Description
Your cranking battery, your trolling battery, and your accessories battery are three different jobs. Running them without a proper switch means you're one bad draw away from a dead motor, a dead trolling system, or both — on the water, mid-tournament, with no backup plan.
The Monster Marine Lithium 3-Way Battery Switch puts you in complete control. Switch between battery banks, combine them for maximum output, or isolate individual systems with a single turn. Marine-grade construction handles the punishment of harsh water environments — corrosion-resistant, heavy-duty, and built to the same standard as every other piece of Monster Marine gear.
3-Way Switching — All Your Options, One Switch Position 1: Battery Bank A only. Position 2: Battery Bank B only. Position ALL: Both banks combined for maximum power output. Isolate systems, protect your starting battery, or combine banks when you need everything firing at once.
Heavy-Duty Marine-Grade Build Corrosion-resistant housing engineered for saltwater, freshwater, and everything in between. Handles the vibration, moisture, and heat of real on-water use without failure.
Smarter Power Management Keep your cranking battery reserved for starting. Run your trolling motor and electronics off a dedicated bank. Combine when conditions demand it. Stop waking up to a dead boat.
Simple Installation Compact, intuitive design mounts cleanly in any console or electrical panel. No complicated wiring — straightforward hookup gets you running fast.
Perfect For:
- Separating cranking and trolling motor battery banks
- Managing dedicated electronics or accessory circuits
- Multi-battery lithium setups running graphs, sonar, live wells & pumps
- Any boat running 2+ battery banks that needs organized power control
