Wait you can’t leave your lithiums in your boat go to freeze ? Say it dips into the teens ? I understand you can’t charge them under 20 degrees but storage you gotta yank em every time ? That’s incredibly annoying if you want to fish any warm spells on the river . Last year was great for that.
No, I don’t think so. Most manufacturers say storage down to -4 in their specs and, personally, I think that is more a result of that being the tested value more than the “real” value as concrete info on the harm of being stored in lower temps is pretty hard to find.
Also it’s that you can’t charge them below 32. I think the better minimum to charge at is around 41 and that’s what self heating ones heat themselves too before allowing charging.
edit: Litime specifically says 14 for minimum storage. -4 is what I saw many other manufactures say when I was looking for mine. Trojan is the only one I’ve seen that says -40
