Countless companies and industries enjoy making up scary stories when it comes to justifying their opposition to making it easier to repair your own tech. Apple claims that empowering consumers and bolstering independent repair shops will turn states into “hacker meccas.” The car industry insists that making it easier and cheaper to repair modern cars will be a boon to sexual predators.
Almost got scammed by Rad Bikes this way. Battery mysteriously failed 10 months into their 1 year warranty. Rad Bikes accused me of sabotaging the battery and refused to honor their warranty, but “generously” offered me free shipping on a $300+ replacement battery. Turns out the off-the-rack fuse they use blew; identical down to the manufacturer to the ones used in cars. Replacement fuse was <20 cents and fixed the problem instantly.
Do you recall the specific fuse? There was someone asking about ebike battery fuses on !micromobility@lemmy.world a while back. Wasn’t really sure what to tell them, but automotive fuses make sense.
On my RadCity 5 Plus, it was a 10 amp red mini-blade fuse. I had a “variety pack” in my car that I’d gotten at a local auto part store, but looked it up any way, just in case. This may be different on other models/batteries. Ironically, it did require a warranty voiding opening on the battery casing. :-)
Fwiw those “warranty void if opened” stickers are not legal
Fwiw, any statement like this is worth less than what you’d have to pay a lawyer…
Wait a minute, why did the fuse blow in the first place? This might be a safety issue and should be handled by the warranty.
There might be a reason. But if the reason really is a safety issue, then it would also blow the second fuse.
That is what fuses are made for.
