or more). For lithium-ion batteries, the cycle life of a cell strongly depends on the DOD. The loss of lithium ions and active electrode ...

Ideal Depth of Discharge for LiFePO4 Batteries

Most LiFePO4 batteries can safely discharge up to 80% or even 90% of their total capacity without causing significant damage to the battery. While you can cycle lithium from 0% to 100%, it is generally not recommended. This can make the battery degrade faster. Always follow the manufacturer''s guidelines for the recommended depth …
