Shawn had posted in a CC thread back in early Aug when I was first looking at using a MMax in my ERevo, that the MMax could run 14 cells but you would have to disable the BEC. This was in response to someone that wanted to run 14 on the 4600 IIRC. Shawn had posted that was ok, but that exceeded the specs (rated upto 12) and wouldn't be necc covered. (Actually it was this post and the 7700 specs (~700W on 6 cells => 100A ) that got me thinking it would work..)

If this has changed since that is news to me. Now the ? is, if you did it, blew it up, but didn't tell them, would they know?:032: :P Prolly not..



As far as the XL goes, you're right it doesn't really matter. However I could imagine somebody saying to a company's CS "you know that Mamba ESC you designed to go into 3lb T4's and sedans? Well I hooked it upto a 1500W 540XL motor, put it in a 12lb MT, ran 14+ cells on it, and blew it up. Will you replace it?" I could see that company saying "you exceeded the specs and recc's and it won't be covered." I've heard CC's CS is really great and generally they seem good guys, but I have not had the misfortune to have to test it, so take it for what its worth.

It's out of spec, and not warranted, but yes - with the BEC disabled you can run 14cells. Just watch the overall rpm of the motor there (voltage x Kv).

But will 4s void the warranty? 4s is the same as 12 cells voltage-wise, and they even have a voltage cutoff for 4s listed in the manual. 14 cells is more like 4.5s. I know it can run 4s, but just curious about the warranty. If so, then I think I'll be using the MM in my 1/8 buggy instead of using the Quark or waiting until just under eternity for the Monster Max. I think as long as the user doesn't go higher than 4s and keeps the amperage at or under 100A, the warranty should hold.
