I spoke to Anker this morning about using a one of their portable batteries that us a Intellicharge technology. The state it will handle a RaspberryPi and keep the voltage within acceptable levels. The was a "however" - if the RaspberryPi switches to a low power state, the battery may shut off because the battery thinks it no longer needs power. So question - Does anyone know if you are using a RaspberryPi/DVMega combo - does the Pi every go into the low power state? Thanks in advance.
No, there's no such thing. Closest thing to a "low power state" would be after the OS has shut down, at which point if you could make the power brick shut off automatically it'd be a feature instead of a bug. :-) But the Pi/dvMega with DStar Commander running will draw around 250-300mA...more if you're using a WiFi dongle for internet connectivity.

After extensive research on this subject, I've come to the conclusion that the power level of the Pi has very little fluctuation in it's power requirements. Especially when running a DVMega, as the radio is always running. I did a usage test and found the battery lasted 25 hours and still had .25 of it's usable power left. No glitches, no problem.
