New to the forum as we just pulled the trigger on a Beyond 22D-good price on a 2026 because the new 2027 van are coming out. I wanted the 2026 because the new 27 don’t have a spare tire and the other changes seem minor for the price difference. We of course found the coach we liked (color and options)half way across the country but we are excited for the trip to pick it up.
I didn’t want the lithium model because they have eliminated the Cummins quiet generator for an additional alternator which seems like it could be a drag on mpg especially with large amp hours to recharge and I suspect trouble after a few years of heavy use, verses a 2.8 Cummins. So ours will have a 470 amp hour lithium battery replacing the stock Group 8D AGM battery (same size but lighter and maybe 3X the amp hours) and the quiet Cummins.
I am in the planning stage right now (ordering the battery, remote terminals etc). The dealer where I am purchasing the Beyond doesn’t seem too familiar with making the swap. I have watched a You Tube video on how easy it is to do (except for physically handling the 8D battery) but I can’t find anything on how to setup the Van’s system on recognizing lithium vs AGM. Has anyone made this lithium conversion on a 2025 or 2026 (with the Garmin) and could share the process to setup the new battery type?
Thanks, look forward to sharing our experiences and learning from The Coachman Owners Club.
