hv maxx and lipos

[mwe-maxxowner]

I found an old hvmaxx ESC with the 6.5 motor in some old stuff. I'm thinking about trying it in a slash 4x4 with revo sized wheels and tires on it.

Is this ESC capable of running 4s lipos? It's already been re wired for one battery pack.

If memory serves me correctly, it will require an external lvc, right?

Any ideas how it should be geared in something like this?
