9小时的持续飞行是美洲狮标准电池工作时间的3倍。

The nine-hour flight duration more than triples the duration of Puma's standard battery-only operation.

不幸的是，在百分之七八十的电池工作时间内，其输出电压都分布在电池额定电压附近。

For this reason, DC-DC converters will not work in best condition at battery rated output voltage.

然而，目前尚没有通用的方法对CPU频率和电池之间的关系进行深入研究，这导致动态调压算法不能最大限度地延长电池工作时间。

Unfortunately, there is still no universal way to analyze the influence of CPU frequency upon battery, and known DVS algorithms are not flawless.
