Yeah, I need an ESC capable of 10s (12s preferable for a little headroom) AND high currents over 100A. Not too many of those around at anything resembling a decent price. The HV-110 is my other choice, but it's only rated at 110A with not much current burst headroom (typical of air ESCs). And MM is right, the 110A is already stacked so more stacking makes for a large ESC, not to mention pricey.

With the Sentilon's single board 100A layout, adding an extra layer should be fairly simple. And would give me a solid 100-120A continuous rating with extra room for bursts up to 220A. Even buying two of them and modding for stacking is still pretty cheap at $200. Can't even get one HV-110 for that price. I too don't know about the warranty cost for the cheaper ESC, but for that price, I'd take the chance if all other features work for what I want. And TBH, I don't use all the programmability of any of my ESCs, so that's not too important.
