RANGE! At 50 Wh/kg that puts them close to equal with advanced NiCd. NiCd and NiMH have all been tried by the OEM's (manufacturer of Consumer Ev's) and determined(by them) to be lacking in range for the price.
The OEM's won't be happy until they can get a battery with a range of 400 miles and 10 minutes to recharge all at a cost of less than 3k. Of course if that should ever happen then they'll change their requirements. Stay Charged!

It seems that 25-35 puts it equal with some of the technology, and the "refueling" feature seems to give it a leg up. Although, they never mention purchase/manufacture price, so if that is too high, then it has to compete with the capacities of the more expensive batteries. I wish battery technology advancements moved ahead at the same pace that computer technology does, instead of this "wait ten years for something to happen" pace. Lonnie
