Max Charging Current of typical GC2 battery
Say the GC2 battery bank has been drawn down to 25-50%, what will be the max current they will initially accept? For sure it's greater than the ~24A max my solar charger has reported as that was l...

I'll give you a pro tip here and it's for Trojan T105's
but is applicable to other GC2's if used with care..
it's all about max heat capacity, for a T105 the best figure I would use is 0.05 watts per Ah. a T105 has an internal resistance of 0.003 Ohms . so that's 0.001 Ohms per 2 volt cell.
The max thermal charge limit is square root of (.05 x 225Ah) / .001 = 106 amps. yes.. you can charge a T105 at this rate..
this is approx c/2
I wouldn't advise you do this often, but it can be done.
