Your issue is with the word "may", right? As in "[w]hen mounted on the robot, the backup battery may be charged" with the IFI device, vs. "[w]hen off the robot, the battery is to be charged" with the supplied charger. This is definitely one for the Q&A, because the intent of the rule-writer is non-obvious. Highlight (very explicitly) their choice of wording, so that the Q&A moderators don't give you a boilerplate RTFM response. In terms of posting to the Q&A forum, your team's main contact should have received login information by e-mail; ask them for the password to the account FRC135, or have them post on your behalf. If your main contact is not available, or has lost the information, ask here for another team to post the question for you.

Incidentally, here's the charger circuit from IFI (which you assemble).
