Felicity solar BMS for sale

[Quattrohead]

I could not get these BMS to send their data to anything other than EDMS software so not much good for monitoring, I ended up swapping them out for JBD BMS hence have these for sale now. As a BMS they are extremely good, they just don't like talking. All four were working when pulled and I have figured out the wiring, really being sold as spares but I guess you could graft them onto a self-built battery.
Let me know if you have serious interest and then I can give you more details.
