ATEM POWER Trailer Breakaway Kit with Brake Controller — 12V 3Ah LiFePO4, Built-in Solar & IP65 Weatherproof

ATEM POWER Trailer Brake Controller Kit is a self-contained breakaway system with a 12V 3Ah LiFePO4 battery, built-in solar panel, LED status lights and a water-resistant IP65 housing to keep your trailer brakes ready while parked or on the road.

This compact breakaway kit combines a modern LiFePO4 battery, an integrated solar trickle charger, and a pre-wired controller into a single weather-resistant unit designed for 1- and 2-axle trailers and caravans with electric brakes. It’s made to preserve battery charge during storage, activate trailer brakes instantly if the trailer separates, and give clear visual status via LED indicators and a push-check button.

How does the built-in solar panel help when my trailer sits unused?

The solar panel constantly tops up the LiFePO4 battery so the breakaway system keeps enough power to actuate the brakes even after weeks of storage. It’s not intended to fully recharge a dead controller battery, but to maintain charge and prevent drain during typical storage conditions.

• Integrated solar cell maintains standby charge over long parking periods.
• Reduces need for manual battery charging between uses.
• Helps ensure the breakaway system remains ready for emergency activation.

Will the LiFePO4 battery deliver reliable power and long life?

The included 12V 3Ah LiFePO4 battery offers lower self-discharge, higher cycle life and lighter weight compared with sealed lead-acid alternatives. It includes internal BMS protection against overcharge and over-discharge, plus LED indicators and a quick-check button so you can confirm battery status before you tow.

• LiFePO4 chemistry for longer useful life and stable voltage output.
• BMS protection for safer charging and discharging behavior.
• LED and push-button status check for fast pre-trip verification.

How quickly will the system activate brakes if the trailer disconnects?

The breakaway controller is engineered to energize the trailer’s electric brakes immediately upon detecting a loss of tow connection, helping slow the trailer until it comes to a stop. The coiled lanyard switch is simple to mount and designed for fast, dependable engagement during an emergency separation.

• Rapid activation circuitry to apply trailer brakes immediately on disconnect.
• Coiled lanyard switch for secure driver connection and reliable trigger.
• Pre-wired, color-coded leads simplify wiring to the trailer brake and ground.

Is this unit rugged enough for outdoor towing and storage?

The battery box and controller are housed in heavy-duty ABS with an IP65 rating to defend against rain spray, dust and road grime in everyday towing conditions. While IP65 affords strong protection, the product is advised to avoid direct exposure during severe rainstorms for maximum longevity.

• IP65-rated enclosure guards internal components from dust and water spray.
• Durable ABS housing resists impact, mud and road debris.
• Compact, mountable design with tidy cable routing and secure fittings.

Who is this for? This ATEM POWER breakaway kit is aimed at caravan and trailer owners who want a low-maintenance, modern alternative to lead-acid breakaway batteries. It’s a good fit for campers, weekend tow-users, small-business trailer fleets and anyone who stores their trailer for extended periods and wants a reliable emergency brake activation system that’s easy to install and monitor.
