The Nimh I saw explode happened during charging (but I think as a result of a cell not being properly discharged as a result of a failure of a discharger). It was pretty scary. People found pieces 20 feet away. Luckly the only damage was to people's ear drums.
I agree there are lots of Nimhs available but in practice one company has 80% of the market in the US (as far as racers go). There will be more then Orion selling safe lipos. I think the point people are trying to make is that for now only approve safe lipos and unfortunately to date only 1 company is doing that.
I wouldnt mind seeing a Team Br00d lipo cells. Does anyone know if Kokam's relationship with Orion is exclusive?
