In a dual battery setup, a DC-DC charger allows you to charge an auxiliary battery from the alternator whilst driving. With the DC-DC charger, the main battery remains unaffected and is always ready to start the car. And the DC-DC charger can activate lower input voltage operation to suit vehicles with smart alternators. This 12V DC-DC battery charger can utilize a solar panel or a starting battery linked to the alternator while giving priority to a solar input to place less load on the alternator. The DC to DC charger is suitable for LiFePO4 and lead acid: AGM, gel & calcium batteries, and allows you to re-select the battery during charging. With the memory function of this battery to the battery charger, you don’t need to re-select the same battery type every time. And 6-stage charging is engineered for better maintenance & longer lifespan of the battery. If you’re planning off-grid camping, this 20A DC-DC battery charger will be your perfect companion for a dual battery setup.
