Are you talking about this diagram? It's possible to change the position of the wires to connect JST. Use a needle to push them out and then reposition them.

For my part, I flash the ESP32 or ESP32-S3 from the command line from Linux without any problems and I don't need a web interface. I find it very simple. When the firmware is compiled, the choice is offered to upload it via UART or IP. esphome run jk-bms-can.yaml To flash an ESP32 already in...

I'm currently working to finalize the multi-bms version with everything connected on a single ESP32. This is mainly intended for the PVbrain2 card but this should therefore work with 2 or 3 BMS and a classic ESP32 (to be tested). https://github.com/SeByDocKy/pvbrain2 Thank you for the links...

Not having an Atom S3, I cannot develop or test anything but there is already code available and tested by @arzaman. This will be part of the new packaged version. https://github.com/Sleeper85/esphome-jk-bms-can/blob/development/packages/device_atom-s3-display.yaml

Thanks, that’s interesting. @arzaman and @Der_Hannes can you share your procedure? I could then do a how to in github.

Thank you for taking the time to document your procedure.

OK. Sorry but I don't have Atom S3 board.

These are functions that help prevent OVP from triggering with an unbalanced battery or with runner cells. If your battery is well balanced and of good quality then it is not necessary to activate these functions...

Yes 0.003V is very low, default is 0.01V. I personally use 0.005V.

In addition, with a charging voltage of 54.2V, the cutoff amps is close to 0A, see the links cited above.

Because one of the end-of-charge conditions is that the equalization of your cells is completed, which is not the case.

With switch balancing enabled, charging only ends when your cells are equalized. Delta cell V. must be smaller than Balance Trigger V.
