Alternator charging may bring some battery chemistries (like lithium) to **unsuitably high voltages**. A [[electrical:12v:hvd|high voltage disconnect]] can [[electrical:12v:alternator charging hvd|restrict alternator charging to lower voltages]]. [[electrical:12v:b2b|DC-DC chargers]] can also regulate voltage provided to the house battery. | Alternator charging may bring some battery chemistries (like lithium) to **unsuitably high voltages**.

**Idling the engine** to charge house batteries **can seriously overheat the alternator**. It is usually cooled by wind from the vehicle's forward motion; a fan may help cool the alternator. | **Idling the engine** to charge house batteries **can seriously overheat the alternator**.
