Request: SmartSolar 250/100 with ~80v system voltage

Looks like according to the docs and some forum searching here that the max battery voltage of the SmartSolar 250s is around 65V. (though the Docs don't specifically mention the max adjustable voltage)

I have built an all electric 1947 Crosley with a battery voltage of 82V and would like to park and charge this under my 5kw solar car port. I'm sure my use-case is niche but doesn't hurt to voice my needs! I'm currently an all Victron home and hate the idea of having to find a different manufacture!

I am not able to go beyond 69,59 Volts at absorption voltage with a 250/100.

So 80 Volts are not possbile with this charge controller.

theoretical question: two mppt in series connection would do that?

for example: 2x 100/20 (48V) would send 96v max to batterie...
