ode what version did they start being compatible moving forward? Bio cell?
Yep. The 2nd gen MyFly adapter. I can't remember the exact numbers, but the Amp Cell and Bio Cell were different. The Amp Cell MyFly was a 1 shot deal, none before or after were compatible with it. I think it was the MyFly6. Before was the AFT and after was the MyFly8, if I remember right.
