They are supplied with the TFV8 Baby V2 tank on its own - but because the Mag Grip and Stick V9 are lower power than the best for them they only recommend the S1 and S2 for them

I was thinking/hoping with the bigger battery that would accommodate the high-power coil. Basically that the S1/S2 are best with a 18650 battery.
