A small detachable shelf could be built (with wheels and an edge) that goes in above the battery, maybe next weekend. Need to find some round bar that fits into the square tube I'm using, very similar to what I did for the big trolley (jerry cans/tyres).
Was thinking about doing a basket that fits into the bottom of the trolley, but need to be careful about the balance, do not want heavy items in the basket. Also more than likely will put an edge on the top so that nothing rolls off.
