I'd be concerned about buying a $1,300 battery-powered skateboard without the ability to replace the battery.
I'm not exactly sure how much it costs them to produce the battery, but it looks like single cells of similar LiFePO4 batteries are about $20/ea. With 12 of them, that's $240. Add maybe $50 for the BMS and $10 for the enclosure, and the whole battery pack is maybe $300?
It'd be a shame to have to replace an entire $1,300 skateboard after a few years when your battery capacity is reduced, when all you needed was a $300 battery pack. Hopefully "non-swappable" means something besides "non-replaceable".
- kogir 13y agoI can't speak for them, but I'm one of the beta testers and am under the impression you'll be able to send in the board for battery replacement when it finally dies. It's just not user serviceable at all.
- skdoo 13y agoYes, we mean "non-user-replaceable". It is easily swappable at our facility.
- baddox 13y agoJust like Macbooks. Definitely not a deal breaker.

- hengheng 13y agoExcept today's Macbooks will be outdated and superseded in 5-10 years, whereas a skateboard won't.
- atourgates 13y agoWhat data have you found in terms of long-term performance/degradation on your battery packs?
- skdoo 13y agoWe haven't finished our own tests, but the cell manufacturer's specs have been accurate so far and they promise very high cycle life.
- karmicthreat 13y agoWhat manufacturer did you use for cells?
- reportingsjr 13y agoThey are using A123 (or rather B456 now) cells. You can tell this pretty easily by doing a google image search for "a123 cylindrical cells" and comparing the pictures in the blog post.
- hengheng 13y agoAlright, so what life time can one expect as a customer? And economically speaking, how expensive will a battery swap be? The whole reason I'm asking is this 20 year old skateboard I have down the hallway, which is working flawlessly with every single component easily swappable :-/
- netcan 13y agoAlso, a cool thing about skateboard is how components (board, grip, truck wheels) get swapped out as the wear out. Each component gets to live out its entire useful life (and then sometimes gets a second life as a spare). The transition between one skateboard and another can be completely gradual. One piece at a time until nothing is left. User serviceable is a part of the culture. It would be nice if that could survive.
