READY 2 BUY....Need opinions please....

Pushing the mm with 16 cells is something i would not do.

i have got a Neu and a Lehner, and the Lehner is topnotch stuff. (as is the Neu) since the Lehner is a 2 pole it's easier to be controlled than the Neu for the Mamba Maxx.

If you are planning on running 14-16 cells the 9XL would be a good choice. My 8XL gets relative hot on 16 cells. Doable though, but cooler is nicer IMO.

Perhaps you are better of with getting an MGM16016 controller? or a 9920 with an LVC.

I can highly recommend the MGM, I have been running it with 5s on a 7xl with no problems at all. The built in voltage cutoff works well too.
