Yep the Speedy Models one looks similar to mine but doesnt really say what it does. It did mention it'll do 6 & 7 cell batteries so thats fine for what you want (7.2v & 8.4v). Unfortunately i cant access ebay from my work PC (dont tell the boss im here

) - I'll check later from home to make sure about the other one Matt.
They usually have a peak flow auto cut off so you dont have to bother with working out charging times and all that when fast charging, just plug in and hit the button, shouldnt matter if it isnt fully discharged. And they're usually Nicad or Nimh compatable.
