The first top balancing of the Frankenstein Battery took me while. I had underestimated that some of the cells had a far lower SOC than others, even initially charged to the same 3.45V. It took me several hours to reach an acceptable result and balanced all 16 cells above 3.6V.
I explain why this battery is actually no different to any other battery we have built before and what we can expect, if we try to balance the battery at the bottom to make use of the remaining capacity of the 304Ah cells.

This out of the way, it is time for the first capacity test of the Frankenstein Battery. Which cell will be the weakest one and determine the overall capacity? The result was certainly surprising for me...
