If the voltage of a lipo cell runs below 2.5v nothing will happen to it.
It would be in everyones best interest if you make sure you know what you are talking about before posting. This just leads to misinformation being spread and newer users have a hard time differentiating fact from nonsense. Lithium polymer cells (and ALL forms of rechargeable batteries) can be damaged if individual cell voltage drops below a certain point. That particular threshold varies based on the configuration and kind of cell in question, so the same rules that you apply to sealed lead acid batteries cannot be applied to Nickel metal hydride batteries or lithium polymer batteries. All rechargeable batteries can be damaged by overcharging or overdishcharging. In the case of lipos, people familiar with the technology seem to agree that the load should be removed when the cell potential drops below 3 volts. You may or may not be able to revive a deeply discharged lipo, but regardless you are shortening the life of the battery if you do not follow accepted charging and discharging guidelines.

Good post!
I have been heavily into Park Flyers for several years and have been using LiPO's for about 3 years now. At the present time, the lower limit for every LiPO cell IS 3.0V. If you discharge below that, kiss it goodbye. It is very important to have a 3.0V BEC when running any LiPO to protect your investment. On the flip side, it is also important to have a cell balancer when charging a LiPO to ensure that all cells in the pack are equal. LiPOs are rated at 3.7V per cell. a 2S LiPO pack is 7.4V, a 3S LiPO pack is 11.1V, and so on. No cell in these packs should be allowed to discharge below 3.0V or you can kiss the pack goodbye.
It is important to get and give correct information to help new folks in the hobby. Bad information can cause someone new frustration, money, injury, and in extreme cases, disaster. If you know what you're talking about, please share. If you don't know what you're talking about, please keep quiet until you do. If you're unsure, make sure that point is known.
I'm not going to get into the discussion of whether nitro or electric is "better". I own and enjoy both for differing reasons. I suspect we all have our preferences and that should not necessarily impact another's preference, nor should any attempt be made to force your opinion on someone else.
