Today, we'll be reviewing part number 50-85-315. This is the Pro Series Push to Test Breakaway Kit with the Premium integrated charger. Breakaway kits are designed to bring trailers to a stop by activating the electric brakes, should your trailer come disconnected from the tow vehicle during transit. In a lot of states, breakaway kits are required with trailers over 3,000 pounds. Here on the top, we have a push to test LED, that's going to indicate fully charged, charging, or needs to charge. As we push that button, you can see that we have a nice bright indicator that shows that our battery is fully charged. The built in battery charger is going to charge the battery when plugged into the tow vehicle. It's also going to be able to activate the trailer brakes when separation occurs of the trailer and the tow vehicle. The system is designed for use on 1, 2, or 3 actual trailers with the electric brakes. What you see is what you get, so you're going to get the battery box with the charger, breakaway switch, and a 5 amp battery. There's also an optional, post mount bracket that is sold separately. You can find out in etrailer.com with part number 50-85-115. Here on the back, you can see the mount that we have.
Also, we have 1 mount on the switch. No hardwares included. In order to get this on there, you can bolt the breakaway switch bracket to the frame of the trailer or the battery case bracket, using quarter inch bolt and lock nuts or 2 quarter inch jam nuts. Again, hardware is not included. We'll take a measurement from center to center of these mounting holes, it's going to measure 5 and eleven sixteenths and then, center to center of those 2 holes is going to measure right at 1 inch. Here on the side, we have the wires coming out. The white wires is going to indicate our ground, the black is going to be for the vehicle battery, and the blue is going to be for the brakes and the switch. The battery box is going to measure about 7 inches by 4 and a half and then it's going to stand about 4 and 1 quarter inches in height. Our switch is going to give us a width of an inch and a half and then it's going to give us an overall length from the bracket to the back of the switch, of about 4 and a half inches. That's going to do it for today's review of part number 50-85-315. This is the Pro Series Push to Test Breakaway kit. .

This break away kit is nice and easy to install. The indicator buttons on the top, are a really nice feature. It works good. 573084
Nice product but poor packaging by trailer. Product arrived damaged and since I needed to use my trailer the next day, I repaired it myself. Etrailer should have place the thin product box inside a better shipping box. They may have saved cost on their end but now have an unhappy customer. 195255
Sal F - 05/26/2016I was recommended this drop hitch by an etrailer employee (to use with a trailer that I completely refurbished, with parts almost exclusively from etrailer.com), and have been using it for a year now. It has been absolutely fantastic, and just what I needed. I am always confident that I'm using a quality product to tow my trailer with, which is imperative when my fur babies are along for the ride! My only complaint, is that the hitch does not come with a square cap to prevent water from sitting within the tubing of the hitch - it's cheap and not hard to find, but would be nice to accompany the hitch at the time of purchase. 337873
Easy to install. The instructions are written in plain English and easy to follow for an average technician with basic electrical knowledge. 137083
Eric G - 06/26/2015I have been having trouble with my trailer brakes and noticed that the existing battery was no longer bolted to the trailer, but was loose in the storage compartment. Since it was several years old I decided to replace the whole system. The new one has a charging system , which will keep the battery charged. I will have to do some rewiring,but that will not be a problem. Thanks . This looks like a good system and i can't wait till I get some good weather to work on the trailer. 592301

Wow, can't believe it has already been a year...This item replaced a VERY old system that had served me well...Easily installed...Luckily, have not had to try it out, but with the handy battery condition check button, I know the battery is charged and ready to work if needed. 519833
Really nice and easy to install. Clear instructions. 513577
This unit replaced an existing Pro Series breakaway system. Instructions were clear and the unit matched the existing holes. Operationally the system performed as expected. 510218

Lori L - 10/07/2018Great product easy to install Great customer service 435899
The break away brake was easy to install and works as required. This went on a 16 foot cargo trailer, replacing the original equipment. I was leaving on a trip to California and I wanted to make sure worked properly. 430693
Converting from hydraulic surge to electric, this was needed. Install was easy. 406770
