Turning off the Charging Process
After accepting the Limitation that I can't - and shouldn't attempt - charging my new BB Lithium batteries, it occurred to me that a few of the places I might like to go could get to freezing, or belo...

Exactly right. You don't need to do anything. If the batteries think they are too cold to charge, they won't charge. It is controlled by the internal BMS.
Also realize it needs to be below 24F for a significant amount of time for the batteries to activate their low temperature charge protection, they have a lot of thermal mass.

Battle Born batteries have a built in BMS (Battery Management System) that prevents charging at temps below freezing. No need to disconnect battery. You can still discharge well below freezing.
X2. The whole purpose of the BMS is to keep things from happening to the battery that shouldn’t. A BMS isn’t required to charge a lithium battery. It’s what is needed to make an acceptable lithium battery for use by non-technical consumers.
