DC-DC Chargers

Power your lithium batteries safely while you’re underway.

A DC-DC charger allows your engine’s alternator to properly charge your house battery bank while protecting both your batteries and alternator. Whether you’re upgrading to lithium or adding a dedicated house bank, a DC-DC charger helps deliver the correct charging profile and reliable performance.

At Onboard Marine Goods, we carry Victron Energy DC-DC chargers, including the popular Orion XS and Orion-Tr Smart series. If you’re unsure which model is right for your boat, we’re happy to help you choose the correct charger, wire size, fuse protection, and installation components.
