Well I changed my idea just a little,  to do that I would have to shut down the system, disconnect the BMS and go through the procedure again checking wiring etc. Just reminded myself that if something is working well, leave it alone, so I left it all running and connected the Active balance leads to the battery link bars, could have drilled and screwed onto them but just opted to solder the wires into the exposed copper bars. All the these white plastic batteries in the shed are in a large steel lockable Toolbox, Mounted the active equaliser into the inside of the toolbox plugged it in and it started working, checked the setting on the (old) phone app and it looked the same as the usual BMS, settings all over the place and only the balance light on, sounds about right. Most notable was the cell voltages were very stable and not bouncing allover the place, will connect it to the PC later and see how it works out, its just an experiment.       DALY BMS cycle count (if its real) since installed February 2021 , shed battery 121, 1st house battery 271, 2nd house battery 119 all of these 200Ah each.
