EDIT: after a quick search, the largest seems to be the golden-crowned flying fox (Acerodon jubatus)
if you trust Wikipedia (an encyclopedia of any sort is only a good starting point for research, IMHO, YMMV)
here is more info on size of fruit bats than you may want to know:
Pteropus - Wikipedia
it states that a different fruit bat is largest:
"
The large flying fox (P. vampyrus) is generally reported as the largest Pteropus,[1] but a few other species may match it, at least in some measurements. The large flying fox has a wingspan up to 1.5 m (4 ft 11 in) and five individuals weighed 0.65–1.1 kg (1.4–2.4 lb).[11][12]
Even greater weights, up to 1.6 kg (3.5 lb) and 1.45 kg (3.2 lb), have been reported for the Indian flying fox (P. giganteus) and great flying fox (P. neohibernicus), respectively.[1][13] The black-bearded flying fox (P. melanopogon) is massive and may be heavier than all other megabats, but exact weight data are not available.[14] Comparably, no full wingspan measurements are available for the great flying fox (P. neohibernicus), but with a forearm length up to 206 mm (8.1 in),[13] it may even surpass the large flying fox (P. vampyrus) where the forearm is up to 200 mm (7.9 in).[11]
Outside this genus, the giant golden-crowned flying fox (Acerodon jubatus) is the only bat with similar dimensions.[1]"
I think this is your bat:
https://en.wikipedia.org/wiki/Black_flying_fox:
"The black flying fox has short, black hair with a contrasting reddish-brown mantle, and a mean forearm length of 164 mm (6.46 in) and a mean weight of 710 g (1.57 lb). It is one of the largest bat species in the world, and has a wingspan of more than 1 m."
