So you think a battery not disintegrating if you pump energy into it isn't a durability feat? Lol.
Let's take a car battery. You think you can pump a supernovas worth into it over ten minutes without it melting??
How about two supernova's worth? A hundred? A thousand? 2 thousand? 2 million?
Lol. You need to stop and think for a second what you're saying.
