An industry changing design that provides intelligent and zero voltage loss isolation, charging of up to 3 other battery banks off a single alternator (model specific). For dual engine applications, ProIsoCharge offers an exclusive 2 alternator input model with up to 4 battery banks. Smart enough to provide priority charging to a battery bank that's under load by taking fully charged batteries off line. The all-in-one design eliminates the need for multiple voltage sensitive relays to charge multiple battery banks simultaneously, saving space, installation time and cost. Ensuring fully charged batteries and faster charge times, ProIsocharge eliminates the typical alternator voltage loss of 0.6VDC that's commonly associated with traditional diode based isolators.
