Concerning the NAVIGA mono, hydro and eco classes, we will probably see something very similar to the agreement. Naviga actually just started to think about it, we are doing tests during the year. The earliest date for LiPo in NAVIGA would be 2009 though, the Worlds 2008 will be NiMH only.

Every organization is in trouble once the technology changes rapidly. The key word is RAPIDLY. The switch from NiMH to LiPo is bigger than it was from lead acid to NiCd 35 years ago and especially bigger than from NiCd to NiMH.

And right now we have trouble from 2 sides:

First, the existing battery technology is pushed to a level that the cells last only very short time. The latest chineses NiMH cells are very powerfull, but whimps concerning life time. That's what makes it hard to stick to this technology without loosing people because of the high costs for replacing batteries.

Second, the LiPo technology got better very quickly and comparing similar capacity or watt hours now, it is more powerfull (peak power) at half the weight - and 2-3 times the initial costs. BUT, it's said to have much higher life span.

So from the 2 battery solutions, even though LiPo is rather new, LiPo looks much better. But as pointed out, it means quite a big change, the limits are not well known yet and - most important - it's more dangerous if used in the wrong way. So finding the right rules is'nt an easy task.
