Hi I was hoping some one might help , my bike got taken by the wind , by the time it finished the main controller broke etc,etc , so now I have a new controller fitted , everything is ok , but my controller does not register the battery indicator , on the battery if I press the button the indictor light gives a reading of how much battery is left . Any help on this would be good . model of bike kalkhoff endeavour impulse S10 2015 . Thanks Eugen
