Our team is finding the battery life of the 7.2v batteries has gotten shorter to the point where we can run the robot for 3-4 minutes, and then the cortex battery light begins blinking yellow.
Is this normal? FYI, on our gripper-style 'bot we use four 2-wire 323 motors geared for high speed, four 3-wire motors for the arms, and two motors for the claws/hands.
Suggestions as to how we can re-program the battery for a longer use?
What difference, if any, does it make to battery life to charge the battery under Safe mode rather than Fast mode?
