Earth connection under the front seat

[Sp0_0k]

Is there a decent existing earth connection under the front left seat for 50amps draw?
I plan to route a positive cable from car main battery to charge lithium batteries at 40amps min so need to find a decent negative connection on a body. Somewhere around left seat.

Weird that connection to a leisure battery is rather thin cable from a factory and it draws up to 80 amps.

Apparently so. See here.

Is there an earth I can use under passenger seat?

Trying to hardwire my Blackvue battery that is under passenger seat. I got positive supply from fuse box. And found a suitable earthing point on the seat base. It has continuity to earth. i.e I am find it with a multi meter in any metal part. But I am not getting a power feed due to no 12...

Seat base bolts are a usually good earth point.
