There were a string of problems with people running the vesc at 12s. IMO, I think its related to manufacturing decisions. I run 12s, chaka runs 12s, hummie runs 12s. There’s no reason it can’t do 12s, but it seems to increase the likelihood of problems, and with all the complaints onloop got, he’s probably saying 10s because it is safer than 12s. It also conveniently puts his customers in a place where they can buy his 10s battery (he doesn’t make any 12s batteries), but whether that’s coincidence or by design, would be guessing.
If I were you, I would buy the platinum. From my experience with enertion vescs, it’s not a question of if they will fail but when, and in mine and many others cases, it was within the first few days. Now your probably thinking, there’s still a warranty against manufacturing defects, right? Yes, but good luck getting onloop to agree that it was a manufacturing defect. If there’s any slightest doubt, you will be blamed for breaking it, as I was.
