Description
The WHY2025 badge had holders for unprotected 18650 cells. I'd rather have protected cells in mine, so I made this adapter to make a protected 18500 battery fit in the holder.
Use at your own risk.
Each adapter requires either a flat-ended M6 x 10mm grub screw, or a cut-down piece of M6 threaded rod.
I have attached a mitre box for cutting M6 threaded rod.
