This corresponds with the Powersonic chart, so at -10C (15F), you have
a 30% loss of capacity. For winter flying, and spring or fall flying
in places where you can climb to, say, 10,000' agl, it's an important
factor. Especially so, when you know your encoder will likely be using
it's heater, adding 50-150 milliamps to your current drain.

Put a insulated cover around the battery, and the heat of discharge will
keep it warm and the capacity up, unless it is seriously freakin' cold.

Insulating it will keep if from cooling off as quickly, but I'm
skeptical about the amount of self-heating. Do you know how much it is,
or where I can find a reference to it that applies to the batteries we
us? Insulating my battery is difficult due to it's location, so I'd like
to know it's worth the effort before attempting it.
