Byd powerwall qnbbm unbalance wave
#10
I was too quick to blame the cause of the wave pattern on the qnbbm's, they were added the same day the i finished the battery cell interconnects. Didn't cross my mind that the interconnects could cause the wave pattern in the balancing..

 After doing a complete discharge (1350ah out) down to 3v the batteries stayed within 20-50mv until the end, then drifted to 70mv, no wave pattern at all. The wave pattern started to form right away on recharging the battery bank on 200amps of solar. I do not think the little amount of balancing the qnbbm's provide could sway the balance with 200amps going into them, 16amps each . After the batteries are finished absorption the wave pattern goes away.. most balancing I have measured from the qnbbm's is 550ma..
