Video Transcript for Hopkins Trailer Breakaway Kit Battery Charger Installation

Today on this enclosed trailer were going to install part number 20011 from Hopkins. This is their trailer breakaway kit battery charger. Right now, looking at our trailer the way its hooked up is that it does not have a battery charger. It has a 12 volt power lead coming off the towing vehicle going straight to the battery that will charge the battery, but over time that could overcharge the battery, especially on a long trip. Were going to install our battery charger. The first step is we will go ahead and locate the wiring that comes off the battery charge from the towing vehicle and we will hook that up to the black wire.

Next we will go ahead and take the red wire and we will hook that up to the battery on the trailer, that way the battery will be getting a charge. Now the blue wire coming off the charger will go out to our breakaway switch. You can use a variety of different connections. In this case we will be using wire nuts. Once our connections are made we can take our charger and tuck it in next to the battery.

With that, that will finish it for our install of part number 20011 from Hopkins on this enclosed trailer.

Trailer Breakaway Kit Battery Charger - 20011

Average Customer Rating:  4.8 out of 5 stars   (42 Customer Reviews)


by:

Great little electric brake battery charger. Easy install. Fast shipping and a great price. Thanks etrailer. Definitely buy from etrailer again.


Comments
After a year works like the day I installed it.
Eloi D - 05/11/2021


by:

I bought TR20048, and after about 2 years the charging circuit started malfunctioning. There are no replacement parts for TR20048. So I removed the original circuitry from the TR20048 and replaced it with 20011. 20011 does not have LED indicator lights, but it charges the battery without overcharging and is very inexpensive.




by:

Great product for horse trailers like mine whose manufacturer was too cheap to include. Easy install and wires are marked where they go. Fairly priced too.


Comments
Product working perfectly after 1 year. No complaints.

by:

Excellent experience and communication, great product and instructions




by:

It gives me peace of mind knowing that my trailer battery is being charged while I'm driving down the road on a trip since the trailer/battery sits most of the year. This item was easy to install. The harder part was the van wiring, connecting a wire to the van's trailer connection so that the charger thing could work.




by:

I just received it. Looks good, was delivered as promised.




by:

A simple low cost solution that is easy to install. Installation took about 20min. In my opinion every trailer from the factory should have these pre- installed but many don't and without one the small breakaway battery will charge at too high a rate and probably overcharge, both of which can shorten the life of the battery.




by:

great little battery charger fit into breakaway box just fine. I use it on a double axle utility trailer. It will keep trailer break away battery charged up




by:

Still working great - just checked battery voltage after being parked a few days: 12.90 on the SLA alarm-type battery, so it's certainly working.

Always forgot to maintain, or even check the last battery - have no idea when it actually died. Wiring in this regulator ensures that it will have a much better chance of actually working IF I ever need it to. Lets hope not. ;)




by:

Does not come with any instructions, so get the wire coding off the internet here.
Tiny, will be easy to mount in the battery box.




by:

I like your website its got everything I need for my trailers and will come back and order again. Couldn't find any of these products locally found everything on etrailer.com. Great site.




by:

It took about 5 minutes to install this charger. I can't understand why trailers don't come with these from the manufacturer.

Etrailer is great, and we'll be doing more business in the future. I have a few trailers, and I can't imagine needing anything that Etrailer doesn't carry.




by:

Olivia M . was great. She is a great asset to your business.




by:

Easy installation. Durable connectors. Has worked great. Would highly recommend this product.




by:

I have installed the battery charger, and it seems to be working fine. I was impressed with the quick delivery and good packing.




by:

GREAT SERVICE AND SUPER PRICE. THANKS ETRAILER




by:

Received on time, installed easily, only time will tell if it dies its job. Thank you




by:

Installed easily with instructions provided.




by:

Inexpensive solution to ensure your battery doesn't overcharge.

Good product at a good price. Excellent shipping price with fast delivery.

  • Battery Charger for a Trailer Breakaway Kit Battery
    Generally a breakaway kit is installed mounting the battery to the frame but it doesn't have to be. We carry a few different chargers separate from the kits themselves and I've linked our selection for you. The most popular of the chargers if the Hopkins # 20011. To install the Hopkins charger the black wire connects to the power coming from the vehicle battery, the red wire to the breakaway kit's battery, and the blue to the pin. I've also linked a video for you.

  • Will the Hopkins Trailer Breakaway Battery Charger Work for an Auxiliary Battery on a Trailer
    Yes, you can use the Hopkins Trailer Breakaway Kit Battery Charger, # 20011, with the motorcycle battery on your motorcycle trailer. Like you said, you would simply tie-off the blue wire since it will not be used. This charger will maintain the charge on your battery and even provide a small charge when you are connected to the tow vehicle. The benefit of adding this charger to your battery is that the charger will stop sending power to the battery once the battery is fully charged. Overcharging...

  • Installation Direction For Trailer Breakaway Kit Battery Charger, part # 20011 on a 2013 GMC Sierra
    When installing the Hopkins Trailer Breakaway Kit # 20011, the black, red and blue wire are attached with the following procedure. The black wire is connected to the black wire in the battery box on the trailer. The red wire is hooked to the positive post (by itself) of the battery on the trailer and the blue wire is spliced to the blue wire from the breakaway switch. I have attached a FAQ article covering breakaway kit installations as well as a brief installation video. I can help...

  • Hopkins Trailer Breakaway Battery Charger Gets Hot
    Battery chargers do get hot, especially if plugged in for long periods of time. If it is so hot that you can't even touch it then that would be a problem, a short somewhere either with the wiring or internal on the charger. On the wiring make sure there are no pinched, frayed or damaged wires and fix as needed. Make sure that the black wire is connected to the 12 volt circuit coming from the vehicle, red is connected to the positive breakaway battery terminal, and blue is connected to the...

  • Wiring Functions of Hopkins Trailer Breakaway Kit Battery Charger 20011
    Trailer Breakaway Kit Battery Charger # 20011 is indeed a charger. When using it the black wire connects to the 12 volt power circuit coming from the tow vehicle. The Red wire connects to the breakaway battery on the trailer. The blue wire connects to the breakaway switch. I have linked a video that shows installation of this charger to better illustrate how it installs.

  • How Do Trailer Batteries Normally Get Charged When Being Towed
    What most people do to put a maintenance charge on a deep cell battery like yours that is on a trailer is to run a 10 gauge wire from the 12 volt accessory circuit on the 7-way directly to the positive post of the battery. A battery of your size can only have a maintenance charge put on it through the trailer connector though since the wire gauge is pretty small. The silver lining to this is that you would never have to worry about the battery getting over-charged.

  • When Running Battery Charge Wire on Trailer is a Ground Wire Needed as Well
    If you are running a 12 volt power line to the battery of your trailer there would be no need to run a separate ground wire. You are charging the battery of the trailer and not operating an accessory with that line so it would not need to have a ground to the battery as well. Similar to an alternator charge wire on a vehicle. There isn't a ground wire ran from the alternator to the battery as well.

  • Trailer Breakaway Kit Battery Charger Wire Functions
    Each of the wires on the Trailer Breakaway Kit Battery Charger, part # 20011, have a specific function, but none of them are grounding. The black wire goes to your vehicle battery, the red wire goes to your trailer breakaway battery, and the blue wire goes to your break-away switch.

  • Trailer Breakaway Kit Battery Charger 20011 Operating Temps, Current Draw, Type of Charging
    I spoke with a technical adviser at Hopkins, the maker of this charger and he said the safe operating temperatures for this Trailer Breakaway Kit Battery Charger, part # 20011, is between -20 degrees and 140 degrees Fahrenheit. The max current draw is 5 amps and uses a trickle charger, yet shuts down when the charger is full.

  • Need for Charger on Battery on Trailer Break-Away System
    I strongly recommend using the charger. The charger, like part # 20011 will protect the break away battery from overcharging or charging too quickly. The charger is a small investment, and it is easy to install. If you should decide that you are interested in the charger, it would wire as follows: the black wire would connect to the 12-volt supply circuit off of the 7-way, the red wire attaches to the positive terminal of the break away battery, and the blue wire connects to the break...

  • Will the Trailer Break Away Battery Charger Work with a 12 Volt 5 Amp Recahrgeable Breakaway Battery
    I spoke with my contact at Hopkins and the Trailer Breakaway Kit Battery Charger, item # 20011, should work with your 12 volt, 5 amp, rechargeable breakaway battery. We have a detailed description on how to install a breakaway kit with charger in the second section of our Breakaway Installation page (see link).

  • Where Do Wires of Hopkins Breakaway Charger # 20011 Go To
    For the breakaway batter charger part # 20011 that you referenced the black wire would get connected to the vehicle battery to get the charge, the red wire is the wire that gets connected to the battery in the break-away kit on the trailer, and the blue wire is the wire that gets connected to the actual break-away switch. I attached an install video link for this for you to check out as well.

  • Can Trailer Breakaway Kit Battery Charger be Used With Battery on Trailer
    Yes, you can use the Trailer Breakaway Kit Battery Charger # 20011 from the main trailer battery. You will not want to attach the red wire to the switch battery positive and blue to the negative. To install, what you need to do is connect the black wire on the charger to the positive side of your trailer's 12 volt battery that you mentioned is kept in a charged state by the solar panel. The red wire on this charger will connect to the battery in the breakaway kit and the blue wire is connected...

  • Function of Blue Wire on Hopkins Breakaway Kit Battery Charger # 20011
    The blue wire from the Hopkins Breakaway Kit Battery Charger # 20011 is what goes to the actual breakaway switch. The black wire goes to the 12V power circuit and the red wire connects to the breakaway battery on the trailer. I have attached a sample installation video that you can also follow along with.

  • Can Battery Ban, on Trailer Split Up for Breakaway and Trailer Accessories
    I think your plan would work just fine. You'll need to make sure the breakaway battery though is charged at all times in the event of a trailer disconnect. Typically charging it off of the tow vehicle is adequate for this. For a breakaway battery charger we have the part # 20011 that gets wired to the breakaway battery from the tow vehicle wiring.

    Yes, the Hopkins breakaway battery charger part # 20011 that you referenced can charge a 3.5 amp AGM battery.

  • How to Wire the Trailer Breakaway Kit Battery Charger Part # 20011
    To answer your question yes, the Trailer Breakaway Kit Battery Charger part # 20011 can be used to charge your breakaway battery while drawing power from the 12 volt auxiliary battery on your trailer. However, most local and state regulations require that the breakaway battery receive a charge from a battery not mounted on the trailer therefore, I recommend using the Trailer Breakaway Kit Battery Charger part # 20011 to pull power from the vehicle's battery via the 12 volt pin on the 7-way...

  • Vampire Draw on Trailer Breakaway Kit Battery Charger
    There is not a breakaway kit battery charger, including the Hopkins # 20011 that will eliminate vampire draw completely. I do strongly recommend taking a look at the help article I added on trailer breakaway kit installation. Going by this should help you maintain your battery charge if by some chance you have not wired yours the same way.

  • How To Install Hopkins Battery Charger For BreakAway Switch 20011
    The Trailer Breakaway Kit Battery Charger # 20011 is used to charge the breakaway battery on a trailer. The black wire connects to the tow vehicle's battery to get 12V, the red wire connects to the positive terminal on the trailer's breakaway battery, and the blue wire connects to the breakaway switch. I made a simplified wiring diagram to show you how it gets wired in; I also attached a demonstration video for you.

  • Can Trailer Breakaway Kit Battery Charger 20011 be Used with Dexter EOH
    To wire in the Trailer Breakaway Kit Battery Charger # 20011 you'd run the black wire to the 12 volt accessory circuit of the trailer wiring, the red wire to the battery in the breakaway switch and the blue wire breakaway switch. The 12 volt accessory circuit is probably already ran to the trailer's battery but it's okay for it to also run to this battery charger as well by adding a splice to it.

  • Can a Trailer Breakaway System be Run off of Existing Trailer Battery
    A breakaway kit can be wired in one of two ways to the trailer brake system. The first way would be to use the Engager Trailer BreakAway Kit with Charger and Tester, item # 20099 , and splice off of the power wire that maintains the trailer's battery on the trailer to charge the battery included in the kit (see instructions). This is the recommended method of installing a breakaway kit since many states require that a breakaway kit with separate power supply be used. The second option,...

  • Need 8 Inch Wheel with 4 on 4 Bolt Pattern and 3 Inch Backspacing for 1968 Apache Tent Trailer
    The Dexstar Steel Trailer Wheel, # AM20011, is 5-3/8 inches wide from bead to bead. Since it has a zero offset, half of that would be 2-11/16 inches. You would then add 1/2 inch for the lip, making it 3-3/16 inches. Just 3/16 inches wider than the 3 inch back spacing you are looking for. This is probably going to be the closest match.

  • Can a Trailer Break Away Battery be Charged from the 7-Way Trailer Connector
    If you have a break away kit that does not include a charger, you can provide a charge to the battery using the 12 volt circuit or auxiliary circuit from the vehicle 7-Way trailer connector. However, using the 7-Way can overcharge a break away battery. It would better to add a charger designed for a break away battery like # 20011.
