====== Battery monitors ====== | ====== Battery monitors ====== |

| Battery monitors typically show: |
| |
| * battery voltage ([[meta:acronyms|Vbatt]]); and |
| * Amps or Watts in (charging) / out (discharging) |
| |
| Watching amps trail off at the end of Absorption (endAmps) will also tell you when the bank is [[electrical:12v:charging|fully charged]]. The battery manufacturer will specify something like [[electrical:12v:battery_capacity|C/200]] or C/100 as a sign Absorption is complete. |
| |
| |
| One benefit of having a shunt-based monitor over a [[electrical:solar:status#then_observe_the_controller|charge controller monitor]] is the shunt can discern between [dis]charging vs [dis]charging+loads. |
