DC-DC Charger

I installed a Renogy 20amp DC to DC charger to charge my aux. 12V Deep Cycle battery.

Some good information buried in a terribly rambling video. Best to you.

Rudy, 5/16-24 nuts will go on a 5/16-18 bolt with a good impact and a few cold ones. lol

You don’t need the panel switch in the cab if you have the perks selector switch👀😎🇺🇸

Few things: the prelabeled switches can be replaced, they are just plastic covers that pop off and you can order different labeled or colored replacements. Second, you can change the position of the F44DA fuse position to the F40DA fuses for "RAP" retained accessory power and the 12V and USBs will function with the truck off. Third, the bullshit adaptive charging can be overridden with turning the headlights on or engaging tow/haul mode.

I bought one of theses, the 20A Renogy DC-DC on board battery charger, model DCC1212-20. I placed a 30A breaker on the pos line from the starter battery to the device, as per the instructions. However, the breaker keeps flipping. I changed it out, but the new one keeps flipping. So this device is not charging my house battery because of this. I have a 150 amp alternator. Before I bought the device, I called Renogy and was told to buy the 20A device. Now, the Renogy customer service number hangs up after it plays the initial introduction message.  

What do you recommend?

Always leads to government regulation screwing up every thing.
