I was searching about this a few days ago... I found a big discussion thread about how in the past, teams have melted the Anderson quick-disconnects, and so, they switched to different ones (
Anderson's product line).
My opinion on this: given the 'spirit-of-the-rule' philosophy introduced this year, I believe any quick-disconnect will be okay. However, as it was pointed out, if your team does choose to go for a different type, borrowing batteries will be a bit of a hassle.
