Sorry I can't help with the exact details of the Daly BMS. One thing you could try is wrapping the balance leads through the clamp on meter jaw several times. That will multiply the reading. 30 ma and 10 wraps would show as 300 ma and may read on a clamp meter. If the 2 cells on both sides are pulling though, it may cancel out and not show much.
If you have a large balance difference like that, you will probably need to do some manual intervention. My battery bank was made out of 3 different modules that were at different states of charge. I ended up using load resistors and a charger on different cells to bring them into a rough balance before I left it to the BMS to do the rest. I got them all within 10 mv, but it took 3 days of my spare time to do 28 cells of 180 amp hours. For me it was pretty important as I was paralleling 2 cells in each position. They need to be very close or you can end up with a lot of current flowing between the two parallel cells. For a series only pack you do not need to be quite as tight before starting a charge cycle. Just find the highest cell, and connect a car taillight bulb and watch it come down to about where the lowest cell is. Then move it to the next highest, and work your way down. When you take the bulb off, there may be some bounce back, so you might need to do it two or three times. And be there watching it as you do it. In the case of my 180 amp hour groups, I was checking the voltage every 15 minutes at first, to get a rough idea of how fast they were coming down. Then I went to an hour between checks until they were close. I was only pulling 2 amps, so I knew it would take a while. I plotted a few points and found 2 amps would pull down 180 amp hour cell groups about 15 mv per hour. Once I had them all pretty close, I used a 10 amp e-Bike charger to charge the 14S string. Again monitoring the cell voltages. At 10 amps of charge current, my 180 amp hour cell groups would climb about 56 mv per hour. Every type of cell will be different, and they do not stay linear when you are close to full or dead. Li Po or Li NMC and such are pretty linear in the middle of the range. LiFePO4 are not as nice like that. They hold a much flatter voltage curve in the middle, and it can take a very long time to see voltage change between 20% and 80% charge. But once they enter the knee above 90% they can take off fast. I have not dealt with a large LFP pack myself yet, but I may be doing one soon. My plan is to bring them all to 3.5 volts as close as possible. Then run them all in parallel. And charge the whole bank of cells at just 1 amp or so. And have it stop at 3.65 volts. That should be a rock solid top balance. Leave them all in parallel to rest a while, and top them 2 or 3 times with the charger.
