I am now running an HV system w/ my MGM and its awesome. Just bc you run 8-10S doesn't mean its automatically high power, it just depends on the amp draw, and if done properly the efficiency is huge and the system stays super cool. I can run mine WOT thru long grass non-stop for the entire pack and the whole system barely gets warm. Its so freaking cool (literally and figuratively) compared to the 8XL system I had before where I had to watch temps and worry about pushing the system too hard.
The efficiency of my system is 94-95% according to Neu's motor calc and my ET data. Compare this to my XL system that was at best 75% eff. I have an amp draw of 45A max, but way more powerful than my 8XL drawing nearly 120A on half the cell count (notice that would equate to 90A is eff were the same, that ~30A diff is wasted as heat.) Even tho my system is "only" 1300W, its actually putting out more usable power than my 1600W XL system.
On top of all that, that means better runtime, smaller batts needed, lighter weight. Instead of buying a 4s2p batt, run it 8S1P and get better results. For extreme speed I'll get a 10S1P 2100 batt, weighs less than 550g, and puts out the equiv of a 2600+W XL system. I don't think I would want to run less than 8S again.

Here is what Joe Said:
"I'll work on the Hydra HV pics gents...not sure if we have some ready or if I'll have to snap some when the pallets get back from IHobby. Those who want a 12s car version are going to have to do an AWFUL LOT of begging to get that. The Monster Max will be good for 6s and 200A...that should be good for nearly all apps...1/10 monster, 1/8th scale buggy (possibly truggy). About the only thing it wouldn't cover is 1/5th buggies like the Baja, and other crazy scratch built vehicles like I saw at IHobby this past weekend in IL....but I'm sure you guys will try it anyways. Let me know how it goes.

I love my cool running HV set up. It is amazing that the only thing I have to watch for are my diffs and shafts LOL. Like you said the efficiency is up there and everything runs cool when geared right.
