Re: Using Second battery to Charge Tanks

As long as the "practice" battery is connected to the robot's electrical system via the red Anderson connector, and the compressor is connected to a Spike relay on the robot, then yes, you can use the practice battery to charge the air tanks and then swap in a fresh "match" battery before heading to the field.

If you powered the compressor DIRECTLY from the practice battery, bypassing the robot's control system entirely, that would not be permitted.

I have seen one post on the Q&A on this topic:



Here is R69 and the Blue Box:




So, is it legal?
I read this as one compressor and one battery mounted on your robot. Therefore, it would be illegal to change the battery after the tanks have been charged.

Am I reading the rule correctly?
