A few weeks ago when we had days at a time of sub-zero temperatures the El wasn't fun to drive. Pre 2006 cells suffer really badly in the cold and just won't give much power off. They like to be above 10 Degrees or so before they really start to work nicely.
Luckily I found one of those sub-soil heaters that you can pick up at a garden centre for £30 or so. Fitted and placed in my battery pack I can now report the temperature this evening at about 6pm - with the windchill well below Zero to be about 18 degrees C in the battery pack! Bonza!

Yay for simple solutions!
