I see all kinds of red flags from looking at the promo on that website. Red flags such as "Much of the technology we are using will be revealed at a later date as we are still working on the patenting of our solution." I read that as "We haven't figured out how to build these things yet, but we hope we will eventually be able to do it, if we can get enough investment money thrown at us."
Another indication that they don't know what the heck they're doing is this claim: "This pack will use a Lithium Ion technology, not unlike the cells used in Tesla’s battery packs."
Ummm... don't tell them, but pretty much
all BEVs being made today use lithium ion batteries. That includes the Nissan Leaf and all of Tesla's cars.
I absolutely would not give this company any money, not even $1 for a reservation, unless and until I saw some reports from actual retail customers talking about how well -- or how poorly -- these packs work. And that's assuming that they really will produce a product; that this isn't yet another investment scam. Frankly, I suspect it's the latter.
Like I said: Lots of red flags there at that website.
