Best Winter Storage Practices for 2022 Micro Minnie 2108TB FLX in Extreme Cold

[parshal]

Hi everyone — new member here. I’ve searched through the forum but haven’t been able to find a clear answer on this.

We’re purchasing a used 2022 2108TB FLX and will be storing it in a pole barn with electricity available. I read recommendations about removing the batteries to a climate-controlled space during winter, different approaches for <30 day vs. >30 day storage (100% vs. 50% charge), turning the battery off, etc., and I’m trying to sort out what makes the most sense.

We do get occasional cold snaps down to around -20°F, but they’re usually short-lived. It’s not uncommon, though, to have highs in the single digits for a week at a time. I’d really prefer not to remove the battery every time we get a cold stretch, especially since we may want to use the camper mid-winter.

My current thought is to just leave it plugged into a dedicated 30-amp circuit. However, that would keep the battery at 100% continuously, which doesn’t seem ideal long term.

What are most of you doing for winter storage in similar conditions?

I live in central Florida, where temps can be below freezing for 6-8 hours occasionally for a 2-3 week period. I leave my RV plugged into a 50 amp circuit, with a dual 30 amp breaker at the home panel. It was wired that way, when I bought the home. It has 10 GA wire, so I haven't bothered rewiring it for a true 50 amps. It has no ill effect on battery life. I can run air or heat in the RV and have NEVER tripped the home panel breaker.
EDIT: I missed that minus twenty degrees. My experience is completely irrelivant.

Yeah, the minus 20 is a kicker. But you did answer the real question of negative effects on the battery from constant shore power.

Thank you!
