BUNKER INDUST Trailer Breakaway Kit with Charger and LED Display — 12V 5Ah Battery, Side-Mount Safety

The BUNKER INDUST Trailer Breakaway Kit is a complete safety system that automatically applies trailer brakes if the trailer becomes uncoupled, and includes a charger, LED status display, switch, and a 12V 5Ah battery.

Designed for trailers already equipped with electric brakes, this all-in-one breakaway kit provides an immediate electrical brake application in the event of separation from the tow vehicle. The unit combines a compact breakaway module, a sealed 12V 5Ah battery, a visible LED state display and an easy-to-operate breakaway switch. Components are built for outdoor use with weather- and corrosion-resistant materials and a side-mount form factor that simplifies installation and servicing.

How does the breakaway system protect my trailer during an uncoupling?

When the trailer separates from the tow vehicle, the breakaway switch closes the circuit, powering the battery and sending current to the trailer's electric brakes. This immediate activation helps bring the trailer to a stop and reduce uncontrolled movement. The kit is intended to work with existing electric brake systems and requires correct wiring to the trailer's brake controllers.

• Instant electrical brake application on separation
• Compatible with electric brake-equipped trailers
• 12V 5Ah sealed battery supplies sufficient hold-down power
• Durable housing resists weather and corrosion

What does the LED display and charger tell me about readiness?

The integrated LED display gives a quick visual readout of battery condition and charger activity so you can confirm the kit is ready before towing. A push-to-test function illuminates indicators for fully charged, charging, or low battery requiring recharge. The included charger maintains the battery when connected, reducing the chance of a discharged battery when you need it most.

• Push-to-test LEDs for instant status verification
• Indicators for fully charged, charging, and recharge needed
• Charger connection keeps battery topped during storage or use
• Helps avoid unexpected battery failure on the road

How easy is installation and what mounting options are available?

The kit uses a side-mount design intended to make physical installation straightforward and accessible for routine checks. Wiring ties into the trailer's existing electric brake circuit and the breakaway switch mounts near the hitch area so it will activate if the trailer separates. The package includes the breakaway unit, 12V battery and the breakaway switch to complete the system.

• Side-mount housing for convenient access and inspection
• Quick-connect wiring to tie into existing electric brakes
• All necessary components included for a complete installation
• Weather-resistant construction suitable for outdoor mounting

What maintenance does the kit need to stay reliable?

Routine visual checks and testing of the push-to-test LEDs are the simplest ways to confirm functionality before each trip. Keep the charger connected when the trailer is parked long-term to maintain battery health, and periodically inspect wiring connections and the switch for corrosion or wear. Replace the battery if it no longer holds a charge or if the LEDs indicate repeated recharge is needed.

• Push-to-test before towing for a quick functional check
• Use the charger during storage to preserve battery life
• Inspect wiring, switch, and housing for corrosion or damage
• Replace battery when capacity declines or fails tests

Who is this for: The BUNKER INDUST Trailer Breakaway Kit is aimed at trailer owners and DIY installers who already have electric brakes and want a compact, weather-resistant breakaway system with visual status reporting. It's suitable for caravans, utility trailers, small horse trailers and other towable rigs that require a reliable, easy-to-install breakaway activation solution with an included charger and 12V 5Ah battery.
