2s lipo on MMM combo?

[Klausen]

I got a son who is 3 years old, and last year he drove my Summit most of the summer in the low gear. Now the weather is nearly ok to drive again here in Denmark, but the Summit is sold.

So my question is, will the MMM combo work properly on 2s lipo, if I set it to 20% speed in castle link in my Losi Aftershock?
