Sportster S NOCO lithium

Hello!

My buddy has been having some battery issues with his 2022 Sportster S and is looking into going the lithium route now. I run a NOCO in a few of my bikes and I looked up his Sportster but coming up short on what model would work for his bike.

Any Sportster S owners running a NOCO and can point me in the right direction?

Thanks!
