...You would not be able to charge your battery through the wiring on your 4-way trailer connector. Since your truck has a 7-way connector, you could maintain the power to the battery but not charge it...

You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7-way. The 1:00 position of your 7-way carries this circuit. You would just need to run a length of 10 gauge wire like part #10-1-1 (sold by the foot),…

For a 12,000 lb. electric car trailer winch like the Bulldog Winch Trailer Winch part #BDW10040, I recommend a standard 12 volt lead acid battery rated up to at least 650 cold cranking amps (CCA). As long as the battery is rated up to 650 CCA then…

Since your vehicle does have a smart alternator you do need to run a wire from the Redarc #RED96FR to the ignition. I also attached a diagram that shows how this installs on a Lithium setup like you have.

I've contacted Brightway, who forwarded me a copy of the instructions they include with the #BRW77FR switch mode charger. I've provided a clip showing the instructions for you.

Hi Frank, You absolutely can have both the Bright Way Switch Mode Battery Charger #BRW77FR and Bright Way Solar Battery Charger #BRW54FR connected and charging the battery at the same time. They both read the battery's charge level and adjust the…

Most if not all trailer wiring harnesses/connectors use larger wires for the 12 volt and ground circuits compared to the other circuits (lights). The sockets themselves don't have an amperage rating so you will go by the draw of the things…

Hey Greg, thanks for reaching out to us! Hopefully I can help you get all of this figured out so you can seamlessly keep your refrigerator battery charged up. It sounds like you're needing the Redarc In-Vehicle BCDC Trailer Battery Charger…

The Redarc In-Vehicle BCDC Battery Charger #RED96FR would function if connected to the 12 volt accessory circuit of your trailer wiring but it's not going to provide as much of a charge compared to if it was connected directly to your truck…

For a quick connect/disconnect style of wiring connector to connect the blue wire of the Redarc In-Vehicle BCDC Battery Charger #RED96FR to trailer wiring a single bullet style connector would be really easy to use and effective. We don't carry…

Hey Gary, so a charger like the NOCO Genius Multi Bank Smart Charger part #NOC24FR would work great to keep both of your batteries topped off and charged when in storage as this was designed for charging two batteries.

So smart alternators are one that typically have a lower voltage charge when the vehicle is accelerating and then a drastically higher voltage when the vehicle is coasting. This is a way to minimize the load on the engine when needing the power of…
