Welcome
I really appreciate your support.
About overcharging a single cell (1/48 cells), I'm with saptzae, it's voltage limited.
About a bad single cell (short) I'm fully with you!
Let's say one cell out of six in one of the eight "cells" goes short.
The remaining 5 cells will deliver max current in that short until they are dead or the short cell is on fire. The BMS CAN'T stop this. It's an internal process out of reach for the BMS/Charger.
