Yes, generally speaking, a solar charger can work with Dakota Lithium batteries. However depending on the wattage and amperage rating of one’s solar panel, a solar charge controller may be necessary. Dakota Lithium offers a 12 volt solar panel that can be directly connected to our batteries without the need for a controller. Please note that any system using more than 20W of solar power it is highly recommended that you use a solar charge controller like our DL Dashboard.
