RV & CARAVAN LITHIUM BATTERY FAQS

What settings does my shunt require to read my battery correctly?

Please refer to the screenshot above. The only thing that will vary is the battery capacity.

Can I swap my caravan's AGM battery for a lithium one?

Replacing your AGM battery with a lithium battery ultimately depends on your charger because AGM and lithium batteries operate on different charging cycles and chemistries. While lithium batteries are lighter, more efficient and offer a longer lifespan, they require precise charging to ensure safety and prevent overcharging.

Meaning you cannot necessarily make a direct swap of an AGM battery to lithium without first checking your existing equipment. Review your existing chargers and other equipment manuals to confirm lithium battery compatibility. Be sure to check for lithium support in your DC-DC charger, solar charge controller, and 240V charger, among other equipment to ensure a smooth and safe transition.

What orientation can my battery be mounted?

Our RV & Caravan Batteries can be mounted on their base, side or the non-terminal end. As long as the terminals are not facing down.

Are Custom Lithium RV batteries IEC-62619 certified?

All Custom Lithium batteries are made with high quality IEC 62619 certified components and meet the AS/NZS 3001 recommendations.
