If it's a 7.2v pack, those are 3.6v nominal cells, which is obviously a little lower than the typical lipo 3.7v.

There are a couple ways you could charge that, depending on your charger's capabilities:

1: Set the CC/CV threshold to a lower value, something like 4.0 or 4.1v/cell. The charger must support a settable threshold, read the manual to see if it does. Or, there may be a "storage charge" setting where this value is settable.

2: Charge it on a 2s lipo profile but watch the voltage. When it gets to 4.0-4.1v/cell, manually lower the charge rate to keep it no higher than that. Your charger must support on-the-fly current adjustments; most don't. FYI: I don't mean stop the charge, set the current lower, restart, etc; I mean adjust the current during charge.
