I need to do 16km a day with hills and currently it will only do 4 before needing a 2 hour charge, and i need to push it up the hills. Looking for the best option to upgrade to. Probably changing to a pair of 6cell 5000mah Lipo batteries to aid in charging speed as they will charge in an hour. Just trying to workout if they are too small.
16km you will need atleast 10ah.. anyway , the controller is the choke point for wattage , so changing the motor doesnt really do much;./. assuming the smaller motor was using the full wattage provided by the controllr/.
