Mini Pro v3 JST connector not working

[Jatinder Mann]

Can’t use my LiPo battery with Mini Ultra, I have 2 boards one works with the LiPo the other doesn’t. Which makes me think I may have a faulty JST connector or something along those lines.

Does anyone else have this issue? If so what did you do to fix it?

Thanks,

Hi Jatinder,
Can you check if the JST connector pins on the board is properly soldered and has no cold solder joints. I do test every board with a Li-Ion battery during production but it’s possible in one piece of these many batches there could be a cold solder joint. If you can take a close up picture for to check it would be great. You can also take a meter to check for continuity from those 2 pins on the JST to those VBAT & GND pins on the header.
