Battery relocation for HANDLING (not drag) - best spot to mount?

I’ve never used the factory jack. I don’t trust them not bending my bumper. Any distance I bring the smallest HF aluminum floor jack. Or I’d rather bring a small bottle jack and wood blocks.

I have an aluminum Ford donut spare with center opened up.
Lol, Yeah well your perspective isn't the same when you're 18 as it is when you're 50.
