Quark UBEC for my Neu 1515 1.5y/s brushless system ; 5A or 6A? which way should I go?

Right that's the one.
I find the handheld device handy.
But I am not sure it is good for a big truck like E-maxx 16.8V because the manual specifically states that it is for 1/10 cars and Quark won't be responsible for any problems that occur by using bigger cars.
