Mastervolt Battery Mate 2503 IG Isolator - 200 Amp, 3 Bank

The Mastervolt Battery Mate 2503 IG is a 200 amp battery isolator for systems that need to charge three battery banks from an alternator and/or battery charger. It is intended for new installations or upgrades where multiple batteries need controlled charging without alternator adjustment.

Electronic mosfet technology helps limit voltage loss between the charging source and the batteries, supporting proper charge voltage across several banks. The IG contact can be used in applications where the standard alternator requires external excitation or voltage sensing.
