I have the same charger as you have and even though I have set the discharge rate at say 23 or 29 amps depending on what type of battery I'm using it usually never gets up to that maybe it has to do with it detecting what are packs like or don't like. or something to do with the IR. I even run the Orion 100 C shorties and saddles So I know the packs are allowed to discharge at higher rates
