I can 3D print a frame which will hold the board and the battery in desired position. I made a simple frame for FCDEV3B to hold it in place on the bench while PCB is not touching anything on the surface.
We can also have a surrogate connector ripped off a real battery and a small frame folding it connected to the spring pins on PCB. I have C155 and C123 to experiment with if anybody is interested.
