@Robo_Eng_13 What are the negative impacts of this, knowing that for many high school students, pushing the reset button is probably going to come before asking for help when something goes wrong?
The impact will be that the most recent history for the battery management system will be lost. This may only be a few minutes, but could be longer. The result will usually be an incorrect display of battery capacity until the next full charge/discharge cycle has occurred, but it will also impact things like charge cycle counting. The reset switch was hidden for a reason, it's a last resort solution. I understand that with the original battery firmware its use was needed far too often, however, after the October update we would hope that battery "crashing" (for want of a better term) is a thing of the past assuming the battery is still in good condition.
@roboballer Hi, can you please tell us what all the various LED signals mean (besides the obvious green bar)?
In general green is good and red not so much.
The green leds will show the capacity, if the red led displays when you push the button less than 10% remains.
A fast red flashing led can indicate one of two things. If the battery is connected to the robot and is discharging, it means critical low voltage, the battery should be charged. If the battery is being charged it means there has been a charging error, this can happen if one of the cells has become damaged or if one of the cells achieves full charge before the others. We are improving the handling of this condition in the next release, if after a few discharge/charge cycles the flashing red led does not go away when charging, the battery may have been damaged.
A slow flashing red led is extremely rare, it is another type of charging fault that would usually mean we have been charging for too long but can also be trigger by other conditions. Charging will have been terminated if this happens.
A solid red led that illuminates when powering the V5 brain when no other buttons are being pushed means that shutdown due to low voltage/capacity is imminent, usually you would have less than 10 seconds before the V5 will turn off.
All this relates to firmware in vexes 1.0.2.
