@InkySchwartz @bikenite Sort of? I think the DRM/IP that might be attached to batteries might be awful like printer cartridges. But I guess inside, there isn't a giant difference between cells.
@ascentale @InkySchwartz @bikenite A3 Speaking with the misplaced confidence of someone whose made a few DIY Li-ion batteries and watched a few YouTube videos on making e-bike batteries... unless there's some proprietary nonsense going on, an e-bike battery will be 12S3P or 4P circuit with a BMS (battery management system). So if the IC is still good one could, in theory, refurbish an e-bike battery for the cost of the cells and some solder.
@ai6yr A2 follow-up: Subscription based EV batteries including GPS-enforced geographic restrictions based on where the batteries can be serviced is one of the reasons I dislike EVs from Renault and probably all Stellantis brands (at least Citroën). I hope that any e-bike company who tries that will go down immediately due to a lack of customers willing to buy such crap.
@ascentale @InkySchwartz @bikenite A3. I think I worry a lot more about batteries and other parts becoming non-replaceable since cycle manufacture became more corporatized and less regulated. So while that affects batteries, that also affects other things.
But Ebike Marketplace really opens some options up, I think...well, if it weren't for tariffs. https://ebikemarketplace.com/
I do wish I weren't disabled so I could only need an acoustic bike. #BikeNite
@ascentale @InkySchwartz @bikenite That being said, there's also a reason why I own a $1200 ebike with a pretty generic Chinese motor and controller, and not a $7000 ebike with a proprietary Bosch or Yamaha system.
If my #ebike becomes effectively #ewaste, it's a lot less of a loss to me. I am one month shy of 3 years riding this bike, have not really noticed any battery degradation, yet, but I ride infrequently and for short distances, mostly.
@ascentale But the actual battery cells in virtually all ebikes are standard 16850 or 21700 Li-ion cells that are made by the millions every month in factories all over Asia.
So long as the charging circuitry remains intact, the cells themselves can be desoldered and replaced; however, doing so must be done in complete sets, or there is a high risk of catastrophic failure, fire, and even explosion.
@ascentale @InkySchwartz @bikenite A3 No, not when there are so many EVs around that you can ... borrow the li-ion cells from and refurbish a whole fleet of e-bikes 😉
(For legal reasons, this is a joke)
@ascentale @InkySchwartz @bikenite A3. Yes and no, because ultimately they *can* be replaced one way or another. They have specs that no amount of custom connectors can defy. The main question is whether governments will keep it illegal because of DRM.
@ascentale @InkySchwartz @bikenite
A4) not particularly, but then my battery is a very common industry form factor and the charge port is the very common barrel plug. Yeah, the connector to the bike is unique to that brand, but there exist aftermarket adapters for $20-25.
Stay away from brands with weird charge port setups. A buddy bought a last years model from a dealer, without charger, then realized the charger was $250 if you can even find one. If the Grin Satiator's (aftermarket charger) adapter set isn't compatible, that's a red flag.
I don't worry about DRM: you can't DRM an electrical connector, at least not in this country. Plus any brand pulling that shit would get crucified. This ain't John Deere.
Finally, you can always try replacing the cells in your battery, they're bog standard 18650 or 21XXX (forgot the exact num), same as used by electric cars. Getting the wiring right would be tricky, and the downside is that your battery is no longer UL listed (some HOAs require this). #bikenite
@ascentale @InkySchwartz @bikenite
A3. Batteries are consumables, they will fail in some way at some point. The question is how long you can make them last and whether to replace or repair.
I hang out with ham radio folks who deal with batteries and battery management systems all the time, my guess is is that when my e-bike battery gives out it turns into donor cells for someone's radio project.
@ascentale @InkySchwartz @bikenite
A3) Yes! example: Bosch says they'll keep making batteries 5 years past last shipped bike. Thankfully Tern Shorthaul is still using the old batteries, so the clock isn't ticking yet.
But a bike like the GSD should last 20 years. It would be dumb to junk it because of batteries.
I know there are rebuilders, but also U/L listings and apartment owners. Heck, I can't even park a U/L listed bike outside on the grounds of the Xcel hockey rink (MN Frost & Wild)
@ascentale @InkySchwartz @bikenite
A3. Are we talking about physically not capable of being removed and replaced, or proprietary and out of production? The first (like an iPhone or MacBook, to pull some examples completely at random out of the hat) would be horrible, because the batteries are very attractive targets for thieves.
@oheso @ascentale @bikenite The first one.
@InkySchwartz @ascentale @bikenite Yeah. It would be stupid (IMHO) for makers to do that because then thieves would just steal the whole bike and hack it apart to resell the battery. Which I guess makes it nearly certain?
@ascentale @InkySchwartz @bikenite A3: no, because the Chinese manufacturers can't play that game so in the worst case I can always flip parts and make a franken-ebike out of whatever I have.
But since I Lego-level DIY these things out of bits bought on and expect that to continue, I can't see it ever happening.
It would annoy me a lot because I prefer to carry a bigger battery using LFP cells than the fire-in-a-can style ones others love so much.
@ascentale @bikenite A3. I'm glad to see there is much confidence that this is not possible for a variety of reasons. I am not so certain since I never thought cell phone batteries would be non replaceable I also never thought BBs would fail at less than 1000 miles.
And yet both are true.
@ascentale @InkySchwartz @bikenite this is a big problem with batteries, motors, and all the other random custom parts e-bikes use that will be impossible to get when the company comes out with something new next year. Mostly I worry about the DRM on batteries and motors though, and the custom mounts for all these things (which are all patented so in theory they can sue you if you make a replacement motor and battery and try to re-use your frame).
@Nicovel0 @dioramic_life @ascentale @InkySchwartz @bikenite that said, be careful with those conversion ones. Great that there's no DRM, but I've seen a handful that were outright dangerous, or just so poorly made that you're going to have to get another one every few months. Many (most?) shops won't work on conversion for liability reasons too, so make sure you can do everything else on the bike you'd need.
