Hello, just curious about watts and volts an amp hours.
I have an E bike the Motor is 250 watts and the battery is 21AH and the whole System is 48 volts.
So just wondering what part does what, I think the 250 watts is the strength of the motor and that the volts helps the motor to be able to produce 250 watts and that the 21AH is to do with how long the battery can provide the volts to power the wheel at 250 watts.
I am 72 kg my bike is 34kg, I ride 52 kms a day on my commute to work, the ride includes a long steep hill that is ridden down and up and a couple of shorter steep hills up and down with many flat sections (all Paved road and Bike Path). My bike battery gauge has 5 segments and the battery goes from 54.6v down to 42v
The first segment lasts for about 49 kms or down to about 49 - 50v The most I have travelled on one battery is 80km but I have never ran it dry.
If all things were equal and the same bike, given that we are (legally limited) to 25kph, which combination would give best performance..... between 36v 48v and 52v ..... would It be worth getting a 52 v system with 250 watts, would the extra weight cancel out the benefit or would 36 v be adequate ?
Just wondering how much each component influences the performance the most ?
What confuses me most is that the Battery voltage it goes from 54.6 v to 42v why? it has a range of 12.6v ... am I reading it wrong why doesn't it go from 12.6 to 0 or something similar?
