Question for those of you who own one.

When balancing a pack with a smaller "3 hole" balancing connector (found on the 7.4v packs), how and where do you plug it in? The balancing adapter which plugs into the charger doesn't have the "3 hole" spot; all the plug ins are larger than that. I have the manual printed out and it doesn't seem to address this issue.

Hopefully I'm being clear enough. Thanks for any insight.
