Features
Independent bank operation allows two batteries to charge or maintain simultaneously without sharing output or reducing performance. Each bank runs its own full ISM cycle, handling bulk charging, absorption, and float maintenance automatically to help maximize battery life and reduce maintenance effort.
Engineered for harsh onboard conditions, the unit is UL marine ignition protected for safe installation in enclosed or fuel-adjacent compartments. A fully sealed, waterproof design paired with dual-bank architecture makes it a dependable solution for both recreational and commercial marine applications requiring reliable power management.
