Hello,
I am thinking about purchasing a 3000w ebike kit off of Amazon. It is specified that the motor supports a range of 48-72v, and that the controller is 80A. While looking at batteries I could use I ran into one with a 60A BMS. However, after asking the ebike kit's manufacturer they said I could only use a battery pack with a constant 80A rated discharge (which conveniently is made by them, has half the lifetime, the same capacity, and is more expensive). Doing simple math tells me that 72*60 gives me 4320 watts, which is way more than I need for the 3000w motor I have. Does this mean that I can use the 60A battery without worrying, or is there some issue I've overlooked?
Cheers :thumb:
