Hi everyone,
I want to make sure I am choosing the right battery for my electric motorcycle/e-bike.
I modified a 125cc old cafe racer into electric motorcycle, I've already collected all parts that I need for my build.. except the battery
My motor is the 3.5T 3000-5000W QS Motor, the input Voltage Range for it is 48V/60V/72V, MAX DC current: 100A Max Phase current: 250A
My controller is the Sabvoton 100A, suitable for 48V/60V/72V
MAX DC current: 100A Max Phase current: 250A
My bike weight is gonna be around 50-55kg (without battery)
I weight about 90kg so the whole bike with rider is gonna weight about 140kg.
I'm looking for a battery that's gonna let ride for about 60-100+ km on one charge.
Should I go for 72V battery or 48V is gonna have satisfactory top speed with 140kg weight as well?
How many Ah should I go for to get good range?
And the most important question for me is - should I look for a battery with 100A current or lower current is gonna be fine? Is it gonna be bad for the motor to - for example - put 80A battery?
Thank you so much for all your help!
