Hi,This is my first post. Just brought home my 2022 260RD . Wasn’t able to get the answer to a few questions at dealer orientation. I would like to convert to a Lithium battery 200amp. My converter is WFCO WF-9800LiS series, manual says it it’s charging profile can be changed from lead acid to lithium’s. You install a jumper wire in the back where connections points are, and that changes it to a higher voltage to charge lithium’s. Has anyone with a WF-9800LiS changed it to lithium charge profile? Where is my converter located?, and how do I access it.

Sometimes the Converter is behind a panel next to (or beneath) your electrical service panel.
It looks like your 9800LIS is a stand-alone unit, these are usually located behind the Electric Service panel. Often you will need to remove a panel inside the hold area to gain access to the area behind the electrical service panel.
This is the first time I have heard that the OEM/WFICO Converters can be jumppered (or switched) to allow them to charge Lithium batteries. This is good news for the RV Industry as a whole.David and Peggy

Thanks to all who replied here. I've been busy wiring the battery bank, but wanted to let you know that I got the lugs I needed from a welding supply shop here. Holes were bigger than I wanted, but I made up the difference with washers to ensure adequate contact and secure fitting. I was also able to source some from amazon after the help here, and I've got to say the ones from the local welding supply were MUCH higher quality. For the crimping I used a hammer crimper, and it worked well enough. Not pretty, but effective.

Hi there. I'm confused. 4/0 wire is good for 315 amps at 90 degrees C. That's the size wire used for 400 amp electrical welder cables. You'll need to either solder the wire (with a really, really big and hot soldering iron), get the expensive lugs that can be smashed with a big hammer, or a use a hydraulic "studder" to make the correct crimp for that current.
#4 copper wire is good for 100 amps. I connected my two batteries in parallel with #4 wire.
To finally answer your main question, you should look up and go to a local electrical supply house where commercial electricians go for supplies. FYI, those lugs are several dollars each, and it is doubtful they will have the ability to crimp them for you.
I am sorry if I sounded condescending as that was not my intention. Just trying to help.

When you have a 3000 Watt Inverter and you have a 12v battery bank, the amps can get rather high. The other reason for running such high gauge cables is to minimize losses in your cable runs. Most 12v systems use 4/0 cabling for the 12 volt cables going to the buss-bar, the Inverter and between the batteries.
Such heavy gauge cabling is not required if you are not running a 3000 Watt Inverter, or are running your system at higher voltage, for example: I am only running 1/0 gauge cabling for my 24 volt system with a 3000 Watt Inverter.David and Peggy
