Anyone cracked open a BlendJet to see what's inside?

Curious if anyone here has actualy torn down a BlendJet. These are cheap enough that people just toss them when the battery die or the motor quits, so it’s curious as to how serviceable these device are.
They are largely glued or ultrasonically welded together; there are no screw on the base, the newer models have a USB-C charging port, and the motor and battery is under the device. The blade is likely pressed onto the motor shaft rather than having it thread onto it.
The battery is likely not replaceable; rather, are the cell spot welded to a board that is difficult to access for replacement? Is it a brushed DC motor for instance?

yeah I cracked one open last summer when my gf's died. Spot welded shell. Used a thin putty knife and heat gun to pop the seam. Inside the battery are two 18650 cells spot welded to a BMS board. Not impossible to replace the battery; spot welder and soldering skill needed for the cells.
