• Configuration Options: 1 alternator to 3 battery banks (model-specific); 2-alternator input model supports up to 4 banks for dual-engine setups

The ProIsoCharge180 delivers smarter charging by distributing the full output of a single alternator to multiple banks while keeping the engine start battery healthy. Its Ignition Controlled Distributed On Demand mechanism activates battery management only when the ignition is on, reducing parasitic draw and extending battery life. With real-time status, objective priority charging, and clear LED indicators, you gain visibility and control over charging across banks, enabling faster starts and longer-lasting batteries in challenging marine conditions.
