They need a moderate spike to get the motor moving, then a steady current to keep it going.
E.g. my ebike is 250W @ 36V. That’s 7A at full (continuous) power. A lithium ion battery can be discharged at around 10C while a lifepo4 battery can only do 1C discharge. My 13Ah battery could handle it, even with the 20% capacity loss at 0.67C (7/(13*0.8)). A 500W version would exceed the battery rating however, if it’s lifepo4, while being fine with lithium ion.
Basically, lifepo4 batteries could handle a low end ebike, but would likely still want some super capacitors for spikes. They would need to scale up significantly in size to handle more powerful motors.
Oh im learning something! Ill look into this!
