  Quit futzing with it. If you're seeing > 13.8V with current flowing, that is evidence of balancing.

  How does it draw 0.14A if one cell hit OVP? The process was started at 13.8V which it was at for a week.

  So I set the voltage on the power supply to 14.0 volts, amperage to 5 amps, and confirmed voltage with my Fluke at 13.97 volts. Close...

  And verify the voltage with a trusted meter before reconnecting.

  Make sure you disconnect one lead of the power supply before changing the voltage. Adjusting the power supply while connected is a sure...

  Thank you for the link. I find it really interesting that this document was so hard to find given that calibration is something that...

  No it doesn't. What's happening is that the BMS engages in protection mode at some lower voltage while the EPEVER output jumps to 14.6V...

  Nope I’m saying at 14.6 we need to know if the BMS is stopping charting due to cell imbalances. A charger can sit at 14.6v all day...
