FIERYRED Trailer Breakaway Kit with 3.4Ah LiFePO4 Battery, Built-In Charger & LED Test Button

When a trailer becomes disconnected from the tow vehicle, the breakaway kit is the device that applies the trailer brakes so the rig can stop safely. This FIERYRED assembly combines the breakaway switch, an internal long-life LiFePO4 battery with battery management protection, an onboard charger, and a visible LED test and status indicator into a compact, pre-wired housing designed for straightforward installation and reliable performance.

How does this kit activate the trailer brakes in an emergency?

Once the safety cable pulls free during an uncoupling event, the mechanical test-button switch completes the circuit and sends power from the internal battery to the trailer's electric brakes. The result is immediate braking without relying on the tow vehicle's power source.

• Pre-wired switch connects directly to electric brake circuit
• Internal 3.4Ah LiFePO4 battery supplies immediate power for braking
• Robust mechanical action ensures activation under load
• DOT-compliant design meets legal towing safety requirements

What makes the LiFePO4 battery better than traditional batteries?

The included LiFePO4 chemistry is lighter, more cycle-stable, and holds charge longer than many sealed lead-acid alternatives. FIERYRED’s integrated battery management system safeguards against overcharge and deep discharge to extend usable life and reliability.

• Lower self-discharge rate keeps the unit ready longer between uses
• Built-in BMS protects against overcharge and over-discharge
• Lightweight 3.4Ah capacity reduces weight without sacrificing reserve power
• Designed for repeated charge/discharge cycles with consistent output

How do I check battery charge and keep the kit ready before towing?

FIERYRED includes a simple LED test button on the housing that indicates charge status in seconds—press it during pre-trip checks for a visual confirmation. The kit also features an onboard charger so you can maintain full charge while the unit is installed or during storage.

• Push-button LED test gives instant, easy-to-read status
• Onboard charging capability keeps battery topped up between uses
• Mounted-in design reduces wiring mistakes and speeds installation
• Visual indication helps comply with routine safety inspections

How durable is the enclosure and where should I mount it?

The breakaway assembly is housed in a rugged ABS case with an IP65 rating to resist dust and water spray, suitable for many trailer environments. While the unit withstands splashes and light moisture, FIERYRED recommends mounting it in a sheltered location away from prolonged exposure to heavy rain to maximize service life.

• Rugged ABS housing shields internal components from debris
• IP65-rated for dust protection and water spray resistance
• Compact design fits a range of mounting locations on trailers
• Removable control assembly allows convenient access and service

Who is this for? Owners and operators of trailers that use electric brakes—boat trailers, utility trailers, equipment haulers, and similar rigs—will benefit from this FIERYRED breakaway kit. It’s aimed at anyone who needs a DOT-compliant, low-maintenance emergency brake controller with a long-life LiFePO4 battery, easy visual charge checks, and a weather-resistant enclosure for dependable towing safety.
