@ Xeno - I had a a faulty generator once and I got 20 miles out of the battery only.....can you share some more info on your setup?

Maybe the genny was draining the battery at the same time, or the lights were on or some other electrical drain?

It should run for quite a while :D

If in doubt strap a leisure battery to the rear seat.. not sure it'll save you any weight but it'll last a while

CMSMJ1 - Sorry mate but don't know the weight of that its probably not that much lighter
