I have a vague memory of having to change the pinouts on the bms cable from the Lux to the Pylontech "c" series battery on my sons system
when i gave my son my acs3600 and he bought 4 x us3000C battery's.
So i think you have to use the new battery as the master with the adapted bms cable and link the rest with the standard cables.
in a bit of a rush this morning so couldn't find the pinout diagram so cant tell you what they are.

I remember reading that, that they changed the pinouts on the C series. So if original all running B's or plus and trying to use original back to inverter comms cable and C as a master it can't communicate. Or in other words, exactly as Tinkering said, sorry got excited there.Tinkering wrote: ↑Mon Oct 17, 2022 9:00 am I have a vague memory of having to change the pinouts on the bms cable from the Lux to the Pylontech "c" series battery on my sons system

Re: Adding Pylontech battery ….
I think you are in the right area here. As this morning, after having slept on it, I reviewed everything I’d done and ensured the cables twixt new master & first slave were the ones supplied with the 2000Cs. I didn’t change anything. Powered it all on & hey presto - it all worked first time! Lux units recognised straight away & the portal showed 125 amp charge/discharge rates. We’ve been blessed with a sunny day here today, so my expanded banks are now 100% full.Tinkering wrote: ↑Mon Oct 17, 2022 9:00 am I have a vague memory of having to change the pinouts on the bms cable from the Lux to the Pylontech "c" series battery on my sons system

The final, and somewhat bizarre twist, was that I thought I’d check on what the battery lead time was from my supplier (I had to wait a couple of weeks for these), not only had the delivery jumped to 12+ weeks, but the price had increased by over £200 EACH!
Hey ho
