sorry that that lipo puffed.

when it's cold outside, I take a plastic thermo bag (eg. for beer, sandwich), and some of those warming-pads. I put the lipos into the bag.

when I arrive at the spot (about 20 mins by car), all lipos are nicley warm, round about 30 deg. c. and the beer's warm, too...

very cold lipos have a high IR, that could possibly damage the esc, or even the lipo. and, you have not that much punch.

that bag worked well so far.
