Battery bars completion

I've been fighting with the cold all day, trying to shoot in my unheated garage on the coldest day since March (temperature sat around 6 degrees all day). Cold hands are my excuse for blowing a bulb on one of my arri lights (they are 150 w and not big enough to warm up my garage). Erik was over a couple of times and we completed some of the most complex shots together (without anyone losing an eye!). At 10:30 my battery died and I've decided to resume in the morning (two sequence remain and one of them is set up and ready to go).
