Hi all. Does anybody know if the controller will work if i add a 48v battery to my Ecotric26 instead of the 36v battery. The S900 display can be changed to 48v but i dont know enough about the controller. Will that need swopping and if so, what make and model would i need. The motor is 500w.
Thanks.
Andy.
