I am somewhat dissapointed that the low cost lithium battery suppliers, SOK, Amperetime and CHNS, don't include a sensor to stop charging when the temp gets below freezing. It could only add a few pennies to the cost.
But I don't see it as a deal breaker. When I winterize my coach for the season I just disconnect the negative cable to the batteries and they can't be charged until I reconnect next spring. Not that big of a deal.
I don't use lithium batteries, yet. So far the 200 amp hour, 100 amp hour usable capacity of the $380 I paid for a pair AGMs are doing fine for as much as four nights of dry camping. If I needed much more I would do all of the things (well maybe not the BIM changeout until I could confirm it was required) noted above.
