Hi Gang: We spotted this VW camper at our local county park. Carl.

Dave, that behavior is for a lead acid or AGM battery, right?? I believe a Lifepo4 battery, which Bob is thinking of installing, will pull the max 20 amps for the majority of the charging time.

Good discussion! One more thought to add: keep in mind that when a 20 amp DC-DC converter/charger is first engaged, its charge current to a partially discharged camper battery is nearly 20 amps

While looking to see if a bargman connector exists that handles bigger wire, i ran across the following.? It might be better than squeezing a fat w8re into a

Two comments on that: A wire smaller than what renogy recommends can handle the current the dc charger encounters.? But when using a smaller wire, the voltage drop is more, so the dc charger has to

Jean-Francois,? I also have a new Highlander, although not a hybrid.? Could you please tell me how you found the ignition no 2 fuse and what type of add a circuit connector you used.? If you don't

Steve, you may be right about sticking with a 20 amp charger to be on the safe side. ? But, the interesting thing I have noticed when looking for relays is that even the ones rated for 30-40 amps

The most restrictive requirements are in the dc charger manual.? Search for "renogy dc charger manual" and you'll find the pdf.

Bob, the dc charger pulls up to 50% more current on the input side than it puts out on the output side.? So a 30 amp dc charger can pull 45 amps from the TV, and your harness rated at 30 amps won't

Eugene, Please provide the URL for this chart. Larry

Be aware, that 10 gauge wire might not be big enough depending on the length of the run of wire. The greater amount of current that you will want to draw from your DC to DC the greater potential for

That is what I did in my past 2 vehicle. On the Venza (2009) there was a accessory +12V (cigar lighter plug) in the back. That one is ON on accessories, so it is on when the engine is running, off

Thanks again, Dave.? Your solution sounds like maybe the best way to do this type or set-up.? I was thinking, however, of using a 30 amp DC-DC charger as I have a 10 gauge wire coming from the

Every TV has at least one circuit that is only hot when the ignition is on. You can find these circuits within the fuse boxes that all modern vehicles have. Then just tap onto one of these

I ran into this same dilemma when I installed my DC-DC converter/charger, so I ran 8awg wiring from the TV start battery positive (AND negative too), through a 50 amp fuse and an ignition switched

Bob, I think the point that's being missed here is that one wire can be connected to 2 locations.? So if the power wire from the TV to the trailer shuts off when the TV engine shuts off, you can

Dave, this sounds like a great idea, but just wondering what you wired the relay to so it would turn off with the engine.? I imagine it would be necessary to find a circuit that is only hot with the

I've mentioned this before, so let me be clear: with the Renogy DC-DC converter/charger, the trigger wire does NOT need to be connected via a separate wire to the TV ignition! Just wire it to the

Actually, it is legal to tow with propane on in all states.? Its only illegal in some tunnels and on ferries. I saw a survey that said 70% of RVs tow with propane on, because its so difficult to get
