The caps are just one part of the circuit. The FETs and other support components are another limiting factor. The "brains" are powered by the internal BEC and are probably the same for all BK's ESCs so that's probably not a factor.

Another theory: Caps are generally rated for certain voltage ranges. I've seen them at 5v, 6.3v, 10v, 16v, 25v, 35v, 50v, and higher. 20 cells is way too close to 25v to use. 35v rating is still a little close IMO since circuit designers tend to use caps that are rated at least 50% higher voltage than the working voltage. The next step is to use the 50v caps...
