Is the overall query based on, "why all the hype over hv?" when your lv setups work fine?
More so how much is hype, so I was shooting for proof of a real world difference, and at what point does it really start to help. I'm a firm believer in once your wattage needs gets to a certain point then Higher voltage is the way to go. 8-12s in a Baja, the way to go, 6s in a Rustler running 40mph, probably not going to matter over a 3s setup. In my Rustler, MMP 3800, temps are roughly the same on 2 or 3s, the system could care less. I know that's not a big jump, and maybe the kv of the motor must be changed for it to be accurate, but a 50% increase in voltage should give some notceable result, IMO. Here's an example
25/84 on 2s got me
speed= 45.8
Motor= 131
esc=112
ambient = 86


on 3s
Speed = 48.6
motor= 135
ESC= 115
Ambient = 86

Once you average the power used, the wattage was actually pretty close in the 2 setups.

I would love to see some examples like that comparing a true HV setup, if anyone has them.


This is a battery testing place, currently in the works, but he lists some wire and connector resistance specs, http://www.rclipotesting.com/Performance_Tips.php
