Yes they are still available
The voltage might be too low. It will go pretty fast into direct drive mode but since the Vf of the XM-L are pretty low compared to the Seoul P7 you may stay in full regulation until the batteries are empty.
Last time I measured a Vf of 9.8V with 3 XM-L, should be low enough I think.
