Is that graph you posted showing battery amps or motor amps?
Another idea i had, would it even be a viable option if i made a 7.2V LF battery rated at 85 ah and placed it in series to boost the voltage up, so the controller now sees a 48v? That all seems a bit clunky to me, i'd have two seperate BMS? two chargers?
