I agree. From what I've read, the idea is to set the cutoff such that when the battery is disconnected from any load, the voltage will rise to ~3.6-3.7v again after 15-20 minutes.

That said, I would set the cutoff to 3.2v and then run it until the ESC stops. Let the battery sit disconnected for a while, then hook it to the charger and see what the standing voltage is. If it's 3.7v or higher, maybe reduce the cutoff to 3.1v.

3.2v is a safe cutoff to extend the life of the pack, but of course the runtime will be slightly less than if you set it to say, 3.0v. I say slightly because at that point of the packs cycle, the voltage drops quite rapidly so any runtime gains would be minimal.

What is the max amp rating of the balancer? Does it actually charge through the taps, or does it charge through the main power leads and just monitor/balance through the taps? I think MetalMan mentioned somewhere that the taps are good for 2-3A max, but that's just from memory.
