Of course, you could also get a low voltage alarm. It is a small chip that you plug the balance lead from your lipo into. it will make a loud beep when your battery gets to a predetermined voltage. Most are 6.4 volts (3.2 volts per cell). They sell them on ebay for less than $5.
other than watching for the low voltage, the XL-5 will have no issues handling a 2S Lipo.
