You need:

-   1 x 18650 Li-Ion battery
-   1 x metal saw or dremel metal cutting
-   1 x soldering iron…
-   Heat Shrink Tube? cheap but really efficient

Open the WowStick and remove the motor/button block. Easy, you can follow this:

Cut the tube like the picture and fold the end to fit a 18650 and some space for the spring (took from the original cap)

Put back the motor/button block with the negative solder properly.

Put some tin to bring out the positive pole.

That’s it. You have a high torque / high speed / long life 20$ electric screwdriver.
