Battery Heaters, cheap

I have no economic interest in this of any kind.

I just ordered a bunch of these 24v 150 watt heating pads for use with my EG4 batteries. At $6.99 each in bulk, they are a steal. Doesn't get too cold here, but it does get down into the 30's F and I want a way to keep my batteries warmer than that. Needs a thermostat etc., but otherwise looks very useful...

 
Just a quick update - take some care if using these with a "48 volt" battery system. I put two in series and applied power from my battery pack (which outputs something around 56 volts when fully charged) and the magic smoke came out of the heating pad... I then put three in series and that worked fine.
