ATEM POWER Trailer Breakaway Kit with 12V 3Ah LiFePO4 Battery — Built-in Solar Panel, IP65 Waterproof

ATEM POWER's Trailer Breakaway Kit combines a 12V 3Ah LiFePO4 battery, built-in solar panel, and a compact breakaway controller to keep your trailer's emergency brakes ready when you need them.

Whether you tow a caravan, camper, utility trailer or work trailer, a dependable breakaway system is an essential safety item. This kit pairs a light, long-life LiFePO4 battery with a small solar cell and a waterproof housing to maintain charge during storage and to trigger trailer brakes instantly if the hitch separates. The unit is designed for 1- and 2-axle trailers with electric brakes and is built for straightforward installation and low-maintenance use.

How does the built-in solar panel help maintain the breakaway system?

The integrated solar cell tops up the LiFePO4 battery while your trailer sits parked, reducing the chance of a drained battery when you next tow. It’s intended to preserve charge rather than provide active running power for the controller, keeping the emergency circuit ready over long storage periods.

• Small solar panel installed on the case maintains battery voltage during storage
• Extends time between manual charging for seasonal trailers and caravans
• Prevents unexpected battery drain that can disable the breakaway circuit
• Note: solar panel preserves charge; not intended as primary charging source

What are the advantages of the 12V 3Ah LiFePO4 battery in this kit?

LiFePO4 chemistry gives higher cycle life, lower self-discharge and lighter weight compared with traditional lead-acid packs. The battery’s onboard battery management system protects against overcharge and deep discharge, and LED indicators plus a status button make pre-trip checks quick and reliable.

• Longer useful lifespan than lead-acid equivalents
• Lower self-discharge keeps charge months longer in storage
• Built-in BMS for safer charging and discharging behavior
• LED status and a test button for simple visual battery checks

How quickly will the breakaway controller respond in an emergency?

The controller is engineered to activate the trailer’s electric brakes immediately if the breakaway switch is pulled or the trailer separates. Quick activation helps slow the trailer promptly, adding a safety layer that can reduce the chance of a runaway trailer in towing incidents.

• Fast-acting breakaway activation to engage trailer brakes
• Pre-wired, color-coded connections simplify correct wiring to brakes and ground
• Coiled lanyard switch mounts to the tow vehicle for automatic triggering
• Designed for 1- and 2-axle trailers with electric brake systems

Is the unit durable enough for outdoor towing conditions?

The kit is housed in heavy-duty ABS and rated IP65 for protection against dust and jets of water, so it’s suited to dusty roads, gravel tracks and normal outdoor exposures. The manufacturer recommends avoiding severe rainstorms for prolonged direct exposure despite the IP65 rating.

• ABS enclosure resists impact and road debris
• IP65 rating protects internal components from dust and water spray
• Compact, mountable box and coiled switch tidy installation on trailer frames
• Designed for towing environments including camping and work sites

Who is this for: RV owners, caravan and camper trailer enthusiasts, landscapers, builders and anyone who tows a 1- or 2-axle trailer with electric brakes and wants a low-maintenance, long-life breakaway solution. If you store your trailer for weeks at a time, frequently tow on mixed surfaces, or prefer LiFePO4 battery reliability and simple status checks, this ATEM POWER kit provides an easy-to-install safety upgrade without heavy or complex wiring.
