I belive the mm can be set with a castle link to custom voltage cutoff and set for a 4s lipo???
I would look at a battery that will provied a little more in the amp department. They have a 5200 24c that would be great! Or a 8000 12c (both are pretty inexpensive)
i was looking at the 2s 8000mah 12c but isint 12c too small? -Wes
