Pseudo self-discharge exercise

WHELP! Something has changed.



Prior self-discharge tests saw a dramatic drop in SoC with a voltage drop from 13.27 to 13.15.

Now, after much longer, I've not seen the voltage drop OR the SoC drop, so reloading the overkillsolar defaults must have changed something... or maybe I just need to wait longer, but that's not happening...

Now I'm going to break this bugger down and use the 4 new Topband cells to build an 8S battery! I only have a dumb BMS for this one, but I'll be getting a new JBD with my 280Ah cells that are on order from Amy Wan. Going to use VRM to monitor the battery of my PowrMr...

I noticed on the Overkill ap if i turn off and on the charge or discharge switch it resets SOC based on voltage chart

Nothing like that here. The BT module is disconnected. The only means of communicating with the BMS is via VRM.
