The way i read the thread i posted above is that safety is a concernbut they are worried about the difference in overall voltage.

In NIMH's they are alway losing voltage to maintain power and eventually you will see it slow because they are drained, Where LIPO's maintain voltage to a point where the amps start to fade and voltage has to drop to get more amps.The chemestry is different and so is the power so its not fair for those who have NIMH because they are at a disadvantage. I don't see the size issue they have as a reason because the NIMH cells don't fit the rules for dimentions either. 3300,3600,3800,and 4000+cells don't fit where the 1700 and 2400's fit and were the basis for the dimention rule. I think battery manufacturers are responsible for the rule against Lipo's, they would have to spend money on new equipment to match and zap (if possible) a new set of battery packs.
