To power two hub motors with the same throttle, you will need two motors and two controllers, and you can hook them all up together using a cycle analyst and a dual shunt. That way you can have a single throttle, control buttons, etc.
You can use one battery, but it has to be able to discharge 50 amps. Our 52V 21Ah battery pack can handle this, link below.

Otherwise, you can connect two batteries to the dual shunt.
You can purchase the cycle analyst below. Make sure to select the "Dual Shunt" option.

The dual shunt will connect the one/two batteries to the two controllers and to the cycle analyst (which will connect to your throttle).
This video goes over the wiring to hook up the Cycle Analyst 3 with the Magic Pie, and how to add a PAS sensor. Connect the green and black wires from the throttle to the cycle analyst and from the shunt to both controllers instead of just the green wire as shown in the video. The brakes can also be connected through the cycle analyst with some splicing required. The brake positive voltage and signal wire can be wired with the 2-pin cycle analyst plug.
