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. .

Easy to install. The instructions are written in plain English and easy to follow for an average technician with basic electrical knowledge. 137083
Still working as expected! No problems or issues. I installed it with waterproof heatshrink crimp connectors. I have found it pays to spend a little bit more for the added security.

I 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
I 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

Mike L - 12/21/2018Nice 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
So far so good, i trust it to be a solid unit should i ever have a breakaway.
Sal F - 05/26/2016Which the unit would have included spli ces 653785
The breakaway kit is exceptionally well made and priced far below most other suppliers of trailer parts. 650288
All parts ordered were great and work perfect. Thanks. 647084
Appears to be of good quality. All works as it should so far. 637383
Bought one of these. Hooking it up, I thought I had fried the circuitry. Ordered a replacement. Took the old damaged assembly apart to use as parts. Discovered that a terminal had came off the battery. Unit was OK. Now have a spare! 637224
Good replacement, does the job. Good pr ice. 633187
great replacement 619474
Great product 613660
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
Its brand new and it works as it should for now. The life of the battery will tell in some time. 520349
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
This Breakaway kit is just right and includes all the main components needed. Also like the built in battery charging feature as well. 443201

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
Glad I choose this model, works great 418772
all is well and working fine. Your store is the best! could use LESS e-mails Thanks
JR - 09/19/2018Converting from hydraulic surge to electric, this was needed. Install was easy. 406770
The conversion from hydraulic to electric is something I should have done when I first bought the trailer. The parts are working great! I want to say things are working better now than when the trailer was new. It pulls easier, sways less, and stops with confidence.
Dave S - 07/17/2018I HAVE PURCHASED SEVERAL ITEMS FROM E TRAILER . FROM TRAILER PARTS TO REBUILD A CONSTRUCTION TRAILER TO PARTS FROM MY FIFTH WHEEL CAMPER . THE QUALITY OF THEIR PARTS HAS ALWAYS BEEN THE BEST . 407122
Excellent service. Quick and no problems with parts. Just like the other times I have ordered parts 394703
Great product! One year young and battery is still at 100%. 388555
Its been almost 2 years now. The battery is still going strong. Everything works great.
Matt - 06/04/2018Quick delivery 383260
The parts were exceptionally well and for a reasonable price very happy with what I purchased 382791
Great service, great pricing and product ships same day (most cases) and complete every time! 381485
Products received were high quality as advertised and the customer service was awesome. US postal service as the delivery method was less then impressive. Found my package laying on the ground by my mailbox roadside. This by no means was Etrailers Fault but something to consider when they chose a delivery method for their customers. The experience with Etrailers other then this was awsome. Will be ordering more for sure. 380537
Works well. The wire schematics included are a little confusing, but a little thought and common sense can sort it all out. 369783
I not only order from this company for my personal use but also order these products for customers vehicles and trailers? at work. Their prices are excellent and if your unsure of the parts you need the customer service will help you narrow it down to the right part with little waiting. 367461
Product was exactly as described, easy to install, with great instructions. Everything I needed to complete installation on my livestock trailer. Battery charges while hooked to tow vehicle, and is still working great! 363958
Good product, good price , good service. 362939
Great selection. Easy to manage site. Very timely delivery. All products received as ordered. 362733
No problem at all. Wil continue to use your company for trailer needs 360147
As always my shipment was delivered on time. Package contents were all in good shape. The instructional tapes are great. The best thing is the price. 341350
The breakaway battery and charge works great! It keeps the battery charged all the time. I don't have to charge the battery with another charger its automatic as long as you use the trailer once in a while or at least hook it up to a vehicle for a while. 334495
Can't really say much except no issues! Good instructions. Good price from etrailer. Complete kit... Hopefully I will never have to find out "how well" this works. I like the charge indicator light. I'd say very good product for a very fair price for a lot of insurance (and required in CA). A year with no issues. Battery charges. Light indicates. Decent enough instructions to wire it up. "Easy and done" 333727
Works great and was easy to install! No issues at all and have been using it regularly for over a year now. 328384

great everything! 312424
Nice unit 311267
Excellent fast delivery 311001
The product worked great. The wiring instructions that come with it were a bit confusing. 308606
This was a great replacement for the old battery box that came on the trailer. I like that it charges the battery. There is a light on the top that doesn't serve a purpose really, It tells you that the battery is charging. There is a button to push to view it the battery is charged or charging, I am always worried that the light staying on will drain my battery on my truck. Other then the light staying on I would have given it 5 stars. 305510
perfect and fast shipping 300141
I have been working on a horse trailer rebuild. I recently purchased brake drum assemblies, For this order I needed support to help determine the proper parts for the brakes. John provided a fast, knowledgeable response that helped insure that I was ordering the correct part numbers for my trailer. As usual, the order was processed quickly and was delivered fast. All the parts were delivered complete and no damage. Product quality is exceptional. 291583
Product arrived promptly. Easy install as it was a direct replacement. Would have given 5 stars except the battery was dead (recharge light when test button pushed). Would have been a real problem if I did not have a 1.2 amp charger because a larger charger will fry it. 286342
