"Action" High Performance 800lm 1200mAh

Hi, did anyone of you get such a light?

I got one yesterday just because I was curious what exact battery is in it.
Suddenly I was unable to open up the light as there is no obvious screwing mechanism.

Only thing I could unscrew was the pill…
The pill is connected to a PCB (with 2 wires) which I couldn’t get out.

Maybe anyone has experience with opening “1 piece” flashlights?
Or are they really made out of one piece (how)?

Thanks
