Digital Duo Charge - Battery Combiner

Preset programs for gel, AGM, deep cycle flooded, and standard batteries ensure proper charging even when batteries are of mixed types.
Simply wire the Duo-Charge in series between the main battery bank, the House bank for example, and the secondary battery bank, such as a Starting battery. As the alternator charges the main bank, the secondary bank will get charged, also.
