The writer of the forum post also mentioned this:
"My self imposed limits are based on what the cells return to after a bulk charge. For the first month, I was bulk charging to 3.55V per cell, they always returned to 3.295V on their own, so why try to force them. Let them be happy at 3.295 and "call it 100%"."
This would indicate 52.72 volts as the settle in point. That seems to be where mine settles in also. By the same chart, this would be 65 to 70% charge. Am I missing something?
