Slash 4x4 with HV-Maxx
 

So I'm considering picking up a slash 4x4 roller off of Ebay. I have heard that it is possible to run the HV Max 4.5 off of a lower cell count. What would I have to do to my HV Maxx so it could take this lower cell count and how much modification is needed to drop it into the Slash 4x4?

Just to wire it for a single pack which novak shows you how to do and run it on 2s...

Worth adding the heatsink / fan as it still runs a wee bit hot...
