    For batteries, I understand that you don’t want to go out on limb, at least initially. So cylindrical cells, probably NCM chemistry, 400v … all standard stuff, and the key thing you’re thinking about is integration. I get it, but the pushevs website has these things to think about for the future:

    800-volt systems: more efficient, lighter motors vs. 400v

    Silicon anodes: silicon/graphite is here now, but higher % silicon is coming

    Cobalt-free batteries: switch from NCM to LFP, you’ll lose some energy density, but gain in safety and cost, simpler management, and no conflict minerals

    CTP battery packs: Check out BYD’s blade batteries, works well with LFP chemistry

    Solar roofs: Aptera is already there!

    V2G and V2L: vehicle-to-whatever is coming

    Aerodynamic improvements: Aptera is already there!

    Wireless charging: well, someday

    30% of price up to $7500, so no, you won’t make a profit on it 🙂

    I believe the minimum battery size for 2 and 3 wheeled vehicles is only 2.5 kWh, so Aptera would qualify pretty easily 🙂

    Tesla is selling Model 3s with LFP batteries in China and Europe, and now possibly in the U.S. I’ve seen a few of the articles about charging and cold weather range, and while I don’t doubt that it’s true, this may also just be Tesla working through a few kinks ie as usual, their customers are the beta testers.

    I think LFP is the future for EV batteries: cheaper, safer, no supply constraints (other than lithium), and no conflict metals. Other changes are coming, such as silicon anodes, that will raise the Wh/kg numbers.

    All that said, I’ll be shocked if Aptera has LFP batteries right out of the gate. They have enough on their plate already.
