The only purpose of a fire extinguisher is to allow you to get out. They do not contain enough water to adequately put out any real life fire (especially not an electrical one like this).
If he can't reach to grab it because it's too hot, he should have already left.
I hope it doesn't contain any water at all!
Dry Powder or CO2 is what you need for energized electrical equipment. And considering there's potential lithium involvement, you might want something more specialized (e.g. F-500 Encapsulator Agent). I agree anything more than a small-scale incident you're just getting the heck out of dodge. I'd have built something along the lines of a concrete bunker, with an automated suppression system to buy time.
I think I'd rather have the extinguisher near the door.
If you are outside, it does not tempt you to cross the room. If you are inside, you run for the door, and then turn around and decide if maybe you should just keep running.
