I think if your main battery drops below 7.2 volts at any time, it is probably not fully charged. However, I could be wrong...
Eldarion,

Try sourcing 533 amps from the battery at the same time you are using it to power the camera and tell me that you have no problems...

Using the 4 "small" CIM motors for a drive is probably the most popular drive configuration this year...

533 amps is 4 small CIM motors in a stall condition (133A each). Not to mention 2 bike motors, 2 FP motors, et cetera...

I predict that many robots will peak at over 800A during the competition. As Dave Lavery said at the kickoff, there will be "meltdowns"...

JMHO,

Mike

Edit: Look at this data.
