Lipo for e-maxx

[RC-Monster Mike]

I have not run the polyquest (lipoomaxx has much more lipo experience than I do, so I trust his judgement on these). They do seem to be a nice option. I use the Kokams because they deliver the most power per ounce (amp draw capabilities). I only race for 5 minutes, so runtime is not my main concern. On my xl2400/5s Kokam setup, I am sure I could easily finish a 10 minute main, though. With 4400s, I would imagine 15 or so minutes would be pretty reasonable to achieve, depending on the track, the truck and the driver! 8800mah and 18.5 volts on a low Kv motor would run for quite a while, but you would need to keep the motor temps in check more and more as you increase runtime.
