Disclaimer: This is a hobby , I have put in the hours with the proper people but the license is expensive to maintain . So .. I'm just posting what I'd do , if anybody wants to copy me , that's on you.
(and NEVER forget I yam the Weirdo Overlord and possibly an alien sent to prove right "Ain't Right" so , should you even think of copying me in the first place ?)

I assume you mean at the battery not between the battery and controller...
I'd put it at the battery ground post. That would leave the least amount possible still live. Protecting all the way to whatever device is being powered..
Then disaster fuse , shunt , system ground buss in or next to the fuse box for your house circuits.
On the battery / controller wire ? again , as close to the battery as possible.

Thx for making me think about that , reminded me to remove the chassis ground on mine . I'm not going to parallel the LI up with the LA starter battery and alternator anymore . Going to try all solar charging with Mr.Red on BU as always. Helloo Wilbur !

Need a hydraulic crimper but expensive for a decent one that does bigger than 2ga.. I've been using the crap one at my auto parts place . I got all my switches ,fuses, lugs , heat shrink and 10 ,8 ,6+2 ga plus some Anderson SB 50s there too so I have tool access.
