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

| Battery monitors typically show battery voltage ([[meta:acronyms|Vbatt]]), Amps or Watts in (charging) / out (discharging). Amp counting is an important metric because voltage on a circuit is affected by current, particularly if the wire is undersized. |
| |
| Watching amps trail off at the end of Absorption (endAmps) will also tell you when the bank is at 100% State of Charge. The battery manufacturer will specify something like [[electrical:12v:battery_capacity|C/200]] or C/100 as a sign Absorption is complete. |

This monitor will interface and operate their [[https://amzn.to/2SuOYmr|SX-2030 solar charge controller]]. The monitor will still provide amp-counting and other metrics when used on it's own. | This monitor will interface and operate their [[https://amzn.to/2SuOYmr|SX-2030 solar charge controller]].
