Personally, I've yet to see
anybody do that - but the tracks I've visited, all had plenty of AC outlets, so there never was any need to go that route (since everybody needs either an AC/DC charger or a PSU for his DC charger at least for back at home, anyways - and bringing that isn't any more hassle than lugging an extra big battery around - plus you're not limited in your charging at all).
So, yes, it's easily doable, but once a track has sufficient and easy AC access, I'd never even consider going that route. But YMMV.
