Lipo Batteries (yes or no)

[codieskid]

Just been reading about Lipo batteries here: http://www.teamorion.com/Products/Batteries/Lipo

Has anyone ever used any of these, if so are they any good and what are the advantages/disadvantges. They sound pretty good but will they fit in a zx-5 and what modifications would need to be made to get them to fit?

so are they lipo, go go or a lipo, no no? (sorry that was terrible)

Cheers
