Mamba Max LVC issues

[BrianG]

Well, it sounds like the firmware isn't set up for 5s to me (from lack of LVC choice). Isn't there an auto setting? Dunno if it even works for 5s though...

But yeah, you're asking a lot from an official 3s (unofficial 4s) ESC. The FETs are probably fine, but I'd be more concerned about those 25v caps - 4v of headroom is not a lot (I like about 25%) - especially if using motor braking (back-EMF pulses can be higher than battery voltage).
