I think I understand what the documentation is trying to say, but this can be misleading. The voltage should be left out of the battery "section" and perhaps mention that the system must be powered by the DC jack. Because 2s batteries are 7.4v nominal, and fully charged 2s batteries are 8.4v You see what I'm getting at ? When you include the DC jack voltage into the battery spec section, you're confusing the issue, and almost making the documentation contradictory. e.g. it almost makes it seem like a 3s, or maybe even a 4s pack would work. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
