Does anyone use a battery heater on their RV? We're probably headed out of town on one of the very cold upcoming days (<20F, unheated hangar), and i was considering adding a battery heater (remotely controlled) to warm the battery before departure.
I have a 25W silicone heating pad, and I figure I could glue it to a piece of aluminum and wrap that halfway around the battery. Making a few assumptions, that would give me about a 2C rise in battery temperature an hour if there were no heat losses, which there certainly would be. So if I turned it on 10 hours before departure, I figure I might get a 10-20F increase in battery temperature, which is enough to make a difference.
Thoughts?
