Thanks, sir... I noted on their website they had a version designed to charge down to -4... I couldn't find anything on the site that spoke to how this was accomplished, but assume there's some sort of a built in warmer for the battery... these are a bit more pricey, but certainly cover the risk of finding oneself in below freezing weather, eh?
It is accomplished by the nature of the chemistry and a passive battery management system, which disconnects -4 f, in Battleborn jars.
The one exception I know of is lithium titanate cells which can be used and charged down to -40.
I really would not mix amp-hour capacities unless you "get it in writing" from the battery maker.
