Today we'll be reviewing part number 50-85-313. This is the Tekonsha Push to Test Breakaway Kit with a Premium Integrated Charger. Breakaway Kits are designed to bring trailers safely to a stop by activating the electric brakes so the trailer disconnects from its own vehicle during transit. Ideally, the safety chains would make that prevention but in some case this can be used as a last line of defense to bring that trailer to a stop in case it was to ever disconnect. In a lot of states this type of safety system is required for trailers that weigh more than 3,000 lbs so you definitely want to check into that to see if this would be a requirement for your application. The system features a push to test LED indicator here on the top. Once you push that green button, 1 of the 3 LED lights is going to eliminate so it's either going to indicate that you have a fully charged battery, a charging battery or that your battery needs a recharge. This breakaway system is for 1 to 3 axle trailers with electric brakes. The battery box has a battery inside that is included, so it's going to come with the battery box, the battery, all the wiring and the breakaway switch.
The only thing that you should need to purchase is the mounting hardware. It has an integrated multi-stage charger that's going to charge at the ideal charge current to quickly bring voltage up and extend the life of your battery. It has built-in Smart Adjust that changes to an ideal maintenance charge when the battery is fully charged. Once it is fully charged, the automatic float mode is designed to provide a continuous charge without overcharging. This does have a full charge green light that's going to indicate only when the battery is at 12.8 volts or higher. This does require a flat surface mounting. You can see that we have the mounting pattern here on the back.
The distance between our holes from center to center is going to measure 1" and going across is going to measure 5-5/8", center to center. Again, this is designed for up to 3 axles. The way that this mounts is you're going to mount the battery case to fit to the frame of your trailer with the breakaway switch cable towards the tow vehicle. The switch location should be selected to ensure unobstructed line of pull in the event of a vehicle separation. Then you can bolt the breakaway switch bracket to the frame of the trailer or case bracket using a 1/4" bolt and lock nut or you can use 2 individual 1/4" jam nuts. You want to be sure to wire everything per the instructions, those are included as well and they have really nice wiring diagrams that way you can be ensure that you're going to have a correct wiring situation and that everything is going to be wired correctly for your application. Then you can attach the breakaway switch cable to your tow vehicle frame being certain that the cable does not drive on the ground and that no restraint or restriction is placed on the cable itself. To go over the wires real quick, the wires that come from the switch both of them are going to be black wires.
One black wire is going to connect to the trailer brake wire and the other wire is going to connect to the blue wire from our battery box. It does not matter which black wire you use to make those connections; the switch really doesnt care and so you're going to be safe choosing either one of those black wires to connect to either the trailer brakes or the blue wire from the battery box. Here at the battery box we have a white wire which is going to be a ground wire and then we have the black wire that is our charging circuit wire and then we have the blue wire that goes to 1 of the black wires from the switch. To go over the measurements of each size, the switch itself, overall, from end to end, is going to give us a measurement of about 4-3/4" that does include the mounting location here with a pre-drilled mounting hole. It's going to stand at a height of about 7/8". The battery box is going to give us an overall width of about 6-1/4" to 6-1/2", somewhere in there that is including the mounting locations, the extension of the brackets here at the back. Overall height is going to give us a measurement of about 4" and then the overall depth is going to give us a measurement of about 4-1/2". That's going to do it for today's review of part number 50-85-313.

Breakaway system with built-in charger is designed to bring a trailer safely to a stop by activating its electric brakes should it become disconnected while being towed. Push-button tester lets you know if the rechargeable battery is fully charged.Website was very user friendly with good info. Order process was easy. Product arrived quickly. VERY GOOD experience 469594
Product arrived quickly and was as described. One feature I especially liked is the light indicating that the device is being charged when 7-way connector is plugged into the tow vehicle. Included installation instructions were same as on the etrailer website and were not very useful. Wiring diagrams for other than the breakaway device itself were difficult to decipher. The installation video on the etrailer website, however, was easy to follow and left nothing unanswered. 401598
Still working a designed, trailer parked for long periods, battery shows it’s holding a charge.
Smokymb - 07/04/2018I can only give this rating on the quality of the hardware because I never want to have to use it! Overall the product is well made with quality hardware components, a more than adequate sealed battery that came fully charged, and what appears to be 12AWG wiring where it needs to be to do the job the unit is intended for (lock the breaks in case of a breakaway). I bought this unit because I have a Tekonsha Brake Controller and I wanted to stay within the same product line. 194562
This was a great buy with the battery & charger included. If your main battery is dead this one keeps your breakaway switch active. You need this while transporting your trailer from your winter location to your summer storage area. 128692
Another easy to install and use product, total idiot prof to use will definitely buy another one if needed. 115492
Still working fine good product no Major corrosion

A top notch product that works well and is priced right. Thanks etrailer! 581639
I have received all my parts in a very timely manner. The product s were exactly what they were advertised as and the installation went well. Prices were very reasonable and was shipping. Hopkins 7 way molded tral. Conn. Trailer light kit part # I forgot #mcl86ab clearance lights #38656 junction box #50-85--313 tekonsha breakaway. 539363
Great product. Looks great. Fairly easy to install. If using a junction box with this product you need to remember to hook one of the leads from the break away switch to the black wire as described. The other wire hooks to the blue break wire. At first I hooked to the blue from my truck, the blue from this battery pack, and the blue going to my brakes. After several hours of trying to figure out the error it threw on my brake contoller in my truck I took it to a trailer place where they had to do some trouble shooting of their own. They found that the lead from the break away switch needed to be spliced into the blue wire going to my brakes after the junction box to make it work properly. It can't be on the same terminal as the battery pack. Other than this little issue it has been great, hopefully I never need to find out how well it works on a run-a-way trailer! 92166
works great, mounted very easy and connections were simple. good quality enclosure. 727810

The push to test Tekonsha break away system was a perfect replacement for my worn out system and was easy to install 683742
Easy to install, good straight forward instructions. 674669
Item arrived with battery leaking so I could not use. etrailer rep resolved the problem fast with a total refund. Note this was not a vendor, rather a supplier problem. I was completely satisfied. 648096
Great product. Great customer service from etrailer. I was easily able to install this product with information received with the item and from the etrailer website. Very satisfied and highly recommend. 647663
Simple to install. Works great. 639732
The plastic face plate on the top lid came off on the first one when I was washing off the trailer. It didn’t work after a little water got inside. So this replacement one, I put a bead of “shoe goo” around the edges so it doesn’t happen again. Other than that, it works well when testing it out. 636162
IT CAME QUICKLY, AND CUSTOMER SERVICE WAS HELPFUL MAKING SURE WE ORDERED EVERYTHING THAT WE NEEDED. 617558
I have a 2015 GMC Sierra 2500HD Diesel, towing a 2017 Pinnacle 36FBTS 5th. wheel. The Pinnacle has a standard drum braking system. On a long trip this year I cracked both rotors on my truck from over heating related to the Pinnacle's drum brakes failing to fully provide proper stopping. I decided no more, and after much review I replaced the factory drum brakes with the Kodiak Discbrake system. (my first time ever doing something like this) In addition, one of the key items for me was a way not to replace my on-board factory trailer brake controller, (did not want to use an aftermarket product, that would diminish the interior look ) thus I also added the control Adapter Module that enabled me to use the factory installed brake controller. With all this change I decided to also go ahead and add a separate brake away battery. Everything I just described are shown in the attached photos. I found eTrailer extremely helpful in answering questions, although I did not have a lot of questions since their online videos proved most helpful. All parts of the Kodiak system worked fantastic following a 2500 mile trip. The improved braking is superior, and I did not need to replace my on board controller, but continued to use it by installing the control adapter. The disc brake picture is one of the disc brakes that I examined following our trip...all in perfect shape with everything working great for the entire trip. 610894

Excellent product. Fast shipping. 603222
This is a great product. Makes the installation easier and I love the battery monitor feature. 601812
Nice kit at a great price. 598884
So far I think I have this thing figured out. The directions with the breakaway kit are different when you are using a hydraulic actuator. I was a little confused but figured it out. 592998
This is a well-made product and was quite easy to install. The directions made the wiring simple. I especially like the test button on the top of the case, which lets you easily check the battery without opening the case. The case is a durable plastic, which allows some flexibility if you need to add another hole or two to match your current mounting bolts. After 3 years of use, the battery and housing have held up fine. 584541

Timothy - 03/28/2019I’m very happy with everything that I purchased from the trailer and there will probably be a few more things that I will get this year keep up the good work thanks 481162
I installed the switch, but turned out I didn't need the battery. Switch works fine. 471560
The kit was all I needed to replace my old unit. I am happy with the quality of the components. I would have given it 5 stars but the wiring diagram was printed for an electrician not a DIY trailer owner. Thanks 458223
works correctly. green light every time I check it, yellow charging light when I hook up. Would buy this unit again.
John C - 12/10/2018Seems to be fine. 455487
