by:

This battery kit is a perfect replacement for the battery that was on my 16 ft trailer to operate the brakes, in case of trailer breakaway. The charging light comes on when connected to my Tacoma pickup truck, which keeps the battery charged. This is a great product, and I'm very pleased with it.



by:

Following the installation instructions made the work fairly straightforward. The hole pattern for the case was as-advertised, so it fit perfectly where the old kit was installed on the trailer rail.

Cant tell you. I sold the trailer with the boat!



by:

Would definitely purchase again! This is a good kit for setting up a break-away on your trailer. Make sure to mount it out of the way so that it doesn’t get impacted by any thing.



by:

It arrived a day early, and it was exactly what I ordered! Go figure. Now I can put this in my ancient horse trailer instead of stacking rocks in the yard.



by:

I am generally happy with Hopkins quality products. This one is one that I am very happy with. Quality is superbe.



by:

Very good product. Clear instructions made installation easy. Solved my wiring problem.



by:

Very easy to install and I feel it is made to last. I am very pleased with my purchase as well as the customer service provided by E trailer.



by:

Simple installation , wiring diagram on the top cover. Easy Peasy!!



by:

I bought these brake batteries when rewiring two old horse trailers. This is the third & fourth trailer I've rewired, so I'm pretty used to it by now. Everything about this product went together easily. Routing the wires on the trailer was another story, as usual.

I sold one trailer, but I've been using the other trailer infrequently for about a year now, and the brakes seem to be working quite well. I haven't had an occasion to test the breakaway battery out on the road, fortunately, but the little lights on the top indicate that it's maintaining a good charge, and the breakaway switch did lock up the brakes when I tested it in my shop.

BTW, I *love* pairing these with the Bargman coiled wiring plugs. They're so much nicer to use than straight wires.



by:

I really wanted a 9 ah setup to insure ample power but I could not find one that also had a push button test feature so I decided I would just mount two and configure them to work together. It uses two, dpdt switches to switch the units on and off line either independently or together. This gives me assurance of ample power and a backup to each other..
One thing I'm going to do is run a diode isolated circuit to the cold side of the breakaway switch to the l.e.d. Break lights so if the trailer ever did come lose, it will also apply the break lights. The two diodes will keep the tow vehicles breaklight power from back feeding into the actuator's emergency stop circuit.

Opened battery box and tabs that hold battery in place are broken

Oh no! I will have our Customer Service team contact you.

Product works well
Applies power to
the electrical brakes if the cord is pulled
Easy to put the cord back into the switch
Used on a homemade trailer
That was made to carry bale barns
(hay feeder for horses)



by:

This unit replaced the crusty 30 year old battery on my car trailer.
Easy installation if you do what I usually don’t. That is, read the instructions!!
The status LED charge indicator is a great feature.



by:

Parts looked good and a fair price. I'll buy here again



by:

Great product but wish it had better labeling and instructions for the wiring



by:

Easy install if you read and pay attention to the directions. This was installed with a new 7 pin plug and there are different wiring configurations between utility trailers and larger rv type trailers; so pay attention to what you are reading and wire according to your project.



by:

Thankfully I haven’t had to have an operational use of this. It was a straightforward installation and is easy to check the battery status. I would order this again, if needed.



by:

i purchased this product to replace the same unit i purchased 5 years ago. The previous unit had sundamage and the top readout was no longer readable , the cover hinged were broken. easy replacement and works great



by:

Fast shipping, pictures and items matched up to exactly what I needed. Thank You Again!



by:

Perfect fit quick delivery.



by:

While it was an easy fix, the wire length on the battery box is pathetic. The breakaway switch had long enough wires. If you get this, just run new wiring from the circuit board like I did.



by:

Clean and easy.



by:

Easily installed to replace the 13 year old unit



by:

My breakaway came very fast and at a good price. I use e trailer all the time because they have what I need and get it to me fast.



by:

Still working great

  • Do I Need a Breakaway Battery Charger for My Trailer
    You need an electric breakaway when you have electric brakes on your trailer. A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs. Hopkins Engager Breakaway Kit with Built-In Battery Charger # 20400 would provide you with everything you need for a single or tandem-axle trailer. The battery and breakaway switch mount to the trailer. The battery is charged through the 7-way connection from your vehicle....

  • Trailer Breakaway System Operation And Troubleshooting
    The brakes shouldn't necessarily lock up, but the brakes should quickly bring the trailer to a safe stop. The weight of the trailer shouldn't matter if the breakaway kit and the trailer brakes are working properly. All trailer from utility to RV with a much larger weight capacity than the 5,000 lbs you mentioned use breakaways like the Hopkins # 20400. If it isn't functioning to a safe level, there is a need to fix something. It may be a ground, it may be a brake magnet, it may be...

  • Parts Needed to Add Brakes to 1992 Coleman Arcadia Pop-Up Camper
    Based on your manual indicating 7" brakes it is probably a 2,000 lb axle. That should be a 4-bolt brake flange on the axle as well. Try checking your axle tag to see if you can verify this. The capacity may be listed, or it can be found with the serial number. You will need the following parts to add brakes: -Dexter Trailer Hub and Drum Assembly for 2,000-lb Axles - 7" - 5 on 4-1/2 # 8-257-5UC3 -Dexter Electric Trailer Brake Kit - 7" - Left and Right Hand Assemblies - - 2,000- to 2,200-lbs...

  • Electric Trailer Brakes Engaging
    Thanks for the nice words and all that information! It certainly isn't normal that your trailer brakes are engaging without a brake controller though there are a couple of reasons why this can happen. My guess is a wiring issue on the trailer where the wires are making contact and 12 volt power is getting through to the brakes. So I recommend going over the wiring from your brakes and tracing it to see if there is an issue there. If need be you can replace with 10 gauge wire # 10-1-1. Or...

    The first thing you will need to do in order to add brakes to your 2020 Karavan utility trailer is make sure you have a brake mounting flange. If you don't, you will need to take it to an axle shop and have a mounting flange installed. This will require identifying your axle. For example, if you have a 3,500 lb axle you would need the Brake Mounting Flange for 2-3/8" Round Axle # 4-35.

    Adding brakes to your 2004 Fleetwood Pecos Pop-Up Camper will require hub and drum assemblies, brake assemblies, 7-way wiring, and a breakaway kit. However, the first thing you need to do is check and see if you have a brake flange on the axle. If you do not have a brake flange, you will either need to weld one on or replace the axle. Either way you will need to identify the axle and capacity to do this. The best way is to check the axle tag. If you can send me or the axle manufacturer...

  • Electric-Over-Hydraulic Actuator and Breakaway Battery Kit Recommendations for 3,500 lb Trailer
    Happy 4th to you as well, Jerry! Since you already have your 2017 Toyota Tundra set up for electric brakes you just need to add an electric-over-hydraulic (EOH) actuator and the breakaway battery kit. Here is what I recommend for your application: - Actuator for Drum Brakes # HS381-8066 - Actuator for Disc Brakes # HS381-8067 - Breakaway Battery Kit # 20400 Attached are some review and installation videos for you to check out!

    The only modification needed on your F-350 to enable use of an electric-over-hydraulic trailer brake actuator like the Dexter # K71-650 (for drum brakes) or # K71-651 (for disc brakes) is installation of a trailer brake controller such as the Prodigy P3 # 90195.

    Hey Dan I can definitely help with all of this. The # e43SR Trailer Axle that you were looking at comes with electric drum brake assemblies.

Engager # 20099 is meant to be mounted on top of the frame with the LED indicator and test button facing up.

    In order to replace your axle you will need to know your current axle capacity.

Once you have this information you will be able to find a replacement, assuming one is available. Since you have square axles now and would be switching to a round axle you would also need new U-bolts. If you cannot find an axle with the same length and capacity the other option is to...

If you would like to send a photo so I can take a look, please do. To add electric brakes to a 3,500 lb axle (if that is what you have) you will also need a 4-bolt Brake Mounting Flange # 4-35, a Breakaway Kit such as # 20400, wiring for your trailer as well as a brake controller...
