Dual battery isolator kit keeps your main battery ready to start while safely charging an auxiliary battery for accessories on 12V UTV, ATV, jet ski, and snowmobile setups. This 80A voltage sensitive relay (VSR) supports manual and automatic operation, adds a clear LCD dual-voltage display, and fits tight installs without vehicle modification. Built for mud, spray, dust, cold, and vibration, it helps stabilize power in demanding outdoor conditions.

When winches, lights, radios, and chargers drain power fast, a compact battery isolator with VSR control helps keep your starting battery protected without sacrificing accessory runtime. The small footprint mounts easily in tight bays, and the dual voltage display makes it simple to confirm charging status at a glance before you head out.
