Stop Draining Dead Batteries — Take Full Control of Your Power

A dead battery mid-voyage or a parasitic drain that kills your charge overnight are two of the most frustrating problems on any boat or RV. This 4-position rotary battery selector switch (1 / 2 / BOTH / OFF) lets you instantly isolate, switch, or combine battery banks with a single turn — protecting your electrical system, extending battery life, and giving you a reliable backup when you need it most. Rated at 175A continuous / 300A cranking at 12V DC, it handles everything from engine starts to full house loads. Available in White and Black to match your setup.

Key Features

4-Position Rotary Control — Select Battery 1, Battery 2, BOTH banks simultaneously, or OFF to fully isolate the system
175A Continuous / 300A Cranking — Handles high-demand engine starts and sustained electrical loads
Zinc-Plated Copper Terminals — Superior conductivity and corrosion resistance for long-term marine use
ABS Housing — UV-Resistant & Waterproof — High-gloss ABS material resists deformation, UV degradation, and moisture ingress
Anti-Aging Construction — Built to withstand harsh marine and outdoor environments
Compact & Easy to Mount — Multiple mounting options; fits standard panel cutouts (13.7 × 13.7 cm footprint)
Compatible with 6V / 12V / 24V / 32V Systems — Versatile for boats, RVs, campers, and off-grid setups

How It Works

Position 1 — Powers your system from Battery 1 only; Battery 2 stays in reserve
Position 2 — Powers your system from Battery 2 only; Battery 1 stays in reserve
BOTH — Connects both batteries in parallel when charge is low or maximum power is needed
OFF — Fully disconnects all batteries to prevent parasitic drain when the vessel is stored
