Hey!
Max voltage is going to be 24S or ~100V. Currents up to 350A should be no issue with water cooling but you'll need some high performance thermal interface materials to connect fets to water block. It's not the easiest task but is certainly doable. You probably won't run into pcb overheating issues with battery current up to 300A with standard copper layer thickness. For higher currents you can always use thicker internal layers (3-4 oz). Using a rectangular copper busbar also opens another point of thermal connection to heatsink. It will cool the pcb which will increase the limits but also cool the capacitors.
Vesc firmware is limited for my hardware config. The limiting factor is the maximum current shunts are able to measure which is I think 412A. You can further increase this by choosing shunts with lower resistance (like 150u) and modifying the firmware slightly.
I don't know what kind of axle it was. It was from a qs205 clone from aliexpress I think.
Hope this helps!
