We researched and compared the top trailer breakaway kits based on manufacturer specifications, published safety standards (FMVSS 571), and aggregated owner feedback. A breakaway kit is required by law for most trailers over 3,000 lbs and ensures the trailer brakes activate if it detaches from the tow vehicle. Our evaluation focuses on battery type, switch quality, wiring gauge, and overall reliability. We did not perform hands-on lab testing but analyzed hundreds of user experiences to bring you this guide.

1. Hopkins 20060 Breakaway Kit: Best Overall
The Hopkins 20060 is a complete breakaway kit that includes a battery, charger, switch, and wiring harness. In our research, owner feedback consistently praised its straightforward installation and reliable performance. The sealed lead-acid battery holds charge well over winter storage, and the switch is strong. We found that this kit meets DOT and FMVSS standards, making it a safe choice for most trailers.
However, some users noted that the battery charger can be slow and the battery may need replacement after a few seasons. This kit is ideal for boat and utility trailers up to 7,000 lbs. Skip it if you need a lithium battery for weight savings or a higher amp-hour capacity for larger trailers.
- Complete kit with everything needed for installation
- Sealed lead-acid battery with automatic charger
- Compliant with DOT and FMVSS standards
Pros: Easy to install with clear instructions; Reliable switch mechanism evaluated by many users
Cons: Battery may require periodic maintenance
2. CURT 52040 Breakaway Kit: Best Value
The CURT 52040 is a budget-friendly breakaway kit that still delivers solid performance. We compared it to other kits in its class and found it includes a battery, charger, switch, and a handy mounting bracket. Owner feedback indicates it works well with electric and hydraulic brakes, and the compact size fits easily on smaller trailers.
On the downside, the included charger is not a smart charger and can overcharge if left connected. Some users reported the battery lasted only a couple of seasons. This kit is best for those on a tight budget or for light-duty trailers. Skip it if you want a maintenance-free battery or a faster charger.
- Affordable complete kit with mounting bracket
- Works with electric and hydraulic brakes
- Compact design fits tight spaces
Pros: Good value for the price; Bracket included for easy mounting
Cons: Charger is basic and slow
3. Dexter DX10K Breakaway Kit: Premium Pick
The Dexter DX10K is a premium breakaway kit designed for larger trailers and heavier loads. We evaluated its specifications and found a 7Ah battery, which provides more reserve power than standard 5Ah kits. The switch uses stainless steel contacts for corrosion resistance, and the smart charger prevents overcharging. Owner feedback from RV and heavy equipment trailers is positive.
The main drawback is the cost, which is significantly higher than competitors. Also, the larger battery may not fit in all battery boxes. This kit is ideal for trailers over 7,000 lbs or for those who want extra confidence on the road. Skip it if you are on a budget or have a small trailer.
- Higher capacity 7Ah battery for larger trailers
- Heavy-duty switch with stainless steel contacts
- Includes a smart charger with auto shut-off
Pros: Longer battery life between charges; Rugged construction suitable for harsh environments
Cons: Higher price point
4. Red Hound Auto Breakaway Kit: Budget Friendly
The Red Hound Auto breakaway kit is the most affordable option we researched. It includes the essential components: battery, charger, and switch. Based on owner feedback, it works for light-duty trailers and satisfies legal requirements for breakaway systems. The kit is compact and easy to install.
However, we found several reports of batteries failing within a year or the charger not working properly. The switch is also less solid than pricier options. This kit is a temporary solution or for those who rarely tow. Skip it if you need a reliable system for frequent towing or heavy loads.
- Lowest price among complete kits
- Basic functionality meets legal requirements
- Lightweight and compact
Pros: Very affordable; Works out of the box
Cons: Battery and charger quality are inconsistent

Owner feedback highlights the ease of installation thanks to color-coded wires and clear instructions. Tekonsha is a well-known brand in braking systems.
That said, the battery is standard and may not last as long as higher-capacity options. Some users wished for a smart charger. This kit is perfect for small trailers, utility trailers, or where space is at a premium. Skip it if you need a larger battery for long trips or heavy trailers.
- Very compact size fits small battery boxes
- Easy to install with color-coded wires
- Reputable brand in trailer braking
Pros: Space-saving design; Simple installation
Cons: Battery capacity is standard, not enhanced
6. Optronics BKM-12 Breakaway Kit: Easiest Install
The Optronics BKM-12 is designed for quick installation with a pre-wired harness and battery box. In our research, many users appreciated that they could install it in minutes without any wiring experience. The battery is included and the charger is basic. It is a good choice for DIY beginners.
However, the switch is plastic and some owners reported it breaking after a few years. The battery is also on the lower end of quality. This kit is best for those who prioritize ease of installation over long-term durability. Skip it if you need a rugged system for off-road or marine environments.
- Pre-wired harness for plug-and-play installation
- Includes a battery box with mounting holes
- No cutting or splicing required
Pros: Extremely easy to install; All-in-one box
Cons: Switch is less durable than metal alternatives

The Kohree breakaway kit is a complete package that includes a battery box, wiring, and connectors. We noted that it offers good value for the components provided. Owner feedback mentions that the battery box is sturdy and the kit works well for standard trailers. The wiring is long enough for most installations.
However, the charger lacks automatic shutoff, which can lead to overcharging if left connected. Some users also reported the battery failing prematurely. This kit is a solid choice for those who want a complete set without buying extras. Skip it if you prefer a smart charger or need a higher-capacity battery.
- Comes with a durable battery box
- Includes extra wiring and connectors
- Compatible with most trailer brake systems
Pros: Everything included in one box; Good customer support
Cons: Charger is not a smart charger
Frequently Asked Questions
What is a trailer breakaway kit and why do I need one?
A trailer breakaway kit is a safety device that activates the trailer’s electric brakes if the trailer becomes detached from the tow vehicle. It includes a battery, a switch, and wiring. Federal law requires breakaway kits on most trailers over 3,000 lbs to prevent runaway trailers. Even if not required, it is highly recommended for safety.
How do I install a breakaway kit?
Installation typically involves mounting the battery box and switch to the trailer frame, connecting the switch to the trailer’s breakaway cable, and wiring the battery to the brake controller circuit. Most kits come with instructions. Always disconnect the battery before installation and test the system by pulling the pin.
How often should I test my breakaway kit?
It is recommended to test the breakaway kit before each trip. Pull the pin on the switch; the trailer brakes should engage and hold the trailer. Also check the battery voltage with a multimeter; it should read above 12.4 volts. Replace the battery if it cannot hold a charge.
Can I use a lithium battery in my breakaway kit?
Some breakaway kits are designed for lithium batteries, but most standard kits use sealed lead-acid (SLA) batteries. Lithium batteries are lighter and have longer life, but they require a compatible charger. Check the manufacturer’s specifications before swapping. Some kits may void warranty if not using the included battery type.
What size breakaway kit do I need for my trailer?
The required battery capacity depends on the trailer’s brake system and weight. Standard 5Ah batteries are sufficient for most single-axle trailers up to 7,000 lbs. For tandem axles or heavier trailers, a 7Ah or larger battery may be needed. Always consult your trailer manufacturer’s recommendations.
