Ok, Its been way too cold, windy and overcast to do much flying. Winter is here and my battery is self discharging and you know how hard our airplanes are to start.
I bought one of these on sale for $9.95-

I cut off the clips and added a cigar lighter plug from Radio Shack. Less than $15 total cost.
Plugged into the cigar lighter outlet that came on my Carbon Cub it keeps the battery up if I don't fly.
A warm engine, a hot battery and a sunny day are all you can ask in the winter!
