Hi,
After being told my 72V system is not recommended and that I should work with no more than 50V-60V I wanted to discuss this.
Since all my components are compatible with up to 100V (CA, Phaserunner), and since with higher voltage I can expose all the wiring to less intimidating currents - then why not use it?
The biggest bottle neck on E-bike is the motor phase connector - which experience phase currents way over in excess of the 30A-45A those Andersons are rated for. Using a higher voltage system with a slower winding motor so you can keep the same top speed will solve this by requiring less phase currents for the same torque.
72V is also not yet a limiting factor with regard to insulation. For example, if I worked with 230V - I would have saved alot on copper weight (wiring only, not inside the motor!), but I would needed more heavy-duty connectors and insulations, not to talk about the danger of electrocution.
I really enjoy the fact I draw smaller currents to supply my 2000W hungry system, compared to if I fed it with 50V or less.
Any opinion about this?
