12S BMS Needed

[IH1972]

I'm looking for a 12S 40A Jiabaida BMS to use with a Lifepo4 pack I'm putting together.
I've been very happy with the 16S BMS I bought several years ago in the photo, but the seller whom I purchased it from is no longer on eBay.
I'd like to find one that is Bluetooth compatible.
Any recommendations for a supplier?
Thanks very much!

One other question. Would it be possible to use my existing BMS with a 12S pack instead of the 16S pack that I bought it for?
I found some information online that suggests I could. If so, what happens with the balance wires that were previously connected to cells 13-16? Are they simply not used?

It depends on the model. I have seen several different ways to use fewer cells.
My guess would be you tie all the unused balance wires to the B+. Most won’t work if any wires are disconnected.
If you can read any chip numbers on the board it might be possible to know for sure.

It's the model shown in the photo in my first post.

I can't really tell from that. The aluminum cover hides everything.
Maybe if the cover was removed it might show.
There are datasheets on their website. It looks like that model uses the UART to program the settings. You would need their software.

Sounds like I'm out of luck.
