Item number 4 under 9.3.26 which allows rotary molded cells not having a bladder, or not contained in a metal can in classes (IT) that are not required to have a cell but are allowable as an option.

I most certainly read the earlier part as if a cell is required it must meet the specs, but in classes where they are not there are no specs, especially with the rotary moulded (cheap, no SFI or FIA)cells allowed.
