Has anyone used one of these before? I was thinking of using one with a LiPo battery pack rated at 2C. Would that be sufficient?

Looked at their website, and the following gives me pause:
"Efficiency and available output current
The available output current depends on the input and output voltages. The input current is limited to approximately 2 A, and, as shown in the graphs below, the efficiency is typically 80% to 90%. Therefore, the maximum available current will be approximately 800 mA when doubling the input voltage and approximately 400 mA when quadrupling the input voltage. At high output powers, the 20% lost in the regulator will cause substantial heating, which can limit the available output power (the regulator will automatically shut off if its internal temperature gets too high). At low output currents and high input and output voltages, the efficiency drops closer to 50%"
That leaves me with the impression that it can't provide adequate current for our applications. Someone that knows more than me may disagree.

Don't know if anyone has tried this; but it looks promising - a 10 watt max.
