 DoD is the inverse of //State of Charge (SoC)//.  Example:  a battery at 30% DoD is at 70% SoC.
-DoD has a **significant impact on longevity of lead deep cycle batteries**.((and, to a lesser degree, lithium batteries))  For this reason [[electrical:inverter|Inverters]] and other high-load devices may have a [[electrical:12v:lvd|low voltage cutoff]] to prevent going below a given SoC, typically 50%.
 Note: This information is primarily relevant to lead-chemistry batteries.  Lithium batteries have [[#lithium_soc|different DoD capabilities and lifecycles]].

 So while we can say with confidence that a 100Ah Li battery charged at 20A to 14.0v will be ~100% SoC, the same battery charged to 14.0v at 80A might only be at 75% SoC.  And it **could get damagingly overcharged** if charged to 14.0v very gently at something like 5A.((the BMS cannot detect this scenario))
-The amp counter will probably help here during charging although even it can be thrown off.
+The amp counter will probably help here during charging although even it can be thrown off;  see the battery monitor article for more on this.
