There is no minimum C rating for a current sink, just a max Amp that the power module can take. There's no link between them. A 5C 2 cell battery can blow the PM, but only if you connect enough components that pull that amount of amperage.
This is not related to C rating which is a function of the number of cells and the current they can supply. Personally i find it very confusing. Two batteries with the same 10C rating will deliver 30A for a 3 cell versus 20A for a 2 cell.
