small block - big block
short stroke - long stroke
small block, short stroke - 6-turn short can (ex. feigao 6S)
small block, long stroke - 26-turn short can (ex. feigao 26S)
big block, short stroke - 6-turn long can (ex.feigao 6XL)
big block, long stroke - 26-turn long can (ex. feigao 26XL)
Maximum motor power can be achieved either at max RPM or at max torque, but its value is constant at the same motor can size. (ex. Feigao S size rated around 600W, L size 800W and XL 1200W.)
Good compromise (Torque vs. RPM) is in between and based on application and driver preference.
Fuel efficiency goes toward electrical efficiency
Performance follows as well.
And with extra cell's you do the same thing as you do with turbo or super chargers, bigger injectors, better filters ... :)
