A simple solution to an ever increasing problem - a DC to DC battery charger that will charge a 12V battery from a 24V battery source with 4-stage operation. In many RVs and motorhomes the engine has a 24VDC system, but the house battery system is 12VDC system, and there is usually no way for the engine alternator to charge the house batteries when driving. This nifty product solves that issue, charging the 12V house batteries from the 24V engine alternator whilst also providing electrical isolation to avoid any nasty surges going either way. Suitable for all types of lead-acid batteries, with selections for different charge voltages, and provides up to 40A of charge current to the 12V battery.
