*LOOK* Boosted Board Standard Range Battery SR Fits Stealth Plus Mini X Mini S V3 V2. This is the slimmer pack, not the extended range pack that comes on the Stealth and mini x. Feel free to send me a pic of your battery/board to confirm compatibility. This is a stock replacement for a mini S and V3, or anyone looking to use a light weight pack on a V3 or Stealth. This is a brand new replacement pulled from an unused Mini S.
