Anyone using a 1515 2Y???

BTW, I will try to run on 8S this setup. Just seeing if anyone else may have given this setup a shot.

Yes. Awesome and won't go back to 6S.

So far, I'm only hitting 60A spikes and depending on the battery I use, I get up to 45 minutes. My truggy (Mugen MBX5T with a Mr. C conversion) is very light and only geared for 34mph. I use 2 4S 3200-3700mAh packs.

Longer runtimes as in what? You want more running time between battery swaps? If so, you aren't going to, running higher voltage does not really bring longer runtimes, it does bring lower temps though.

Compared to a 4S or a 6S set up (I tested both btw), the 8S set up of mine has only been asking for 60-80A (Depending where I run) spikes and the AVG. is anywhere from 5-10A. The latest video where I used the new 10S ESC on grass, I saw the most an 80A spike and an avg. of only 8A.

Sorry if the picture is too big.

Forgot to add that a smooth driving style will play a big part of how much current you use and this will help in going further on one charge.

Do you have real world experience to justify your statement?

Just looking at your statement logicaly, it doesn't make sense. If a higher voltage system produces less heat then this simple fact alone is proof that higher voltage would provide longer run times. The lower voltage system's wasted energy, from heat, will reduce its run time. The difference of the two system's runtime may be small but it exists none the less.

My real world experience has been the higher the voltage, the longer the runtime. The difference in runtime isn't that much but is measurable.

I think he meant that the increase in runtime isn't a lot.

The biggest gain will come from driving style and how much gearing one needs.

I agree, you will gain from proper setup.
The appropriate voltage/motor kv/gearing does wonders.
