ATEM POWER Trailer Brake Controller Kit with Solar Panel | LiFePO4 Battery, IP65

Power reliability on every tow

When you’re towing a trailer or caravan, power reliability matters. The ATEM POWER Trailer Brake Controller Kit with Solar Panel combines a compact breakaway controller with a built-in LiFePO4 battery and a compact solar option designed to keep essential indicators alive when you’re off-grid. Designed for 1 or 2 axle caravans and trailers with electric brakes, this kit aims to reduce the risk of power drain and to simplify on-site setup.

Why choose this kit

The built-in LiFePO4 battery brings lighter weight, longer life, and a lower self-discharge rate than common AGM options, with a BMS that guards against overcharge and over-discharge. LED indicators on the unit provide a quick visual read of charge status, so you know when it’s time to recharge or replace. The solar panel is designed to prevent the brake-away controller from running out of power, particularly on longer trips or in areas with limited access to DC power. Note that it does not charge the trailer's brake battery; it's meant to keep the controller alive.

Automatic safety feature

Most breakaway scenarios are unexpected. When there’s a disconnection between your 4x4 and trailer, the kit automatically activates the electric trailer brakes to bring the trailer to a controlled stop. This quick action is designed to enhance confidence on tricky roads or uneven terrain, without requiring manual intervention.

Easy installation and rugged build

The kit is designed for straightforward installation using screws or rivets. It ships with pre-wired, color-coded cables for battery (black), brakes (blue) and ground (white), making wiring predictable. The ABS enclosure carries an IP-65 rating, guarding against rain and dust. With a 3-year warranty and ADR compliance for trailers over 2,000 kg gross mass, it's built to handle real-world use.

What’s in the kit

• Trailer breakaway controller with switch
• Built-in LiFePO4 battery
• Mini solar panel for power resilience
• LED indicators for charge status
• Pre-wired, color-coded cables
• Rugged ABS enclosure, IP-65 rated
• Installation screws or rivets (optional)

Use cases and benefits

• Remote campsites or off-grid trips where access to power is limited
• Road trips with long driving days, where occasional battery drain could occur
• Emergency use in poor weather, where edge power might be needed to keep braking systems ready

Keep in mind: The solar panel’s role is to prevent power loss to the controller, not to recharge the trailer’s own brake battery. For best results, follow the included installation guidance and avoid installation in continuous heavy rainfall. This kit is designed for reliability and ease of use in everyday towing scenarios.
