So the value prop are multiple things:
- you can indeed change the cells! When the industry matures, we might have a "second-life cell cycling" path where old cells are re-tested and matched so you could switch individual cells, but for now, as those "matched cells" aren't widely available we recommend you switch everything to new cells (this would cost an end-user about $50 rather than buying a new battery for $200/$300)
- our battery is also very high quality (passes all certifications, waterproof, fireproof, connected, with safety alerts)
- even if you need to change all the cells sometimes, getting back "pristine cells" rather than "damaged, welded and unwelded cells" will allow for multiple things: putting them in a second-life cycle for eg. energy storage batteries, and even better recycling (since you can get cells out of the casing, the recycling process is even more efficient)
- now the cells are perhaps 1/3rd the cost of a battery, so all things being equal, you'd rather be able to change all cells than throw in the trash the old battery
- we also have seen some batteries fail because of broken electronics, etc, which are just $30 to replace, and our battery makes it extremely simple to do so
