I don't work in the field but just to kind of put it into perspective, a 12v 100A LiFePO4 battery has 1200 Watts capacity and weighs 30 pounds. A typical gaming PC (which to be fair, is more willing to trade power for performance) consumes about 600 Watts per hour. Problem for a Tesla? Not so much. Problem for a lightweight drone? Definitely.

ahhh the units in this post are making my eye twitch.
I would be mad too, if my gaming PC was demanding 300 Watts of power but it took half an hour to ramp up ;)
I know Watts per hour is not the right way to phrase it but I feel it helps for those that don't know. Also, I just don't like saying Amp. Hours :)
Watts per hour implies watts/hour. Watt-hour implies a number of watts multiplied by a length of time. Also known as energy. Watts are power. Watt hours are energy. Two different things. Watts/hour is nothing.
Watt/hour is speed of power. It doesn't make any sense.
No, you misunderstand what it means in that case. Watt-hours are comparable to joules. 1 watt-hour = 3600 joules.
watt*hour=joule

watt-hour: you cannot subtract time from power, it doesn't make any sense.

watt/hour: delta of power per time, something very weird.
