Most Popular Solar Panels to Auxiliary Battery for Ford F-350 Super Duty

Thanks etrailer for bringing this product to the USA market. I found the REDARC chargt talked about on Australian “caravan” blogs before etrailer had it for sale and considered trying to buy it from an Australian vendor. I use the BCDC1225D to charge my 200 amp hour lithium battery in my truck camper. I have 350 watts of rooftop solar and ran 8gauge wiring from the truck battery through a bed mounted Andersen connector. The very compact size of the unit allowed me to tuck it away in a small space in my camper. I wired it up just as suggested in the instructions and it worked perfectly. I’m getting the full 25 amp charge that the solar panels will provide at midday and get the added benefit of being able to charge at the same rate while driving in the dark. The thing works great. Thanks again etrailer for bringing this product to the USA market

This unit has worked fine for me. Once wired up I can pretty much forget about it and know that it's charging my house battery whenever I start my vehicle. Probably more important is the automatic disconnection it makes from my starting battery & vehicles charging system when I shut down the vehicle. As well the convenience of adding a solar panel to the system to charge the house battery while the unit still AUTOMATICALLY chooses the best option to charge and disconnects anytime I shut down the vehicle. There are a LOT of different devices/ electronics to accomplish this but the Redarc seems to combine many features/connections in one convenient unit. I have not had the solar portion hooked up yet BUT my understanding is that when I get ready to do so I will NOT need to order a separate MPPT charge controller as that is a built in feature of the unit. These units are a bit pricy for up front cost but seems to provide a lot of features all in one compact unit with a fairly simple wire connection to get it up and charging.

This unit has performed as expected. My batteries are mounted inside a plywood box in the back of my van. All the connections for the Redarc are inside the box so it has a very clean install on the exterior of the box. The two DC switches in the picture allow me to disconnect the input line to the Redarc from the vehicle's electrical system and the second disconnects my Battle Born batteries from everything. I only shut off the system when I take it into the van dealership for maintenance, and that is only precautionary.

This thing is just great. It is rock solid in construction and function. Everywhere I go now in my Arctic Fox slide in and F350, bu two 100AH LiFePo4 batteries are charging at 45 amps along the way. The fact that the Redarc is weather proof allowed me to mount it outside under the camper skirt running my 4awg battery cables along the bottom of the camper right to it.

Pretty easy to install, works well.

This is a game changer. Charging 2 100 Ah batteries in 4 hrs or less of driving is really nice. For my style of travelling, I don't need anything else to keep my batteries charged.

Should come with something to secure to trailer (magnets, Velcro,?) It would also be nice to have description of what the indicator light are indicating

Amazing item, easy to install, and keeps the battery on my dump trailer topped off between use. I park in an area without power so helps ensure I don't have to charge the night before a use.

Purchased solar panel to keep my trailer battery fully charged, since it is not used frequently I do not want the battery to be low when it is needed. I have not yet mounted it and will put it in the tool box when using the trailer since the truck alternator will be charging when in use.

I have one on my dump trailer and one on my 5th wheel. I havent had any issues at all. Easy to install and works as described.
