What's the efficiency of a battery-powered system in flight? E.g. disregarding ground charging and grid supply.
(edit) Wikipedia says ~95% for a generic electric motor and ~85% for a generic lithium-ion battery for a very rough estimate of about 80% efficiency in toto.
- walrus01 4y agoAlso depends how you have many batteries paralleled and the amp draw per cell, for instance a single Sony vtc6 cell might be ok for 30A draw for short times but will heat up while doing it. And needs cooling/thermal dissipation solution. The lower amp draw per cell the less is lost to heat.
