It looks like 28s nmc is what you need. The 94ah SDI cells are the most flexible as far as physical layout and fitting into available space.
Well proven for ev use, Gems in particular.
Pricing comparable to our most popular Gem battery. 80v 22s SDI module. $2750
If the 22s module fits well, you can easily add a 6s module to it.
A little less than 10kwh and 65+ miles range est.
