Can a low amps 48v battery handle big DC motor
The only way that a battery will limit the current of a DC motor is by the voltage drop across the natural internal resistance of the battery subtracting substantially from the battery terminal voltage. If that voltage drop is significant and sustained, the battery will get hot quite quickly. Letting the battery and interconnecting wiring limit the current may be ok if the excess current only lasts a second or so during starting. If it lasts longer than that, the battery will probably be damaged.

The situation described seems to indicate no chance of success.
