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.
