Hi Jay, as I see it there are two problems with parallel. One is the burnout of the FET in one of the controllers, and the other is the "not knowing what the other is doing. The burn out is caused by the capacitors in one CC supplying a surge current to the other CC. I tried this and it seemed to have success. However, I do not know how to trick the two CC to be both in absorption at the same time.
