Glad it was useful, as you can tell it's grown on e as a solution.
The battery I have has a small DC barrel socket for direct charging but I've never bothered investigating as I've never been in a situation where I would want to charge the battery outside of the fridge.
Even if I had 2 for a longer run I could still charge them up beforehand in the fridge before I went.
