Even back in the old days, when we were toting 12v batts to the track (and Novak sold gel cells), someone always brought a portable generator that everyone could run an extension cord to so as to power their equipment. Even at large races, with hundreds of racers and many pitting out of trailers, the sound of portable generators is commonplace.
Like I said, haven't seen a 12v battery brought to the track in years and years.

I had no idea you Brits had it so rough. My apologies.
But please don't take me to task when I did offer a full explanation of "do's and dont's" to answer the OPs question in full.

take me to task???
