With the reinforced mount LiPo rule I would have thought it would be better to have a rule where the mount is designed to still hold the LiPo in the event of a fire (so not tape or Velcro) so it cant fall out like during movement of the robot to a safer area, or fall to other areas with in the robot (like against flammable surfaces, like plastic, or expensive equipment).

I think having a secure mount to stop movement of the batter would make the situation a lot easier to deal with, as you know the battery wont fall out, fall against the base and make a molten, fiery, plastic mess which seeps into the floor.

also a port, or entrance for a fire extinguisher, for engulfing the LiPo in Co2, could also be useful, could be clearly marked or something?

I think that an incident is inevitable, no amount of armour and fuses could stop this happening eventually, so its better to just reduce the danger, damage, and make it easier to handle?
