Yeah I noticed it works on my newer batteries, like the LCD ones and the Cherry Jazz battery I won, but it does not work on my First Run Go Go batteries from back in March. I think that may have to do with some of the improvements they made in the new production models on the battery connector.
I am just glad you like itThe 510 stuff really does hit really good on the higher voltage Go Go batteries

I have been trying to catch the GoGo to 510 adapter when in stock. The GoGos I have I got back in May. Are you saying that the adapters will not work with bats this old? Thanks...
