Re: BatteryBeak: Utility of making internal resistance and state of charge measuremen
Win,
The more than one match rule is hard to beat. If you go through several of your batteries and each dies towards the end of 2.5 minutes in normal driving, you are too inefficient. If the battery dies before the end of the match (exhibited by robot drive "stutter", Crio reboot and/or loss of comms) you are severely shortening the life of your batteries. I do not have any hard data on this but my gut (observation and anecdotal reports) tells me it is likley reducing by a third to a half the lifespan of a typical battery.
