Only wound to 50kv.

I heard on here it would only take maybe 50 amps at that kv before saturating and hoping to get that confirmed as I’m making the series connections for the battery.

Seems no way to know other than extrapolation based on similarly sized stator and kv or using a dyno, which I don’t have.

Yes, that would seem to be about right, 80100 130kV starts to saturate at about 150A and scaled with kV 150/130*50 is 57A, since the 83100 is slightly larger it can also go a bit higher. The saturation knee is not sharp so there’s no real limit that you need to stay within, i’d try at least 100A before worrying.
