Can i use a 72v controller with 48v battery?

[rg12]

Is it possible if the LVC is cancelled or set very low or is there more to that then it looks?

how do you cancel the LVC?

Theoretically speaking, I mean lowering it as much as possible (some are programmable).

Yes, having just answered the question myself for my Ross build, where I'm putting an Infineon 12fet 4110 controller on the upgraded MAC 10T, parts from EM3ev (see here). Cell_man cautioned that putting a 72V battery on would be "extreme" and that he wouldn't warranty the motor. I'll be using a 48V battery and he said that'd be OK. So why the better controller you ask? Because I'll also have the MXUS 3000W motor running with a 72V battery and need the better controller for that set up.
