I can address people's questions about this product, I'm the founder of Fenix, we've had a ton of questions about how our solution works and have updated our FAQ to address them. But that doesn't cover everything, so let me know if there's something else you'd like to know.

But to address a couple from what I see above: We knew we were taking a bit of a risk announcing this early with fewer details than we intended. Our roadmap had us announcing this coming spring when we would have quite a bit more to share. But with Nissan raising their pricing, we had people who knew about us asking that we announce sooner so people would know there are options coming. This is also why we're including such a deep discount (90%) on the reservation/installation cost right now. The installation cost of $1,500 mostly goes towards freight, batteries are heavy.

But for anyone willing to commit this early, we'll eat the majority of their install cost as a thank you for their willingness to sign up now. And of course, as we get closer to spring, if the details don't look good to you, the deposit is refundable.
As for the monthly pricing, the Leaf is just the first application of our solution, and we'll be building our service to scale to other solutions. So pricing will actually be on a capacity/storage basis and will be a few dollars per month per kWh. We're designing as much flexibility into our physical and service solutions to give customers as much flexibility as they want. And sure you can lease a Zoe pack, but will that pack improve over time? Ours will.
We're in this not just to help Leaf, but to completely change EV, we think that this common design of a monolithic, expensive battery that can only be replaced by the OEM manufacturer is an obstacle to greater adoption. It's time that batteries were made serviceable, and provide more flexibility for the owners, and we're going to show the world how that's done for both the Leaf, and in a "Halo" product in a Corvette C5 conversion.
