Seems like fun. I thought about going with a 48s or higher, but only real good use cases for that I can find is inverters (or cars). Looking at a high power RV type setup, and even 48v seems alittle useless, as the only time I plan to run the inverter is for meals, everything else would be DC, and not much stuff will run off 48v DC even. All the fridges and HVAC units I found for DC are 24v or come with a 48->24v adapter :( Only real goal for going higher voltage is weight savings with all the wiring, and less bms parts to deal with.
Bonus another car to work on lol I always wanted to feed a battery power into a charge controller to see how it performs and just charge the battery direct from the high voltage solar panels I know sounds stupid but I always wanted to try it a two battery system high and low voltage maybe one day if I am bored. Thanks for the update.
