Maybe someone will indulge an ignorant question: Is there any reason someone couldn't make a cargo E-bike powered by a car-battery, or a marine-battery?
Of course regular E-bikes need a battery with a slick form factor, but a longtail or a bakfiets could fit a big rectangular box somewhere in the cargo space. Are there electrical engineering reasons why I've never seen this done?

- pomian 3y agoYou can use regular'car' batteries. The problem is only in the amount of power they provide by weight. Lead acid batteries can only deliver about 15-20% of their full power (these are example numbers not precise.) So let's say you can go full speed but only for ten minutes, then slower and slower. Lithium batteries can provide about 80% of their full power, so same vehicle as above, but 60 minutes of full power. There are of course lots of other pros and cons to available batteries.($$$) But range to weight, is the most basic.
