Hi, I recently flew around our local hydro electric dam (
) but the temperature was barely above freezing, it was about 2c.
To ensure my batteries weren't too cold for flight I cooked up some porridge, double bagged it in sealable freezer bags, then put it in a chilly bin under a couple of tea-towels. I then placed my batteries on that and covered them with another tea towel. When I went to use them on site the P 4 reported back that the battery temp was 20c (70f). Perfect.
One other tip is to let the porridge sit in the bin for a few minutes to warm up the inside, then before I put the batteries in I wiped off the resulting condensation from the inside walls.
After the I'd returned home I went to the local duck pond and fed them the porridge...the loved it! I could have eaten it myself, but I think the ducks appreciated it more.
Anyway, the batteries were nice and warm, it was only my fingers that were cold!
