I'm strongly thinking of purchasing an Ego mower but I'd like to know what type of lithium chemistry you use before I take the plunge. 

Do they use lithium iron phosphate, lithium NMC, lithium NCA or lithium manganese oxide? Perhaps you could even tell me the manufacturer of the cells. Even the nationality of the company would be great. That would be really helpful. 

Kind Regards,

It shouldn't be LiFePo4 though, since they use 14 cells with a voltage of around 4V each . . . the phosphate cells have a lower nominal voltage than that.  I also wonder this.  There's a video on youtube from SuperSpeeder (https://www.youtube.com/watch?v=lRdBS9oFUXc) who takes them apart and compares them to a (MUCH) lesser pack from another competitor.  The EGO pack is leaps and bounds better engineered, but the individual cells were shrink wrapped so I couldn't get a gander at which 18650 cells were exactly being used.  The other brand was using some LG cells, but I couldn't tell if they were INR, IMR, or ICR - I'm assuming they wouldn't be Cobalt, because of the high C/Rate charging and discharging, but I could be wrong.  

I'd love to know not only the chemistry of these cells, but also the specific brand of the cells.  It appears the newer 2.5 Ah and 5.0 Ah use the same AMOUNT of cells, being the same physical dimensions and weight as the older 2.0 Ah and 4.0 Ah packs, so did they just upgrade the cells to a higher capacity, or did they go with a different brand of 18650's altogether??
