Seems like it will be. But Tesla has been really cagey about actually doing battery swaps. I hope they get more free with this in the future. For instance, what if I want to swap in a 90kWh pack into my 75kWh car that someone sold due to buying a 100kWh pack? I'd then want my 75kWh pack to go someplace: either I put it in a conversion kit to work as a time shift for my solar panels at home, or I send it back to Tesla for THEM to re-integrate those batteries into a time shift fixed battery storage product. I'd like to see much more liquidity in this type of activity. So far, it's been pretty damn lockstep. Part of the problem is that the fixed storage business is pretty young, and supply constrained, and the cars are supply constrained too. You'd think this would allow shifting used batteries to the supply-constrained marketplaces as long as someone is interested in buying a new upgrade, but it is SO supply constrained that Tesla doesn't even NEED to service these upgrades, since all they have to do is force you to trade up a whole new car or fixed storage, and just not worry about it AT ALL -- it's a seller's market right now.
