People spends hundreds if not thousands of dollars loosing weight from a car so better to optimize not adding it back when possible. Plus the car is already 54/46 and most weight drops happen in the rear making the cars around 57/43 or worse. Relocating all the packs among other things will help get to 52/48 or better depending on what else you do. That could be a 5% swing in weight distribution when combined with other mods.

To me this currently is setup as a convenience package for ease of install and getting to market quicker. I don't think it's an ideal solution all things considered.

That said, it's nice this is available and people who need it now and can't feel 14lbs off their car can rejoice. I think it would be nice if a more performance oriented package were developed that respects the cars potential.
Trunk dump reality:

A proper dual dump trunk location set-up would require a significant heavy duty fitment...it all sounds pie-ish until you get into the details.
First, to achieve the same V-drop 2/0 or 4/0 AWG is needed, the lugs for this size of cable is massive, so an insulated junction box in the trunk would be required so you could reduce to a 4AWG and reasonable terminal lugs to bolt to the batteries. Secondly, these large cables would need to pass through sheetmetal, hole drilling/corrosion paint/grommet or insulating boss, then a conduit system secured to the underside of the car to prevent sag or fretting or exposure to 'road-stuff'. Once you have snaked these welding cables to the engine bay another insulated junction box with a 250 AMP fuse and a reduction of gauge to utilize the Anderson connector is needed. Back to the trunk, drilling and mounting a tray and hold down system to properly secure 48lbs of batteries is needed. Once you get all these items piled on a scale.....100 lbs. I don't see the benefits

Also: Farad = 1 amp-second @ 1 volt. 3-4kW for 30 seconds = many F

Thanks, Rob.
