Thanks guys. Since the battery life seems to be a worry for many and lots of people seem to have 4 -5 batteries I thought a more elegant solution may have evolved (other areas requiring charging stations for multiple batteries have evolved that way I've bought them for tools at work and radios, I'll grab one of the suggested ones, combined with the 2 original chargers i would be covered for an overnight charge on 80% of my batteries during a busy period (it's not been a huge issue yet)
