Those are 2.5 mini's then because they also said the extension only allows the 18490/18500 battery.. if they were the full size 2.5's then the extension would take it to 18650 batteries..
It seems they know not what they sell!
I knew not the specs of a classic, so it's good you knew!
I looked at those, and the description said it had the P3/510 connection.
who knows what they have ... could even be a PloVari
