    5amp charger battery degridation

    Will a 5ah charger used everyday on a 48v lithium battery degrade it noticeably over a 2ah charger? degrade it meaning less run time, power output etc. I have a 10ah 48v battery and it only takes 2hrs to charger on the faster charger but is it hurting the battery? Thanks :)

    Voltage drop

    Hi all, is it normal for a lithium battery to drop voltage as is being used? Just one of my bikes, has a 48v 15ah battery and according to my multi meter it starts of at about 52volts but after about 20km it drops to about 48ish volts and I can feel the power drop. Thanks :)

    15ah vs 10ha size

    I have a 48v 10ah battery or so I was told, but wanted a 48v 15ah battery, but the replacement battery that was shipped to me is smaller and by quite a bit. Is it possible for the larger capacity battery to be smaller? they are LifePo4 batteries I'm pretty sure. I think they are headway...

    changing contoller for more power

    I just installed a 48v 15ah 1000w front hub set up on my bike, correct me if I'm wrong but to get more power its just a matter of changing the controller to a higher out put unit? so keep everything else and just change out the controller? What are the pros and cons in doing this? Thanks :D

    9C front hub question

    I have a 9C front hub on my bike it was sold to me as a 2000w motor, what puzzles me is that on the side of the motor is a long number with letters, the following JZ36V500W110615009. Its the 36V500W part that I don't get, that must mean 36volts 500watts? but its a 2000w motor. I have a 36V 500w...
