As mentioned previously, I determined there was no easy way to fit my SOK 206Ah Lithium battery in the battery box. It would technically fit in the battery box, but would need the battery tray removed, which would be no small task after speaking with OEV. Things are bonded with robust sealants. Very well built! But even though it would fit within the battery box, there is not enough clearance to get it there. Backup plan was to use a lithium battery that was the same footprint (particularly the width) as the stock AGM battery which would allow for the install. My Battleborne 100Ah arrived and I'd had time to test it so was ready to install. The OHMMU is another lithium option with the same width as the stock battery and it is 150Ah. Both are good options and there are some others, too. Using the Battleborne or OHMMU also allows the OEV battery tray and top plate to be used which are both very strong and great looking.
First step was fill the two unneeded vents with expanding foam. These vents are not needed for AGM or Lithium batteries. Future OEV campers will not have vents and will instead have warning stickers that only sealed, non-vented batteries can be used. I used the "Fireblock" version of Great Stuff insulating foam sealant, hence the orange color. Great foam is rated as R-3.7. I filled the two vents from the inside, let it dry and expand for 24 hours, then trimmed.
Battery slid right into place and OEV battery tray and top hold down plate fit perfect. I reprogrammed the REDARC for Lithium and good to go.
I wanted to exercise the battery to test it, my install, the REDARC, etc. And, it's good for lithiums to do one or two fairly large discharge and charge cycles to break them in. So I let the REDARC charge it 100% and calculate the SOC, then turned on the lights, fans, fridge and connected some loads to the 12v ports and drew it down from 100% SOC to 13% SOC which took about 8 hours with everything I could throw at it (I don't have an inverter so was limited in the load I could pull). I then plugged in the REDARC and let it run back up to 100%. I typically have the REDARC max charge set to 5A or 10A, but turned it up to the max 30A and "let 'er flow"! Ran it up to 100% SOC and left REDARC plugged in for 48 hours, then unplugged and ran the battery back down to 60% SOC and left it sitting there (since lithium are best stored at 30 - 70% SOC. Happy with the setup and will be putting the camper back on the truck and de-winterizing this week.
