Lightweight battery alternative

[razorlab]

Looks like there might be another alternative now. While I have not been a fan of Optima batteries in the past, seems like this new tech could be promising.

OPTIMA ORANGETOP Lithium Car Battery, QH6 - 880 CCA, 45ah

And nice to see Bimmerworld has had a role in development with it

I believe @garudathree has a variant of this in his new M2.

Is that what he’s tracking now? Curious how the S58 does on track with almost 4k lbs of weight, and how hard he’d be pushing, at his level.

Has anyone looked into ordering a comparable battery of this type, Lifep04 lithium ion 60, 80, or 100ah thru Alibaba?
I've gotten quotes for $400-$460 landed stateside.
Has all the same features. Only concern is the BMS programming. Wonder if there truly is a difference in programming between the generic OTS BMS and batteries like Powertex or Antigravity.
