RV Lithium Battery Upgrade / Conversion for Newbies! | Renogy LiFePO4

In this episode: Jay explains all of the steps to plan an RV lithium battery upgrade! In the process, we convert our travel trailer from one lead acid battery to a bank of two 100Ah lithium (LiFePO4) batteries from Renogy. This will greatly increase our boondocking capability, and prepare the rig to add more charging sources, including solar panels and a wire from the truck’s alternator.

Be sure to check out the circuit diagram and cost overview on our website:

Thanks for your support!

I'm doing this to my Airstream in the off season. Thanks folks for the videos and I'm a new subscriber!

[tomlee]

great video. I have an off grid home with lead acids that I'm going to upgrade in a couple of years. Although I'm not a complete novice, I really appreciated the balanced level of detail on your experience with this video. No overly macho tech talk and not overly simplistic either. Lots of parallel concepts between your application and mine. Thanks!

"hook everything up", yes a bench test, what a great way to see how all the components are wired forward through it.

Great video! I bought the same Renogy battery and currently installing solar to my RV. This video will help me with the install.

Great Home A Roam How-To! Let the longer boondocking trips begin!

[itsme.rainilee]

Another great how-to from you guys--even though it LOOKS intimidating, this video makes it a little less intimidating! Though we aren't personally in need of this kind of upgrade info ATM, it's so great to know that there is a very informative explanation on how to do this! You guys are doing great stuff for all of us newbies! Part 2 should be interesting... "MORE POWER!!!" 😂👍

Way to go! We boondock all the time! Hopefully we'll see ya out there someday!

[ChrisAndEmilie]

I like your simple breakdown for calculating power needs. I assume that fan was noisy because it wasn't mounted but you might want to look at a bigger one as they tend to run a bit quieter!

[matk]

Cool and helpful video. I'm assuming you can just use a standard charge controller like the renogy rover elite for a lithium battery if only charging with a solar panel and not with shore power or from the 7 pin plug on tow vehicle

[tenara]

Where is your solar video that hooks that into the lithium bats?

[dougorlando]

This appears to be a complex "do it yourself" project. Did you consider getting bids to have a professional install it all, and what did you calculate you saved by doing it yourself? Personally, I don't have the skill or confidence to do all this myself, so you guys once again amazed me. You are both awesome!

[easydiy]

New subbie. Wow Renogy everything huh. I like their compact panels. That CC looks pretty neat. Great video 👍

[GimpyCamper]

This is a very thorough video. Great job. Welcome to the Youtube community FB group as well... BTW... I always cut my hair when we are camping now! lol

[mikep.]

Hello there. Great video and circuit diagram, i have a couple of questions though, would it be possible to see a picture of your full setup as you have it in the room? That would make the diagram read much easier and also is it possible not to install an inverter now and add it later?

[locopixel]

Just a correction. That renogy charge controller does DC-DC charging and solar panels but it doesn't look like it does shore power charging like you mentioned in the video. It would sure be nice to see one unit do all 3 but I can't seem to find one.

[JBMizz]

When you hooked up your old converter directly to the alternator charging post on the Renogy charge controller, which output wire from the converter did you use? Mine has three—red, white, and black that were connected to the old battery +, old battery -, and old fuse box respectively. Not sure if I should use the red or the black to go into the Renogy DC50. Any ideas?

[ric]

Hi, Thanks for valuable information. Please advise what amp of ANL fuse for each spot (between battery disconnection and battery, inverter and battery and battery disconnection, ac power and controller. your reply will be highly appreciated.

[jerrydaminato]

Excellent! We have to be concerned with our dual AGM's as we use an 80 watt CPAP at night. We don't boon dock enough to justify Lithium but next batteries maybe... Currently have 1000 Jackery (and a Generator) which makes a huge difference. So we're good for 1-2 overnights. Renogy is A1.

[DeanMCole]

I checked out your schematic and shopping list. It appears you’ll be connecting both the 12 V coming from your tow vehicle and the 12 V coming from your trailer‘s converter to the same input lug on the DC to DC converter using a 1-2-Both-Off disconnect switch. Is that correct? If so, can it be safely ran in the both position, or are there backfeed concerns using that switch setting? By the way, thanks for the great video!
