Very interesting chart, thank you for posting that. I wonder how similar my GBS cells would be compared to the Winstons. If you look at the chart I posted, 3.35vpc would be about 28% SOC at 0.5C while a .05C charge on your chart could be 65% SOC. Goes to show why you can't rely on voltage with LiFePO4 cells, which makes it a little more nerve wracking for newbies like me.
These are the only settings I can adjust in my solar charge controller. Do you see any problems with these settings?
The charger was only matching the 0.8 amps being pulled by the BMS, contractors & LCD screen, according to the shunt-based reading and I confirmed with a clamp meter.
