Battery used

  • From all of us at Scout Motors, welcome to the Scout Community! We created this community to provide Scout vehicle owners, enthusiasts, and curiosity seekers with a place to engage in discussion, suggestions, stories, and connections. Supportive communities are sometimes hard to find, but we're determined to turn this into one.

    Additionally, Scout Motors wants to hear your feedback and speak directly to the rabid community of owners as unique as America. We'll use the Scout Community to deliver news and information on events and launch updates directly to the group. Although the start of production is anticipated in 2026, many new developments and milestones will occur in the interim. We plan to share them with you on this site and look for your feedback and suggestions.

    How will the Scout Community be run? Think of it this way: this place is your favorite local hangout. We want you to enjoy the atmosphere, talk to people who share similar interests, request and receive advice, and generally have an enjoyable time. The Scout Community should be a highlight of your day. We want you to tell stories, share photos, spread your knowledge, and tell us how Scout can deliver great products and experiences. Along the way, Scout Motors will share our journey to production with you.

    Scout is all about respect. We respect our heritage. We respect the land and outdoors. We respect each other. Every person should feel safe, included, and welcomed in the Scout Community. Being kind and courteous to the other forum members is non-negotiable. Friendly debates are welcomed and often produce great outcomes, but we don't want things to get too rowdy. Please take a moment to consider what you post, especially if you think it may insult others. We'll do our best to encourage friendly discourse and to keep the discussions flowing.

    So, welcome to the Scout Community! We encourage you to check back regularly as we plan to engage our members, share teasers, and participate in discussions. The world needs Scouts™. Let's get going.


    We are Scout Motors.

I asked Scout whether they would use these next gen batteries,


They responded

Hello! The main battery is projected to use Nickel Manganese Cobalt (NMC) chemistry, which is common in modern electric vehicles for its high energy density and performance. However, you can certainly post the suggestion on our community forum at https://community.scoutmotors.com/ (https://community.scoutmotors.com/)!
Thanks for posting their reply.

I have my doubts about the Verge motorcycle. They claim it is in production, but quick google showed that it was a limited production run (100 units). Their extended range model has a 33.3kw/h battery. Hard to guess how many of the SS bikes will be made and how quickly they will make them - but there is a big difference in scale between numbers and battery size between Verge and Scout. Oh, and the 10kw extra battery size on the extended range verge cost an extra $5k - so they have a bit more margin to play with than Scout as well.

Something will be first with a SS or semi-SS battery. But I suspect it will still be some time before new battery tech will be available for mass production at reasonable quantities and price.

In the past Scout has posted they expected NMC for the EV and LFP for the Harvester. I do not know if that has changed. I assume the thought was the smaller Harvester battery would need more C capacity and cycle life to have similar performance with it's smaller battery, while the EV would be more sensitive to battery density due to the larger battery size.

It so far out, probably another 25 years before its mass produced. Unless China is able to make it for mass production which from what I have read it's a very expensive transition of tooling for SS, and then maybe US car companies can import them and reverse engineer it.

I know that BMW is mainly focusing on Lithium-Ion Technology since SS is too expensive upfront to mass produce at scale. And that it would be too expensive for the consumer.

Watched a handful of videos on the Donut battery. One made an interesting observation. Apparently Donut made an investment in a company working with nano-materials and capacitors. Their capacitor had a lot of similarities to the battery that Donut was talking about. Charge speed and profile, non-lithium, forget if they mentioned density. Of course capacitors come with their own set of issues - those were not addressed. Even if they don't loose charge rapidly, they tend to have virtually no internal resistance and can very rapidly discharge (imagine 140kw/s arching in a fraction of a second - maybe not technically a fire or an explosion, but hotter).
