42OhmsPA
What's in a title?
If I remember correctly your voltages yesterday were closer to 3.3xV?So I disconnected solar and waited a few minutes. The gap between lowest and highest had been almost 100mV previously, it was down to 60mV now. How could it get there when it was so well balanced last night?
That is the flat part of the curve, voltages will be very similar with potential large differences in capacity.
There is always user mode.And batteries 2-5 only show 53.4V
So, I swapped batteries 1 and 2. If the old #1 wants to throw OVP, let it be, but don't stop the charging of 2-5. No, I didn't move those heavy boxes. Just flipped 4 dip switches and moved 2 comm wires.
Too dark now to measure anything but hopefully tomorrow.
