Question to Quark owners! Cut-off only 3.0V

Hi Guys,

My brushless LST is almost finished, I'm going to run a Plettenberg Bigmaxximum and a Quark Airmaster 125B on a Flightmax 5000mAh 30C 5S LiPo. But on my Quark the cut-off voltage can't be set higher than 3.0V. But from what I read here on the forum is that if you're running high amps set-ups you should set the LVC higher than 3.0V, 3,2V or something like that.
Well, what should I do? On my Quark I can set LVC from 2.4V (I thought) up to 3.0V. I always had it set on 3.0V for in my Rustler VXL on 3S, and it always worked fine, but that car doesn't pull such high amps currents.

Any advise what to do? Or how to set the LVC higher than 3.0V on the Quark? (Maybe I misread something?)

Thanks,

Patrick
