@stuart,
At JLCPCB there is a maximum limit of 30 BMS for soldered the parts.
I asked them how to do, as the setup costs and the parts swapping costs are relatively high.
They told me to use “mousebites”
Google told me that they are brackets between prints.
Example picture:
Like many users here, I don’t have experience with PCB, except upload Gerber files to PCB maker 
Is it possible to create new Gerber, BOM and pick’n place File that have 4 BMS ?
I have 2* 16S battery.
Sadly now I’m missing 2 BMS for the other array.
During my order the attiny and R19, the 0605 thermistor wasn’t available at JLCPCB.
I ordered and have all the parts.
Now waiting for the microscope to be able to solder the thermistor.
That’s really tiny
For other people who have the same issues, having a set of 4 (or 4, 8 and 16) would be really helpful.
I don’t know if it is possible to use the Gerber and other files to make mousebites in a PCB design program.
If that is possible, please tell me what program is most dummy proof to do this.
Thank you!
Help?
Apparently I can’t reply to this question as I have a maximum of 3 posts for this forum ??
(This number of 3 posts I already exceeded a month ago)
