This is a physical display that shows pack voltage, state of charge, state of Hhalth, and min and max cell voltage for an older REC-BMS balancer.
This balancer is used for charging FES battery packs for a LAK 17.
It also connects to a WLAN and exports a web server with the same information.
It's based on a TTGO T-Display running CircuitPython 9.x.x.
