The ability of the motor to handle the cells is dependant on its Kv value (a 5000rpm/volt motor can't take 32 cells, as the rpms would be too high for the motor or controller, however, a 1200rpm/volt motor can easily take 32 cells without over revving). This goes for any motor (Wanderer, Feigao, Lehner, etc.). Amp wise, I think the higher the cell count (using an appropriately "cooler" motor), the less the need for a high amp controller. Most of these motors are most efficient in the 30-40000 rpm range, but they can all take a lot more rpms. The Feeigaos are limited primarily by their bearings (I have exceeded the rpm limit on several Feigao motors without issue).
