Hi all, finished building my 18s6p P45B pack and did my BMS wiring yesterday. I am using a JBD SP22S003 BMS and everything seemingly went fine except for my final readout. The diagram shows leads BC16-17-18-19-20 as getting combined, however on my connector there is no lead for where BC20 would be - it skips and has the last 2 leads. I combined the 4 wires 16-19 and finished it off per the diagram, however I am getting an odd readout on the Xiaoxang app. Not sure if I should add a lead where there is one missing, and add it to the other combined leads? Even though the BMS model number is SP22, it’s listed as a 21S BMS (and the missing wire would confirm that also).
Any thoughts? Thanks in advance and happy holidays all.
