If you make the argument that lead acid batteries are hazardous material and shouldn't be used on robots that may take hard hits, then we shouldn't be allowed to use them at all. It's definitely against FIRST's safety principles to say "yeah it's hazardous and unsafe, but a
little bit is OK, just this once."
I'd buy it if the mounting solution was considered unsafe, but that's not related to how many batteries are on the robot.
Given that it's an ambiguity in the rules (It COULD be legal...but it also could not be, depending on how you read it), I think it's perfectly fair for the LRI to make his interpretation that extra batteries of the same kind as the main robot battery are illegal. What bothers me is that it seems that 1902 was given a signoff/pass by an inspector (maybe not the LRI) that it was OK. Lacking a formal re-inspection process and documentation, that should qualify as a passed inspection. If the LRI disagrees and wants to make them change it after it is brought up, that is also fine. But a T6 shouldn't be given to a robot that had passed inspection, regardless of if the LRI thinks it should or shouldn't have.
In my opinion, the entire thing gets hung up on what is or is not an "inspection", what process the teams and inspectors are supposed to go through to get re-inspected, and ensuring that both the team and the inspectors involved are on the same page as to what is being agreed upon.
