The the original Ezee Nimh battery weighed 5.5kg, the Phylon Lithium about 4.5kg but the quoted 3.3kg refers to the new Sanyo lithium now supplied by Ezee using the same cells (but more of them) as the Panasonic unit.
The motor is the new motor designed and manufactured by Ezee themselves, first seen in the Torq Trekking and now used in the Forza as well. It certainly is nothing like that previously used in the Sprint or the 8fun motor used in the original Torq although I expect in time it will be used in the entire range.
As for the 3.2kg controller it must be a miss-print, perhaps the decimal point in the wrong place. It is the usual Ezee controller which may weigh 0.32kg at a push but I doubt it's even that heavy.
I hope that clarifies things Leonardo.
