[FTC]: Using Anderson Connectors for wiring.

[Al Skierkiewicz]

Phil,
the part of the rule that triggered my response is the
o. Non-NXT power, motor control, servo, and encoder wires and their connectors may be extended, custom made, or COTS subject to the following constraints:

followed by:

s. Electrical components that are not specifically allowed by the rules (i.e. sensors, batteries, microprocessors, etc.) are not permitted. Motors, sensors, controllers, and any other electrical components may not be altered from their original state in ANY way unless specifically allowed by the Robot rules.

Emphasis mine. Since the battery is an NXT power device under par. o and an electrical component under par. s, I read this as no mods can be made to batteries. I did not check the FTC Q&A to see if there is any response there. That does not mean that APP connectors are the better choice, just that I believe the battery cannot be modified.
