no problem, did you see my part about using 2 of these modules per cell to see if it would run 2a discharge if used in parallel?
also seem to be having a problem with the module controller reverting back to 4100mv and 70c, i change it to 4000 and 75c click save and then a few hours later its gone back to 70c and 4100mv
My first post, though Iāve been following for a long time. Iām about to order 30 of the 4.2 boards and Iāve not done anything with JLCPCB before. Am I correct in understanding from the quote above that if I upload the Gerber files and select the SMT Assembly option that JLCPCB will mount all the components on the boards for me (except for the ATTINY chip and the JST sockets)? Do I have to upload some kind of component list for them to do this or is it somehow included in the Gerber file?
OK, I see you have to add the two files for the components in the next step. Do the boards come ready cut individually or do they come as a board of several boards that you have to cut up yourself (if you see what I mean)?
Great thanks for that. I canāt seem to find a BOM and CPL file for the controller board, are there any? Also, Iāve been looking through farnell to order the JST connectors but there are so many to pick from Iām not sure which to get. Order code 9491902 seems to look right but I donāt want to order the wrong bits, can someone (who has ordered from farnell) confirm? Thanks.
I ordered the wrong pcf8574at. I ordered pcf8574t. I know Stuart said you can change address in code. Can someone point me in right direction ? Or should I order the correct one. Thanks
Hasnāt anyone in the UK ordered the JST connectors from Farnell? Also are all the JST connectors (on the controller board and cell board) the same? So for 28 cell boards and 2 controller boards 100 connectors should be enough.
100 connectors will be enough, they are all the same, the connector you selected from Farnell will work fine, I switched mine to a 2.54mm pitch (vs 2mm pitch) and they fit fine also.
Are you reading this on the web page or on the module configuration? The web page doesnāt store the new values it just sends whatever you specify to all the modules to do a bulk configuration.

Charging / Discharging Problem on higher currents:
Hi, I have also trouble with higher currents in the charging / discharging state (15A and above) ā the DIYBMSv4 controller lose connection. Iāve shorten all cables (crimped on my own), but it doesnāt help. Now, I twisted the longer cables (RX/TX form/to the controller) and it works (not testet with higher currents like 120A and above). Maybe you can see it in this photo:
