Hi Todd,
My experiences with battery blankets have not been good. Each and every time, battery life was reduced. How ever, that information is from the 1990's. Things may have changed.
Of course if the bank is LI based heaters are needed. I just found out the GM Bolt has heaters for its battery pack.

Thanks Don, We just bought a bunch of battery warmers ,for the batteries in our fiver. When looking at them, I thought they might be great on a propane bottle... but I like the idea of the magnetic block heater. I see one in our future! ?? ??. Thanks again
