The genius of all this is that as battery tech improves the existing plane just gets better and better. When you're looking at your replacement pack 5-10 years down the road you'll automatically benefit from all the improvements and your new pack will either be cheaper, or it'll fly longer, or it'll be lighter. Maybe all three. Certainly never saw 100LL get cheaper, better, and lighter!


Well, ten years ago the FES folks came out with with their Gen 1
batteries featuring 2.1 kWhr of capacity. Now we're up to Gen 2,
featuring a walloping 2.1 kWhr. See how much improvement there's been?
They did manage to take the metal filings out of the packs, so yeah I
guess they did get a little lighter.

Wonder if Nadler has ripped the batteries out of his 15 year old wings
and put in super cells to make an Antares Turbo? I'm guessing not.

So do people buying a self launcher only want to do a 1K' launch? The
guy in Connecticut thought he'd dip into the "excess capacity" somebody
was talking about, and squeak back to the airport at rooftop level.
Unfortunately he found himself below rooftop level in no time flat.

They're onto GEN3 now:
The GEN3 53Ah / 5.5kWh packs have 32% more energy in a package 13% larger.
The GEN3 70Ah / 7.7kWh packs have 85% more energy in a package 25% larger.
