: : We had a similar problem when first trying out our drive train, but after altering the code in the program, seemed to correct this error. It is definately way too sensitive, though I wonder at your voltage level. What is the reading of power when your light kicks on?

:
: We have reduced the trigger voltage to 8 volts, and it still comes on (blinks, not solid) most of the time. We know it's a false, as it occurs even with a fresh battery, and we have run well over an hour with the light one.

: We've got a Hobbes meter on the machine (running hour meter), and have over 24 hours of run time, and the light just doesn't mean anything.

The Low Battery light seems to trigger if a temporary current draw pulls the voltage under the trigger value, and won't reset until you reset the RC using the button on the RC. As for customizing the Low Battery light, unfortunately, you can't control it directly, but if you really wanted to, you could retrieve the battery voltage in your SERIN command and do the necessary number crunching for a time delay, using one of the robot feedback lights as your actual Low Battery Indicator. Just a thought...
