E-Maxx cells

4000mah+ should easily get you 15 minutes- the guys on the traxxas forums rave about both brands, and 30 minutes is about normal with titans or hvmaxx systems, so MMM might be a bit shorter; I think you'll have to find out the exact runtime you'll get the hard way.

The 110volt charger wont work from ~220volts, you'll have to locate a version sold in europe or the UK for our different mains voltage- the travel adaptor just changes the type of pins on the plug.

You could power it from the lighter socket if you switched the leads, that wouldnt be a problem.
