As it's chuffing freezing, would there be any benefit to putting my battery inside one of these to retain a little heat?

What size is your battery? Mine would not fit in that bag.

Have a few different ones to go at, all bottom tube mounts, nothing bigger than a bottle battery, that picture was just an example of the kind of thing I meant.
