Video Transcript for Review of Pro Series Trailer Breakaway Kit - Kit with Charger - 50-85-315

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this Reese Towpower Push to-Test Breakaway Kit with the Integrated Charger. Now, this breakaway system will activate your trailer's electric brakes if your trailer happens to disconnect from your tow vehicle. It does include this 12-volt rechargeable battery in the box with the charger and the breakaway switch with the cable.Now, this is a push-to-test battery feature on the top here, which will offer fast and easy battery testing. This test button right here, the blue button, it says push to test, this will indicate with LED lights if it will display the battery status.

So right now if I push it, I don't know if you can see it, but I push it and you can see the green button over here is lighting up. The green means that it's charged, so it's 12.8 volts or higher right now. If I pushed it and it showed yellow, that would mean it would be charging. And then if I pushed and it showed red, that would mean low battery and it needs to be charged.It does have a built-in charger which will automatically refuel the battery. It has a float mode which will maintain voltage while you tow without overcharging to prolong battery life and then a smart adjust feature which automatically switched to the float mode when the battery is fully charged.

This is a top loading case. You can see right here, you just push in on it. I'm going to pop it open for you. There you go. If you push it in, it'll pop open.

There's your battery and your connections all made and then when you close it, it'll snap shut. If you notice, it's a nice polymer construction, protects the battery from moisture and debris.Now the mounting hardware to install this is not included and this is a lockable lid. You can see the holes line up here. You could actually put a padlock through there to prevent theft. The padlock we do sell separately.

Also on top of the lid, they do have the wiring code. It shows you that to white wires . There's three wires that need to be connected. The white wire goes to ground, the black is to the battery for power and the blue goes to one of the wires on the breakaway switch. Now this breakaway switch this will install on your trailer's frame. Drilling is required to install this.You can see this cable here. This will attach to your tow vehicle and what happens in a runaway situation where it comes disconnected, it would pull this pin out which would activate the brakes to stop the trailer. There are two black wires on this. One goes to the blue wire on the battery box and the one connects to the electric brake trailer feed. The wire feed length on these is about 7-1/2" and the cable length, if I undid that, it would go out to about 4' long. Now, this is DOT, Department of Transportation compliant application. Application - this is for single, tandem and triple axle trailers with electric brakes. The battery capacity in this is 5 amp hours.Give you a few dimensions on this, on the battery box itself. Overall length, top is about the widest. It's 5-1/2". Width on it, 4-1/4" wide and the overall height is about 4-1/4" tall. The mounting holes on the back here that should mount to your trailer, distance between those center-to-center horizontally is about 5-5/8". And vertically center-to-center is right about 1". It does come with a nice set of detailed instructions that'll describe how everything hooks up and how it operates. But that should do it for the review on the Reese Towpower Push-to-Test Breakaway Kit with the Integrated Charger.

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.

Battery was fully charged when received, but put it on a float charger for a day just to be sure. Nice kit, easy to check the charge using the button and LED indicator on the top of the battery box. Install was easy (deciphering the rats nest of wiring in my cargo trailer was another story - thanks Pace America!). Should work well going forward and will be easy to check the charge before trips, like the fact that the controller will handle charging the battery while underway on the road as well.

Both Products arrived in a timely matter. Packaged to be shipped safely and received in excellent condition. Extremely simple to install in about 30 minutes time. Highly recommend the products and etrailer .com to everyone who asks me where to get trailering products and equipment needed to tow their trailers safely.

The breakaway kit is exceptionally well made and priced far below most other suppliers of trailer parts.

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.

So far so good, i trust it to be a solid unit should i ever have a breakaway.

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.

Excellent!!!! Good prices, quality products and outstanding customer service. I placed my order on a Sunday, and got an email that evening that one of my items was on back order. They suggested an alternate item in stock in case I didn’t want to wait a week for the back ordered item. Customer service doesn’t get any better than that. Thank you!

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"



- 50-85-315
by:

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.



- 50-85-315
by:

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.

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.

Ask the Experts about this Pro Series Trailer Breakaway Kit

  • Breakaway Kit Requirement for Electric Trailer Brakes
    An Electric Breakaway Kit safety system is required in most states for trailers weighing more than 3,000 lbs. These kits will require a 12V battery and in most models a battery charger is integrated. Although it is not required to have that charger, it makes maintaining that system a lot easier than using a separate charger like # 329-GENM1 prior to each trip as that battery will loose charge over time. Our most popular kit and the one I recommend most is the Hopkins Engager Push-To-Test...

  • Can Breakaway Battery Be Submerged on Boat Trailer
    The battery/battery box for the Pro Series Breakaway Kit # 50-85-315 that you referenced (along with most other units) is weatherproof meaning it's designed to be mounted outside and can handle exposure to rain and splashes but it's not waterproof. Because of this I don't recommend actually submerging this or any other breakaway battery for even a short period of time. I know it will mean moving it to a less convenient location but I highly recommend mounting the battery in a higher...

    The breakaway cable assembly that is part of the Pro Series Breakaway Kit # 50-85-315 will mount to the front of your trailer tongue so that the vehicle end of the cable can reach to the safety chain hook on the tow vehicle. If you click on the link provided you can see the entire installation process for this kit on a goose neck trailer. Even if your trailer is a different type the installation steps are the same.

    I recommend you attach Tow Ready Trailer Break Away Kit, # 50-85-315, to your vehicle to a tie down point in the bed of your truck. You could also use a stake pocket tie down and attach the cable to it. Or you could run the cable down to the safety chain loop on the bumper hitch if your vehicle is so equipped. Finally, you could attach the cable to the rails installed in the bed of the truck. The thing to remember is that the place the cable is attached to needs to be strong enough that,...

  • Can Trailer Breakaway Kit Use Battery of Trailer
    DOT really will only care that the breakaway system battery will be capable of holding the trailer brakes fully engaged for at least 15 minutes at any given time. It's wiser to use a dedicated battery for this so that you don't deplete the main trailer battery with other accessories and then when needed it not be able to fulfill it's duties to stop the trailer. I'd recommend using a kit like the part # 50-85-315 that you referenced which includes a dedicated battery.

  • Where Does the Cable for the Break Away Switch Attach on the Tow Vehicle
    The cable loop for the breakaway switch in the Trailer Break Away Kit With Built-In Tester and Battery Charger, # 50-85-315, does not attach to the ball. Run the pin through a safety chain loop on the hitch. Pass it through the loop on the other end of the cable, and then plug it in to the break away switch.

    Test the 12 volt power wire that feeds the charging circuit for the breakaway kit part # 50-85-315 that you have installed on your trailer with a circuit tester like part # PTW2993. You should be getting 12 volts running into the battery box that will be providing the battery with a maintenance charge. You can also test the wiring leading to the battery from the lid with it disconnected from the battery to see if there is voltage there. If so, then the lid of the box must be defective...

  • Can a Trailer Be Pulled With a Faulty Breakaway System
    The trailer breakaway's are required in most states so I cannot advise for you to continue traveling without having the system repaired or replaced. It sounds like you have already identified the culprit (shorted wire) so what I recommend is just ordering a new system that way you can get it installed and hit the road again as soon as possible. The Pro Series Push to Test Breakaway Kit pprt # 50-85-315 is what I recommend for this because it is cost effective and easy to install. That said,...

  • When Would a Trailer Break Away Kit Be Required By Law
    Many states in the U.S. and provinces in Canada require break away kit. In order to determine the specifics for where you live and where you plan to travel, you can check with the state and federal departments of transportation for the area. Specific weights or trailer types may change from state to state, so it is important to check for every state in which you plan to be towing. A break away kit is just a good idea in general, whether it is required or not. It is a fairly simple system....

  • Length Of Safety Cable on Trailer Breakaway System Recommendation
    The best length for the cable of a breakaway system like the Tow Ready Trailer Break Away Kit # 50-85-315 that you referenced will be slightly longer than the safety chains. The breakaway cable should be longer than the safety chains according to RVIA Recreational Vehicle Industry Association. This will activate the brakes in the event you lose the trailer connection and the safety chains fail.

  • Trailer Brakes Work with Break Away System But Not with Brake Controller
    It sounds like the brake controller might need to be reset or the wiring from the vehicle side to the break away system needs to be examined. Try adjusting the power output of the controller. If that does not work you can test the controller itself using a circuit tester like # 40376 if needed. Sever the blue wire a few inches from the back of the controller and use the circuit tester to test the end coming from the controller while applying the manual override. If it does not show power...

  • Recommendation for Attaching a Trailer Breakaway Pull Pin Cable to Tow Vehicle
    Since breakaway pull pins require a pretty decent amount of force for them to get removed from a breakaway switch I would not recommend running the cable of the switch to a license plate bracket. Many people just put the cable through the safety chain loop on the hitch and then run the pin through the small loop in the end of the cable. This secures the cable to the hitch and no other parts are needed. In this configuration you need to mount the switch close enough to the coupler to...

  • Do Trailer Breakaway Systems Usually Power from Separate Trailer Battery
    Typically breakaway systems on trailers like yours will be powered from a separate smaller battery than the two larger ones you have on your trailer. You can trace the wiring of the switch back to see where it ends, but typically the breakaway system is in a box that is somewhat near the nose of the trailer. I attached a chart that shows how a breakaway system usually wires up as well. I also attached a help article on trailer breakaway systems for you to check out as well.

  • Brake Controller Does Not Detect Trailer when Breakaway System is Connected
    The most common issue with breakaway systems occurs because of the wiring. They do not always make it as straight forward as it could be. Starting from the trailer side connector the brake output wire will go to the brakes and to the breakaway switch. The other wire from the switch will go to the brake output wire on the breakaway battery. The power wire to charge the breakaway battery will connect to the 12 volt wire from the trailer connector. And the battery ground wire should be...

  • Troubleshooting Trailer Brakes that Are Activating but Not Stopping Trailer
    Sounds like you installed new brakes and they aren't wanting to grab and stop your trailer. Most likely you just need to adjust the assemblies so that they will actually grab. If they are self-adjusting brakes all you would need to do is make several brake applications with the trailer moving and they will set themselves. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. I also attached a help article...

  • Do All Trailers with Electric Brakes have to have a Breakaway System
    No, but your local and state laws may require one. You will need to check anywhere you will be towing the trailer to determine if a breakaway system is required by law. They are also just a good idea in general because they will stop a run away trailer should it get disconnected from the tow vehicle. We have several different breakaway options which I have linked to the right. I have also included a link to our help article on breakaway systems for you.

  • Parts and Installation of Trailer Breakaway Systems
    Yes, a towed trailer that has brakes must also have a functioning breakaway switch/battery system so that in the event of an accidental uncoupling of the vehicle and trailer the brakes on the trailer will receive direct 12V power from the breakaway battery to stop the trailer. We do sell replacement switches like # 2005-P, complete kits like the item # 50-85-315 that you referenced and replacement batteries like # C52023.

    It sounds like you have a charge line ran from the RV's battery to the trailer's battery. If this is the case then yes, you will need a current limiter (circuit breaker) in between the two in order to prevent any spikes that could in turn damage either battery. In the charge line kits we offer like the Roadmaster Battery Charge Line Kit part # RM-156-25, they come with a 15 amp circuit breaker so that is what I recommend you use. However, this battery charge line is only going to provide...

This is shown as the letter A in the attached photo. If something were to fail on the breakaway system then it would more than likely be the switch, not the pin. Since you said you smelled burning I would replace this anyhow with part # 2005-P which also comes with a new pin. With that being said, I suspect that...

  • Troubleshooting Trailer Breakaway Switch Where Wiring Causes Light to be Yellow all the Time
    I believe the problem is the connection of the switch on your breakaway. You said you went from blue brake output on the trailer to the blue wire of the switch and then on the other side of the switch you went to a black wire. You should have went to the blue wire of the battery box. The black wire of the battery box goes to the 12 volt power of the 7-way which is typically red.

  • What are the DOT Requirements for Trailer Breakaway Systems for Miltary Trailers
    I can certainly help. You will want to look at DOT/FMCSA regulation 393.43, specifically paragraph (d). This regulation should have everything that you need for what the Navy requires. In general, a breakaway system needs to be sufficient enough to apply the trailer brakes on fully for at least 15 minutes.

  • Breakaway System Kept Trailer Brakes On and Melted Wiring
    The way that a breakaway system for electric brakes works is when that pin is pulled it completes the circuit between the breakaway battery and the brakes. They have to stay on full for at least 15 minutes to be legal. But there is nothing stopping the brakes from staying on after that 15 minutes is up. Usually breakaway batteries are 5 amp hour rated. For 10 and 12 inch brakes each magnet draws between 3.2 and 4 amps. So if you have 4 brake assemblies that would be 12.8 to 16 amps....

  • Should Charge Light Stay Lit on Tow Ready Breakaway System when Disconnected from Tow Vehicle
    No, the charging light on the Tow Ready breakaway system should turn off if it is not getting a charge from the vehicle. If it stays lit up that could indicate a short somewhere that is drawing power. It could be due to corrosion in the trailer side connector. Make sure the trailer side connector is clean and free of corrosion inside and out. Check all connections for any loose or pinched wires/connections or frayed wires that might be touching bare metal. It could also be a ground...

  • Dead Batteries from Accidental Tripping of Trailer Break Away
    Yes, it is indeed likely that your trailer breakaway batteries were depleted from the accidental tripping of the breakaway switch (but good for you for doing the yard work!). If your main trailer batteries have a charge line to feed the breakaway battery then they could have been depleted as well. Breakaway batteries are required to be able to apply full braking power (in the event of a disconnect) for about 15 minutes; this may vary slightly depending on the particular system and the number...
