As to modifying the SB50/120 connectors, the intent of R66 is to prevent teams from modifying electrical items in such a way that would cause a safety issue. Removing anything from a high current electrical connector may affect the safe use of such an item. R9 is also a little more pertinent to this question. The SB connectors are tested by UL for specified current and voltage without parts removed.

And I'm sure they are tested without being painted or modified on the external surfaces of the connector as well. What's to prevent a team from wrapping a 1 1/2 inches of Viton around the connectors and 4 inches down the wire? Is that legal? My thought process tells me it is acting as insulting device and not allowing heat to be dissipated and possibly causing a meltdown.

The intent of R66 is to prevent the intentional modification of electrical components to maintain some reasonable level of safety. I am all for innovation, but there are some guidelines and rules we all need to stay within.

Plus, if you make it to the finals and you need to borrow a 'spare parts' battery, it will have a SB50. You won't be able to connect.

"The SB50 connector series is keyed by color."

It will be either a black or gray connector and it won't fit the blue one. This would be the biggest reason to not use the blue connector.

The color keyed SB50's is a nice feature if you know you'll never need to mate with a different color. We did a project with them, color coded cause it was cool and then got burned when we couldn't swap around. Decided to make "color adapters" and then decided to go black/gray all around with a strip of colored tape on the connector and cable.
