Ex got M3 in the divorce, waiting for EU Model Y!
Because CPUs are an item with high cachet, brand value, unique intellectual material in every single design, etc.
And batteries, even particularly good designs of battery, are a commodity. They're much more comparable to RAM than to CPUs. The price competition in the market is much harsher; people will desert you if the competition is 10 cents cheaper. Tesla may well have the lowest production costs and best margins in the battery business, but it's not going to have the same character as the CPU business... or the luxury car business, for that matter.
Respectfully disagree, for the following reasons:
1. Tesla Energy won't sell battery cells but stationary storage solutions. Complete solutions are levels higher in the complexity hierarchy and will give room for much better margins.
2. Customers can't go to the competition of there isn't a lot of competition.
3. And even if they're will be more and more competition they won't have the first mover advantage and economics (low cost) that Tesla will have.
All in all I wouldn't be surprised if they can achieve over 30% gross margin for many many years on Tesla Energy products. In fact for the first few years it might be much higher. Recent retail pricing they have for PowerPacks certainly suggests this.
