GOGONFLY Battery Disconnect Switch 12V–48V Waterproof Rotary Master Isolator

GOGONFLY Battery Disconnect Switch is a rugged, waterproof master power cut-off that isolates 12V–48V systems for safe storage, maintenance, and theft-prevention.

Built for vehicles, boats, and off-grid equipment, this heavy-duty rotary battery switch combines a sealed ABS housing with copper-tinned studs to protect electrical connections from moisture, dirt, and corrosion. The unit accepts a wide range of voltages and delivers high continuous, intermittent, and cranking current ratings, making it suitable for many battery-powered applications. A clear clockwise-on / counterclockwise-off rotation and included mounting and terminal hardware make installation straightforward.

How does this switch protect a stored vehicle or boat?

Turning the GOGONFLY switch to the off position physically disconnects the battery, eliminating parasitic drains from alarms, radios, and control modules. That helps keep batteries charged longer and reduces the chance of a no-start situation after storage. The sealed enclosure also prevents corrosion that could compromise the disconnect over time.

• Fully isolates the battery to prevent parasitic power draw
• Waterproof ABS housing reduces moisture-related failures
• Copper-tinned studs resist corrosion at connection points

What electrical ratings and voltages does it support?

This rotary cut-off is rated for 12V through 48V systems and carries substantial current capacity for demanding starts and loads. Continuous, intermittent, and cranking ratings give a clear picture of performance under different conditions, so you can match the switch to automotive, marine, or light industrial applications.

• Works with 12V, 24V, 36V and 48V battery systems
• 275A DC continuous (1 hour) capacity for sustained loads
• 455A DC intermittent (5 minutes) and 1250A DC cranking (10 seconds)

How easy is it to install and operate?

Installation is designed to be user-friendly: the package includes the switch, mounting bolts, copper ring terminals, heat-shrink tubing, and a hex wrench. Wiring routes through the enclosed body to keep connections clean and secure. Operation is a simple two-position rotation—clockwise to engage power and counterclockwise to cut it off—minimizing accidental changes.

• Comes with 4 mounting bolts and 4 copper ring terminals
• Heat-shrink tubing included for insulated, tidy terminations
• Two-position rotary knob for clear on/off control

Where is this switch typically used and what does it replace?

The GOGONFLY disconnect acts as a compact master isolator for a wide variety of vehicles and equipment, replacing makeshift disconnects, inline fuses, or hard-to-access battery terminals. It is built to handle the demands of RVs, trailers, marine craft, and off-road vehicles while remaining durable in exposed environments.

• Commonly installed in RVs, boats, trucks, ATVs, UTVs, and campers
• Replaces temporary or unreliable battery isolation methods
• Suitable for maintenance shut-off and theft-deterrent use

Who is this for: Owners and technicians who need a reliable, weather-resistant battery master switch that supports 12V–48V systems—especially RV and marine owners, off-road enthusiasts, fleet maintenance crews, and anyone wanting a simple, durable way to isolate battery power during storage or service. The included hardware and clear ratings make this an accessible upgrade for DIY installers and professionals alike.
