Hey guys. If you are like me that dont want to use the 18650 mode because you are afraid to screw the telescope to hard to avoid the wobling tube.. I found a very simple solution for eliminating the wobling... JUST TAKE OUT THE CAP SPRING i have a no brand battery that make perfect contact on the negative and other battery that dont make contact i just cut the top part of a spring and put in there. Perect you can now screw the telescope until stop and get a solid feel now with no pressure / tension of that really hard spring pushing the battery very hard against the pcb.
