Where this data comes from
The size is the housing's, not a pouch's: 105x35x31.5 mm around a 550mAh 4S is 0.60 g/cm3, a third of what a pack of cells weighs for its volume, because this pack is a moulded, vented shell with a latch and slide rails that only the Defender 25 accepts. iFlight's own page states the same 105*35*31.5mm (and the same three figures for the 900mAh version at 100 g - a size that does not move with the capacity is the enclosure's), 70+/-2 g, 8.14 Wh, 4S1P, 60C and XT30, so every figure here is the manufacturer's as well as the retailer's
