In theory, a LFP battery should last at least a decade and it won't corrode your engine bay. Funny thing is, in all the benefits Antigravity listed, they didn't mention that a tub of acid will corrode its surroundings with just its off-gassing. Even if it never leaks, just its presence will rot away your car.

Anyways, I did not pay the Antigravity price. I actually just purchased two, one for my Z and one for my Model 3 as well. I paid $275 US with shipping for the Z one. This is a direct fit replacement for the OEM physical battery size, I hate how sometimes you see people with undersized lithium battery casings flopping around in their battery bay. I already have experience with this manufacturer, as I purchased one of their batteries in 2018 for my motorcycle and it has been great. I will post about it with photos once I receive it.
