I know some HyperFat owners use Grin Technologies PhaseRunner and Cycle Analyst.
Somebody here on EBR posted, but I can't remember who it was. He was not the only one, there are few HyperFat owners running PhaseRunner because stock 35A controller has overheating issues.
Personally, I think the PhaseRunner is overkill with 72V capability with max current of 96A.
The BaseRunner likely would do fine, but I can't speak from my own experience. All I know is that HyperFat owners are happy with the PhaseRunner.
