Edit: I do see that the JST is wired backwards. It's not difficult to fix. You can just pull the pins out of the plastic and swap them.
OH, where did you get the JST wire/connector? I have seen ones that are wired backward. I can't be sure from your photos, but I think that may be the problem. Please see the info/photos here.

I bought a dozen or so including sockets from some seller on eBay. They're all wired that way. I have reversed the contacts in the connectors now and will proceed from here.
Why would the batteries appear to charge when the wires are backwards though? I left them plugged in with the leads the wrong way and after a few hours the green LED on the back came on indicating that they were full. When I reversed the leads and tried to boot I got the red "Low battery" led on the front immediately. What is the green LED on the back actually indicating if it's not full charge?
