Our old trailer (2007 Komfort) had a WFCO 8955 converter in it, I could NOT ever get it to go into bulk mode, not even when I moved it within a few feet of the batteries, tried everything. I did a thread on it. (I ended up putting a PD9280 in a new location closer to the batteries.) Any converter thread got pretty heated back then as I'm sure some of you will remember! ![[emoticon]](http://www.rv.net/sharedcontent/cfb/images/wink.gif "wink")
We just bought a 2019 ORV Timber Ridge which unfortunately also came with an WFCO, this time a 8955 Lis. This is the one with a lead/lithium switch.
This trailer came with 3 - 100Ah LIthiums, has 600 watts of solar panels uptop and has a 12v Norcold fridge. (I might add another 200 watt panel and additional 100Ah Lithium if I need to?)
So are these new WFCO still as bad as the old ones?
If they're better I could replace the charger with a 8975 if it fits? (I'd have to upgrade the cables to the batteries I know)
Either way I'll be wanting to upgrade the charger for one as big as possible that will run from my Honda 2000 genny.
I'm hoping to shorten the learning curve re. lithium charging, this is all new to me.
Thx
Will

Interested to hear once you test it out.
I can confirm in 2017 models, WFcOs are still junk.

Without a battery shunt like Renogy or Victron you'll never know what your charge rate is. Or the real state of charge of the batteries. Unless maybe your batteries are bluetooth themselves. I have a 2018 ORV Creekside with the old non lithium 8955. With a Renogy shunt I only get about 5 amps max charging current into two 12 volt flooded batteries. Drooling over all the Victron stuff and lithium batteries currently. I do have one 180 watt solar panel that came on the trailer (Zamp). It has capacity for two more.

I do have a shunt with a display, looks similar to the Victron one.

If your charging amps are above 40 amps I'd say that's ok. Most lithium batteries have BMS's that are 50 amp or 100 amp charge/discharge capable. 55 watts is the max system output including lights, accessories etc. Whatever is left is for charging. If you're not having issues I wouldn't change it yet. You want charge voltage around 14.4 for lithium. If it's 13.6 or so that is for flooded lead acid. Lithium batteries don't have float mode. There are several good youtube videos show lithium charge and discharge curves. Do you have the Zamp 30 amp solar controller above the bed like mine? Make sure it is set to lithium also.

I have a "crappy" WFCO 68100. It's 11 years old. I have no idea if it goes into bulk mode.
Is that bad?

IMHO,
WFCO "Made in China", Progressive Dynamics "Proudly manufactured in the U.S.A"
I have removed several brand new WFCO converters and replaced them with a PD. Problem solved.

Amazon shows it being a 100 amp three stage converter. The only way to know if it's reaching bulk or float mode is with a battery monitor that measures amps as well as voltage. My wall mount battery gauge on my trailer will show dead when dead, but as soon as start to charge batteries they show full because it's just a volt gauge. I don't think what you have is junk, but I do prefer Progressive Dynamics. That's what I've used in two converter changes and plan on putting in my new to me travel trailer. The charge wizard pendant shows what mode your in and you can force it into any mode.

They're both foreign to me.
