Imagine an EV SR71... yea, exactly, gay.

False.
Actually, I'm glad you brought that up.
Since the purpose of the SR-71 was stealth and speed, yes, if it could have been electric, and met all the other parameters to fulfill the mission, that would have been better. No jet noise, no jet heat signature. Both of those caused major headaches for the program. But there isn't battery pack in the world that could fit the bill, and one of the uses of the fuel was to balance out the center of lift vs the center of gravity over the range of its speed. And since no electric motor has ever been made that could provide that kind of power in such a limited space, those are all deal killers.
But you want to know what part of the propulsions system was electric? The inlet spikes. Those have to retract/extend over a nearly one-meter length, to maximize the engine's efficiency. They were the key to the whole damn bird being able to accomplish its mission. And that mechanism was powered by electric motors.
And yes, even if the bird had been electric, they'd still have had the spikes, because the idea was to recapture the aircraft's own otherwise lost energy created by its own shockwave, and reclaim that energy by heating the air in the engines even more than just the fuel alone could account for. Electric or internal combustion, the spikes would still be there.
Guys, if you like the noise of ice, more power to you. If you want to go fast, and be the fastest, you'd better start brushing up on your studies of electric motors.
Get it? "Brushing up?" A bit of engineering geek humor for you, there. No, in reality multi-phase/multi-polar is probably the way things are going to shake out for electric, so y'all probably might want to study up on some trig, as well.
