12v 4 Battery Parallel Kit

Build a big 12V battery bank the right way. This kit includes 16-inch 4-gauge positive and ground cables to parallel four 12V batteries, a 150-amp fuse kit for high-current protection and terminal post covers for safety — ideal for RVs, overland rigs, boats and solar storage.

Off-grid power is only as reliable as its wiring. Connect-Ease camp and RV systems build battery banks with pre-made, plug-and-play connections — no cutting, crimping or guessing at polarity — so you spend less time on wiring and more time off the grid.

Compatible electronics and accessories: 12V house loads, inverters, RV systems and solar charge controllers.

System voltage: 12V (four in parallel). Recommended batteries: Four matched 12V LiFePO4 or AGM batteries. Amperage and protection: 150A fuse included for main bank protection.
