18650 to doubel Mono Cell

Hello,

Here my solution of a 18650 Cell to a doubel Mono Cell.

After i reciving an old Flashlight as a Present and the Mono Cell run out of energy i came up with this Adapter.

For the 18650 Cell Holder i have take my favorit battery Holder the:
"Flexing battery holders with integrated spring"
Thank you enif.

I have put a extra slot for a "TP4056-Protect" board.

Caution! The original light bulb from the Flashlight is to weak.
My light bulb is RIP after the photo. :-(

If you have a problem or an improvement for this thing please let me now it.
Sometimes i am professionally blinkered :-)
