Is that even remotely possible even if the battery weighs 35 Tonnes ?
Finally how many electric cars can you make with 35 Tonnes worth of batteries?
That's an interesting point. What is the power deliverable from a discharging battery looking at a charge/rate factor? If the battery is below say 25% charge, can it deliver at the same rate as a fully charged battery? What are the consequences for aircraft? Would it be necessary to look at a battery with 25% (number drawn out of the air) as less able to deliver energy to electric motors? How would this affect things such as reserve power and ability to do a go around?
