Those of you who wants larger capacity batteries may want to take a look at this graph. I am finding that the 120mAh cells that comes with the v911 has really good run time. So I did some discharge test @1A for you to see.
All the cells have at least 5 cycles through them to ensure they are woken up from storage. Then I discharge each cell a couple of times to ensure the results are consistent between runs. Here are the results.
As you can see, each of the v911 batteries gives the Hyperion 160 a run for the money. You can also see where each of the Turnigy 160mAh lies, as well as the two NanoTech 160mAh I had on hand.
It's interesting to note that despite the v911 being a 120mAh, I am putting back about 140-144mAh. It's besting the Turnigy and NanoTech in voltage and capacity. Flight time wise, I can get almost 6mins, bringing it down to about 3.7v. And I can still hover. While the each of the Turnigy 160 forces me to land at 5mins exactly.
We'll see how long the v911 last. But I am very quite please with the result I am seeing. In fact, for the size and weight...it's technically better than the Hyperion battery.
Another thing that is interesting. Of the two v911 batteries that came in the box, battery 1 was performing more like the Turnigy 160. After the 8th cycle or so, it woke up and started performing like it's brethren.
The take away lesson is this. I rather have lower capacity cells that are of quality and provides good voltage throughout the discharge curve versus high capacity cells that falls short and weighs down my heli.
