Are you looking to camp off-the-grid? To unshackle from shore power you will need a way to easily generate power. The cleanest, and easiest way to re-charge your Dakota Lithium batteries is via solar power.
Here’s a size chart for what solar panels you need by size of RV/van/camper & how many Dakota Lithium batteries you have.
To connect solar panels to a lithium battery you will need a lithium compatible solar charge controller (a deep dive on RV electrical systems is available here). To connect lithium batteries to charge from an engine’s alternator you will need a DC-DC battery charger. Every Dakota Lithium battery includes a free lithium battery charger for charging via shore power.

Please note, RVs and vans tends to have multiple small solar panels instead of a single big solar panel. This is because the roof top of a van or RV tend to have vents, like a kitchen vent, or an air conditioner, or a fan or skylight that makes it hard to install a single large panel. To better use the rooftop space consider connecting a number of smaller, 100 watt panels together. This will achieve a higher solar panel capacity while offering redundancy — if one of the panels gets damaged the rest will still be able to power your system
