Oh man you saved my butt. I just attached them and raised it up to the max. For the past 10 min. Hopefully it isn’t damaged. I measured it and it only showed 3.42 on the multimeter while it was connected so hopefully it’s good. I checked them without the connections and they were 3.36. Now 3.42 again with the bench power supply set at 3.65 before connecting. Now it shows 3.6v going in at 10.4ampsJust want to urgently reiterate something mentioned earlier, because it sounds like there may have been potential for a mistake amidst the confusion:
Set the power supply to 3.65V with the power supply DISCONNECTED from the batteries. Then connect it and DO NOT touch the voltage again.
If you adjust the voltage while the PS is pegged at 10A, you're increasing the max voltage the PS will provide but it won't show up on the screen and you have no way of knowing what it is. If it happens to exceed the max voltage of the cells, then when the cells get full the PS will just keep going and damage the cells.
