Anyone seen these yet? New lipo technology...can be charged to at least 4.27v/cell (although it is said that life span could possibly be shorter than conventional lipo at these voltages), or used at 4.2v/cell in the same manner as conventional lipo.

This stuff excites me because I'm always looking for people/companies that are willing to go off the beaten path and innovate. While the ability to charge to higher voltages doesn't really benefit sanctioned racers who are limited to 4.2v/cell, it's still interesting to see things changing. John Grzan, (who started revolectrix and was first to bring this technology to the RC market) says that we may see 4.6v/cell within a year.

Sure, classes are currently calculated to run 4.2v/cell, but that will change with the technology, just as it did when we made the jump from nickel to lithium.
