Projecta 12V 150 Amp Electronic Dual Battery Isolator (DBC150)

Power your adventure with confidence using the Projecta DBC150 Electronic Dual Battery Isolator — the ultimate solution for managing dual battery systems in larger 4WD vehicles and marine setups. Crafted by Projecta, a trusted Australasian leader famed for rugged, professional-grade power management products, this advanced isolator ensures your starting battery stays charged and protected, no matter how demanding your accessories are.

Seamless Smart Battery Management

The DBC150 features intelligent priority charging controlled by a built-in microprocessor, automatically charging your main starting battery first before linking the auxiliary battery. This prevents your essential starting battery from draining when you're running high-draw devices like fridges, lights, or inverters with the engine off.
