7.4v LiPo for receiver pack

Anyone use a 2s LiPo as a receiver pack ? I have a 2000mAh TP that I would like to use in my e-Revo for this purpose. I know the voltage is a bit high though. Do you think the servo's can take it ? There are a few voltage regulators around for this purpose, but they cost about as much as your usual BEC, so what what would be the benefit over just using a UBEC, if any ?
