I've got the problem where the screen comes on when I press the button but then shuts down again, when I have batteries in the mod and connect it to the PC it does stay on but then all the values on the screen are 0.00.
in device monitor cell 1 says 0.01v but cell 2 says 5.28. seems like a battery balancing issues on the boards end as the batteries do work in other mods without any issues. The mod is a little older but I has worked fine up until 3 hours ago.
