for my next project, I would need to use a LIPO battery as input power.
As you probably know, LIPO batteries are sold with a JST PH male connector. Something like the picture here:
they are very common in ESP32 projects. I cannot find the female connector (which should be soldered in the PCB) in JLCPCB. Do you have experience with this?
Maybe a different solution if the connectors are not available?
