Lead Acid to Lithium Upgrade

See if you can run the LM2 data stream and get the same information. I think they did not change the data stream except in the ultimates.

Worth a shot though.

A caution on installing a Lifepo4 capable converter in the original location. I did this and despite the converter manufacturer data that 6 ga wire was acceptable between converter and batteries, my Victron shunt was telling me that charge rate was restricted to about 20A with the 10 ft run of OE 6 ga. I moved the new converter to within a foot of the batteries and wired with 4 ga. Charge rate is now at 55A which is the capacity of the converter.

Another plus of putting the converter in the front compartment of the 5th wheel rather than behind the aft wall of the pass through is that the cycling cooling fan is no longer audible inside the trailer.

I'm wondering if there is more to this? 6ga free air rating is 80 amps. Most RV DC battery wiring is fairly close to a free air style of installation 60amps in a cable. I'm not doubting what you saw, but wondering if the 6ga run was really the culprit. Maybe connections? I have 3.3mm wire from converter to battery and saw 40a when the battery was around 60%....but the converter was running other stuff in the trailer as well. So I was resonably happy with that.
FYI 3.3mm wire is in between #6 and #8. Wonder if GD uses metric wire on units for Canada?!? First time I ever saw metric wire designation in wire smaller than the MCM cables.

Agreed that the OE 6 ga wire should have worked better. Even the converter manufacturer specs indicate this. The original wiring from converter to batteries disappears down into the underbelly and may have high resistance connections down there somewhere. Rather than open up the coroplast and dig through that maze, I moved the new converter closer to the batteries . . . as much to get the cycling cooling fan to where we couldn't hear it as to shorten the recharge time.

For sure. Closer to the battery or batteries is definitely a plus regardless...and I agree with the cooling fan. The PowerMax we have now is a bit louder than the WFCO we removed.
By the way, did you just wood screw the converter to the front compartment back wall?
