You can use them in the mini. I am not sure if they will work with the spinner I will give one a try a bit later and let you know@Stoodlepuff I see you have 0.8 ohm coils for the MPT3. Can these be used with a Spinner? Or do you need serious batteries to use those?
Edit: oh wait, the bottom says ProTank 3, so u guess not the Mini.
