True® UTV-SBI-CMFB Dual Battery Isolator Connect, Monitor, Fuseblock Kit for UTVs

Never get stranded on the trail with a dead battery.

The True® UTV-CMFB (Connect, Monitor, Fuse Block) Dual Battery Isolator Kit from True® is the ultimate off-road power management solution designed specifically for UTVs, Side-by-Sides, and off-road vehicles. When you run heavy power draw accessories—such as light bars, winches, sound bars, heaters, or communication charger—your stock electrical system can quickly get overwhelmed. The UTV-CMFB Dual Battery Management System Kit solves this by allowing you to add a secondary auxiliary battery that charges automatically off your vehicle's existing stator/alternator while keeping your primary starting battery fully isolated and protected.
