12V Outboard Dual Battery Kit with ACR Isolator — Starting & House Battery

Never get stranded with a dead cranking battery. The RCE12VBM6IK uses an automatic charging relay (ACR) to let your outboard charge both the starting and house batteries, then isolates them so electronics and accessories can't drain the battery you need to start the engine.

Your starting battery is the one you can't afford to lose. Connect-Ease outboard and starting kits use heavy-gauge marine wire and patented plug-and-play connectors so the engine circuit stays secure, accessories stay organized, and the battery comes out in seconds for charging or winterizing.

Frequently asked questions

Common questions about the RCE12VBM6IK.

It combines batteries for charging while the engine runs, then separates them so house loads can't drain your starting battery.

Yes. Confirm your outboard's charging output and use a DC-DC charger if your engine maker recommends it for lithium.
