I’ve currently got a perfectly operational system using the REC Q BMS and an 8S4P configuration.
--- right now connector pin 1 is at the main negative terminal of the original battery configuration, and bms connector pins 2 thru 9 are attached to the 8 different cell positive terminals, lastly connector pin 17 is on the master positive of the original battery configuration.

I am doubling my battery capacity by adding on a second 8S4P battery configuration.

Am I able to just remove pin 17 positive and then add the new 8 positive cell wires into connector pins 10 through 17?

Does the bms require that each cell connector pin increases by a single cell’s voltage in series or can this second battery be added in the above manner?

Thank you!
