I'm going thru same thing with 8955, I reduced the wire length to 5'. Helped a lot with amps but still in LA mode. Getting full 55 amps when charging now. I emailed WFCO for a jumper hopefully I will get one. Great video, thanks for sharing!

Ayup, running into this b.s. with a WFCO WF-8955-AD. My camper has 8 gauge battery wire, so there's a large voltage drop from the WFCO to the Lithium battery. In reading forums, it looks like the WFCO never goes into Bulk mode as a result, and, obviously, the "AD" doesn't do the right thing. This is a HUGE failure on the part of WFCO and the RV manufacturers, as it renders the WFCO charger impotent -- and it breaks this "Auto-Detect" "feature." (As an aside...I had another thought as well: The voltage coming back out of the battery to the power distribution center would also drop in voltage. How does that affect the 12V items in the RV? And if you upgrade the wiring, what happens when the full Lithium battery voltage is applied to the stuff in your camper? It "should" be able to handle it, but...) I made my own jumper to get the WFCO into Lithium mode. I read it's a 1K resistor. Do you think you can Ohm yours out and see what it is? I'd like to know for sure. Anyway, I tried that 1K resistor, and the charger did go blue and start pulling about 700W, but AFTER THE BATTERY CHARGED IT WENT BACK TO GREEN. Are you seeing this? Anywhos, I'm looking at options for my waste of $200 on the WF-8955-AD. I may pull the charger and move it where the battery is to see if it actually works. I may disconnect the WFCO charger completely and buy a separate charger (Progressive Dynamics or whatever) and put that next to the battery. It would have been nice if WFCO and the RV manufacturers actually got together on this and worked it all out, but it looks like WFCO only benched tested their stuff and the RV'ers just slapped it in without regard to wire gauge. "8 gauge supports 55 amps, so what's your problem!!?!?!? Whaddya mean voltage drop!?!?!?!" Sheesh. Oh, I have contacted WFCO support just recently, and I got the same questions you did. I have since been told that the voltage drop is preventing the WFCO from functioning properly, that has ramifications for charging and the battery, and that's that. They didn't offer a jumper. I have read that Lithiums do need to be charged properly to 100% periodically. I have a Victron solar charger that does work and will do Bulk and Absorption modes, so at least that tops off the battery. I have a NOCO Genius 10 that will also do the Lithium charging when I have the battery in storage over the winter. But IMO the WFCO and the camper people really need to step up. Thank you for sharing your experience with this.

You didn't buy me a new camper!

Seriously informative. Thank you. Straight and to the point.

Its the firmware!!! Dude, just contact WFCO and give them your address and ask for the "jumper" for the 6 pin location in the MBA. Stick the white jumper on that 6 pin, and it will charge at lithium ONLY. That's what I did for my WFCO 8955 MBA - AD unit. Then make sure to put a notification sticker somewhere on the unit for the next owner that its set to LITHIUM ONLY.

Thanks for the video I just got a lithium battery, and I have the same converter, I was thinking of getting the new one but I’m unsure with all the problems I’m seeing.

I have a WFCO WF-8735-P That was broken right now so I was trying get that parts but not avaliable should the WFCO WF-8735-AD works as my replecement but I only have lead acid.

I have a few of the old red model 2. 400 & 1, 750 and one black 750. I do think the new black model is better somehow. My red ones never had the fan on all the time, however one red 400 did turn the fan on much sooner than the others with the same load. Either way, I think the newer black one is better... imo. Thank you for making the video. 👍

Good video! Looking at the 5000 predator

Also one cat i read was going to do a class action law suit , but haven’t heard anything since !!! Good luck ! Like i said get a progressive dynamic

I was an RV tech for a long time back in the 90S- 2004 as far as your wfco power center i have the same problem wfco tech support tells me ya gotta run your battery to 2% which to me is F-in stupid , i said it doesn’t say that on the box or instructions! They basically told me tuff shit ! Im going with a progressive dynamics switchable power center , see if that works , all the stuff your doing you shouldn’t have to wfco just SUCKS !!!

😊 I wish I was doing what you're doing right now 👍

I installed the same power center from WFCO.....Have the same issue, what an unreliable POS, ended up just buys a lifepo4 charger......that AD is a joke.

I have the same converter software version 1.19 in a 2023Forest river Flagstaff E pro 20 BHS same issue lots of tips and tricks out there to trick it to work but no guarantees it seems that WFCO and the RV manufacturers do not communicate with one another obviously the manufactures need to understand how the product works that they’re installing unless they just don’t care and the solution that WFCO has come up with is ridiculous it’s unfortunate But from what I have seen online lot’s of people just outright replace the damn thing which may be what I’ll have to do too bad forWFCO instead of admitting to their mistakes and correct in it thereby creating more loyal customers and more revenue Of course I’m sure the majority their sales are to the RV manufactures and as long as they’re buying them They’re making money know if the RV manufacturers started complaining I’m sure they would’ve changed the design immediately ( Put the switch back !!! ) anyhow enough of my rant this would seem to be the more solid fix by replacing it with this unit Progressive Dynamics PD4135KW2BV I believe this is the correct one for the WFCO 8735 AD

Does it require to hooked up to a battery at all times? Im trying to find something small to take camping so i can hook up my projector & watch movies in the woods & im going camping next week

I've had mine a couple of years and use it for my RV pull trailer. It is great except that the co sensor shuts it off. I just tried to bypass it. I have yet to test it. Thanks.

Question for you. I want to be able to keep a steady state of charge on my portable generator stored in my non powered shed for ready emergency power outages and have some occasional lights in a rare occasion when I go to my shed at night..Would the battery controller that comes with the Harbor Freight Thunder Max 100 watt solar kit be able to keep my gens 12V 18 Ah lead acid battery topped off like a trickle charger would?

how is the “clear view” feature? is it comparable at all to live scope ?

😅

What happened to step by step, most ppl have little or no knowledge of how cars work!! Not enough Details

Those panels barely put out half of their rated amps. A single 100 watt panel will be a huge upgrade. I did the same some 10 years ago. Greetings from Jamaica.

Mine no longer works after using it three times. Error light comes on. Bought the newer model and took the other one back. Junk

Hello! What kind of batteries did you get? I'm currently researching this and I think there's three different kinds? If you're open to it, I'd love your advice on my situation when I get my rv next week. I really think I need to upgrade the batteries!

What size wire did you run to the battery

Gen x = no love

Buy yourself extra cables if you use it allot you might run into a jam and need them one day. I had to buy extra set cause i burned the first set up the battery has worked great iv had mine for 2-3 years and its still working strong

Never disconnect the battery before first disconnecting the panels or you will blow the charge controller. What prob saved you so far is that the panels dont produce much power. Nice startup project. Greetings from Jamaica.

Exact same thing happened to mine

the red one does not have an in line fuse.

How much did you pay for the jupiter? Good video

I've never been dumb enough to burn myself. 😊

thats an old trick young buck

I do that all the time

DUDE Almost burnt myself twice the other day doing just that, this is ingenious. Thanks!

To long im out

Awesome lights!!! Great for truck lights. I bought one for $7 (not those) from TSC and it's my truck light. Couldn't be more pleased about it.

Fucking genius! 🙏 Thank you. I will most definitely be using this in the future!

That's neat

Is our first winter living in Rv. THANKS A LOT MAN!

You really should go ahead and remove it so you can clean and relube the guide pins👍

Never do this. This is why you should have a professional do uour brakes...... or just act like a professional. Let me know how you pull the bottom pin to clean and lube it before reinstalling it.

What kibd of caliper is that? Mine is completely solid

You need to take the bottom bold out and flip it up instead of down so theres no unessary tention on the brake line

Try this on a rotating piston caliper. It wont work.

Knew that shit in the 90s

Ive been doing that since i started working on cars with my dad in the garage

My granddaddy taught me that when I was 12

Just make sure ya dont screw the line up lmao

N fuk da rotors right who needs a resurface lmao

Also depress the piston all the way in before you pull off the caliper. I never use caliper depressing tools.
