Hello all,
I recently made a new battery for my scooter, a 20s4p 84v pack. My scooter is a Ninebot G30 with hub motors on the front and back. Im using two flipsky 75100 vesc's with the fet's mounted directly to the stock controller's case. My issue is I was expecting the motor to spin twice as fast, or at least somewhat faster when I doubled the voltage, the only reason I made the 20s. However when I use the 20s battery the motors still spin at the exact same speed. With the 10s they spin around 18mph and the same at 20s. Im using FOC mode and with update firmware. When using feild weaking the 10s can spin the motors at around 21mph and the 20s can get up to 35mph. I had a previous ebike and with a chinese 12fet controller and the more voltage I gave it, the faster it ran. I thought It might be due to a ermp hard limit or somthing, but from looking at some data I am far from the limit. I also set the voltage and current limits far above what I was at, so I dont think that is an issue.
Does anyone know why this is?
Could this be related to the 75100, or maybe the stock ninebot hub motors?
Any advice is much appreciated.
Thanks.
