After my leisure battery packed up late last summer, I went for one of these:

Will do a full days charging and more, can charge around 9 or 10 2S LiPo race packs without any problems. When I get home, I just stick it on charge with my Orion Adantage Touch and charge it back up. I've also run soldering irons on it, all through the winter in some of the coldest conditions I've raced in. Plenty of power for a full days racing, and probably enough to get through the next day aswell!
So much lighter, cleaner and smaller than any other option! And Corally type connectors fit perfectly into the screw holes in the top!
