I tried this on 10s for the first time today. I again geared for 50mph (16t pinion) so that I could compare performance and temps to my 8s setup. Unfortunately my run was cut short by a broken pinion

I drove it hard again and used up 2.03Ah in just over 5 minutes. Comparing temps to my last logged run, it appears that both the esc and motor are running cooler.

Temps at end of (shortened) run:
ambient: 76F
esc: 105F external 118F internal
motor: 136F
batteries: 108F

The batteries I used for this were Turnigy 3600mAh 30c - and they didn't seem to have as much punch as the 40c batteries I normally use.

Here's the voltage and current plot:

Max current: 92.5A
Max power: 3147 W

What this tells me is that 10s is better, but I should stick with batteries with a higher current rating (although the 3600mAh 30c's should easily be capable of the currents I logged today). I'm looking at buying some new packs since my 40C 5000mAh packs are losing some capacity, and this shows me that I want to plan on running this on 10s in the future.
