12V Parallel Battery Connection Kit — Dual Battery Power for Boats & Marine Applications

Need more run time from a 12V trolling motor or house system? The RCE12VBPK wires two 12V batteries in parallel — positive to positive, negative to negative — so you keep 12 volts while doubling amp-hours. Connect-Ease plug-and-play connectors make it impossible to cross-wire and let you remove either battery without tools.

Connect-Ease's patented, self-cleaning, positive-lock connectors replace wing nuts and stacked ring terminals at the battery. Install once and every connection after that is plug-and-play — no tools, no crossed wires, no corroded posts, and batteries come out in seconds for charging or winter storage.

Compatible trolling motors and vehicles: Minn Kota Endura, Traxxis, PowerDrive, Terrova and Riptide (12V models); MotorGuide X3, R3 and Xi3 (12V); Newport Vessels and Watersnake 12V motors. Compatible electronics and accessories: Also feeds 12V house loads: Fish finders, GPS, VHF radios, bilge pumps, livewell pumps, LED lighting, USB chargers and shallow-water anchors.

System voltage: 12V (two 12V batteries in parallel). Recommended batteries: Two matched 12V batteries of the same chemistry, age and Ah rating — 12V deep-cycle AGM, flooded lead-acid or 12.8V LiFePO4 lithium (Group 24/27/31, 50–120Ah). Amperage and protection: Plan for up to 50A continuous draw on 12V motors (30–55 lb thrust). Protect with a 50A breaker per motor maker.
