The instructions for this electronic trailer-brake controller, however, could be better. Fortunately, this device is pretty easy to set up, so it’s not much of a loss, but newbies may want to do a little searching online if they get stuck.

  • Display Type: None

If you want to truly be prepared for everything, you’ve got to check out the Redarc Tow-Pro Elite V3 Electric Brake Controller. This trailer-brake controller offers an impressive amount of versatility, and it puts control in your hands with some great customization options. You can start by choosing between proportional or user-controlled trailer braking force. And if you want the most versatility and customization, user-controlled braking allows you to adjust and change settings based on the roads you encounter, the terrain conditions, your vehicle type, or simply your personal preferences. In addition, the controller offers Active Calibration to constantly monitor your direction, and it can calibrate from any mounting orientation or even if you don’t have your trailer attached.

For some, however, the size and shape of the device itself can be a bit bulky or not perfectly match your OEM accessories. And installation, while not complicated, can take time and require removing some of the trim pieces in your vehicle interior.

You’ll enjoy reverse battery protection and plenty of diagnostic features displayed right on the easy-to-read LED screen. Plus, the included boost mode offers more force for initial trailer braking to give you a safer stopping distance and power. With advanced proportional braking, this controller will help apply brake pressure to match your deceleration rate, a detail that’s especially key when you’re hauling a heavier load. With regular use, it may help extend the lifespan of your vehicle’s brakes.

When it comes to potential disadvantages of this brake controller, keep in mind that it sometimes comes with an incorrect harness. And while the product description mentions a universal connector that’s included, it actually has to be purchased separately.

Backed by a lifetime warranty, this trailer brake controller offers solid reliability. But the design can be a potential drawback. With three individual, separate items to install, it can be a challenge to actually get installed, and the instructions are quite vague and limited.

This device allows for reliable safety and long-term reliability, as it increases the braking pressure for your trailer each time you actually step on the brakes. And it stops smoothly. You can monitor everything via the easy-to-read LED display, which includes no moving internal parts to keep functionality simple. You can enable powerful brake operation with the manual brake slider button, adjustable toggle, and adjustable ramp time. It’ll work with any trailer that has one to three axles and is compatible with cruise control, anti-lock brakes, low-voltage systems, and PWM systems. Plus, it easily and quickly plugs right into place.

This trailer brake controller isn’t without its flaws, however. It’s very sensitive, which makes even the slightest touch to the buttons significant. And it doesn’t include the right bolts you need for installation.

Our Verdict

This device can control up to four axles and includes a handy boost feature, plus simple plug-and-play setup.

What to Consider When Buying a Trailer Brake Controller

Picking out the perfect trailer-brake controller for your towing needs can be a bit complicated. You need to think about the features of your trailer as well as what kinds of features are must-haves in your brake controller. But we’re here to help, and we’ve got all of the advice you need to find just the right device.

Types of Trailer Brake Controllers


A proportional trailer-brake controller uses internal, inertia-based sensors to determine when and how your vehicle brakes. When your tow vehicle decelerates, the sensor reacts and commands the controller to send power to the brakes. The best proportional trailer brake controller provides uniform, smooth braking without any push-pull movements.

Time Delay

With a time-delay trailer-brake controller, you’ll have a bit of a delay when you first apply the brakes. A signal is sent to the brake controller, which sends voltage to the trailer brakes. The delay can be adjusted; you can change it in the sync setting, along with additional settings like the braking power and rate of application. A time-delayed controller can be mounted at any angle because it doesn't have internal parts that sense the tow vehicle's braking motions. These controllers are simpler to install and cheaper but not recommended for larger trailers. 

Trailer Brake Controller Key Features


Voltage is one of the top factors when it comes to finding the best-rated brake controller. A tow brake controller consists of either 12 or 24 volts. The vehicle's power source must be compatible with the trailer's brakes. If the two units don't match, the braking controller may malfunction, increasing the risk of an accident.

Brake System

Trailers with electric brakes are governed by a brake controller, while hydraulic brakes require a special coupler. A towing vehicle does not control this braking element. Certain trailers have both electric and hydraulic components. The best aftermarket trailer brake controller should have the ability to operate both types.


Most trailer-brake controllers are priced below $250. Many of the top products even fall below $100 total. If you’re shopping on a budget, you can find simple and straightforward trailer-brake controllers for $25 to $50, though these products picks tend to have limited extras and are pretty streamlined in their features. Spend $55 to $125, and you’ll be able to shop a wide selection of controllers that include extras like informative LED displays and perks like boost features. And the most premium options may run you $125 and up, including high-tech picks for trailers with over four axles. 


You’ve got questions. The Drive has answers.

Q: What’s better: a timed or proportional brake controller?

A: In most cases, a proportional trailer brake controller is the better pick, especially if you tow regularly or tow heavy trailers. Proportional braking is superior during emergency braking scenarios. A timed brake controller is fine if you only occasionally tow smaller trailers.

Q: Can I tow a trailer with electric brakes without a brake controller?

A: No, you’ll absolutely need a trailer brake controller. Trailers with electric brakes must have one of these devices, otherwise the trailer’s brakes won’t work.

Q: Are all trailer-brake controllers the same?

A: There are two types of trailer brake controllers: proportional or time delay. While both activate a trailer’s brakes and apply pressure to slow you down, one comes with a delay and one is typically better for larger trailers.
