I have a feeling that the load demands and recharge rates of NiCd wouldn't be enough for the elec system. Quite why they went with LiCo rather than LiMn is beyond me. Going to try and short an LiMn one this afternoon. (Don't try this at home kiddies )
Why stop at LiMn? LiFePO4 is even more inherently safe and has lots of accumulated use experience in abusive situations. It does not have as good an energy density or internal resistance, but both are better than for NiCd.
