DC to DC Battery Chargers

Installing an auxiliary battery requires a charge controller or isolator to safely and effectively charge the auxiliary battery without damaging the alternator or starting battery. In years past, this would be a simple battery isolator; however, with today's modern vehicles equipped with variable voltage alternators and many auxiliary battery types moving to lithium, a more modern product is required.

But with a modern solution comes added benefits. Products like the REDARC Manager 30 or BCDC not only charge the auxiliary battery via the alternator but also include a built-in controller for solar panel power input. With one product, two power sources can be controlled to power the auxiliary battery while keeping the main starter battery isolated.
