Allows your engine's alternator to charge your cranking and accessory batteries.
Connects batteries together in parallel while driving, then separates them once the voltage drops below 12.7v to protect your cranking battery from getting drained by your accessories.
Rated for 300 amps continuous current flow, and spikes of up 2500 amps for 10 seconds to handle anything you can throw at it.
Compatible with all modern high output alternators.
Uses NO power to keep batteries connected, allows batteries to stay fully charged when not in use and run accessories even longer.
Generates NO heat, since no current is flowing through it while the batteries are connected, the battery combiner produces no heat at all.
More robust and more reliable design means more worry-free adventures
