    Battery capacity testing (for 48v)

    I have used the bicycle for several weeks. I just dont have any experience of what 20AH is in terms of range. I use it hills a fair amount but I am just uncertain whether this truly is the correct value - it is a Chinese import after all/

    Battery capacity testing (for 48v)

    Thanks . I am considering another method but I am uncertain. The battery is for an ebike with a 1000W motor. The controller that I have also connected states that it draws out 26+-1A of current (the controller is rated to 30A i believe.). Is this figure indicative of maximum current drawn or...

    Battery capacity testing (for 48v)

    Hi I am trying to figure out if the capacity of my battery (48v 20AH) is true. I have looked at discharge capacity testers on you tube but am struggling to find any that would suppport a 48v battery. Could someone direct me to a device/method that would support this high voltage and also not...

    Does the angle of a drive train effect the efficiency of energy transfer

    I am clarifying what was posted on the thread. Both questions would provide a valuable answer to what I'm trying to find out.

    Does the angle of a drive train effect the efficiency of energy transfer

    Thanks for all the answers. So what I can take that there is a difference however it is negligible. I appreciate all the comments. Thanks

    Does the angle of a drive train effect the efficiency of energy transfer

    These arent bicycles they are the chainsets. The bicycle is on a flat surface but the chainset/groupset is at an angle and thus the chain is at an angle.

    Does the angle of a drive train effect the efficiency of energy transfer

    If the angle of a drivetrain in a bicycle becomes steeper - ie 65degrees, will it become less efficient in comparison to normal flat drivetrain?
