Before buying more xtar 2600 batteries for relatives I just couldn't resist to look what's inside
Hmm, no kapton tape for aditional insulation, metal strip little too long, nice thick rubber spacer betwen cell and protection circuit.
Protection circuit has two mosfets (with place for one more) and single protection IC, looks pretty standard.
Overall it seems OK but there are potential weak spots, little bit of kapton tape under (and/or) over metal strip would be nice.

Nice pictures - thank you .
Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….
