Hi Guys,
Would a different controller allow, by adding a second 36V battery and the appropriate switches, the bike to run as either: (1) 36V or (2) in series at 72V?
I read a post that I understood as suggesting that my brushless motor can likely handle 72V. This Prodeco Phantom X3 e-bike has an OEM 500W brushless motor in the hub of the rear wheel and was designed for 36V. Various pictures are below.
I'm imagining that I could chose between a long-range 36V slower bicycle or a really fast bicycle shorter-range extra-fun bicycle.
The OEM 36C 16Ah battery has been replaced by a 36V 10Ah battery. Currently it's speed limited to 20mph. I'm turning it into my SUV - local cargo hauler and recreational traveler. I intend to buy a second 36V battery for longer trips. I already have a heavy duty 40A switch so that I can run the second battery after I've used the first.
It's got a twist throttle. It has no LCD display, no sensor for pedaling torque, and no brake sensor. I have ridden motorcycles for decades and am confident without any of that.
The only connections used on the current controller are:
If I can use a different controller to run both 36V and 72V, what controller do you suggest?
Thanks!
Joe
(BTW I understand that by adding solder to the shunt, I could increase torque, but probably not top speed.)

The only connections used on the current controller are:
- Two wires (red and black) to battery
- Four wires to twist throttle that has 3 lights to show battery status
- Nine pin connector to the hub motor
