Like this perhaps? Only it isn't about blocking wrong chargers. Some are pressing for enforced non-interchageability between brands and distinct sockets, presumably several per brand (of which there are at least a few hundred). As Bosch customers know that's all about capturing the market...

A house fire thought to have been caused by an e-scooter battery spread to seven neighbouring properties (BBC news). I'm sure you're right on both counts. Aside from opening the case, both accidental and deliberate mis-charging are foreseeable misuse and in those cases the product shouldn't be...

Agreed when it comes to gross cases but both your examples would simply wear batteries out faster if they had adequate (ideally dynamic) protection built in. Blaming the consumer keeps attention off the product, as does blaming chargers. Certification would be especially burdensome compared to...

Do they cut out only when the motor's working hard such as climbing? That and both bikes being affected could be down to the batteries sagging through old age or long use. If it cuts out with gentle riding on rough tracks the battery connectors can be replaced separately for a tenner or two...

If ever there was a dark art it's hub motors in steep terrain. The actual change in assistance may be small but if the remaining gradient is near your limit it's a big deal. No wait, councils are a dark... something. I explained the above and still we got a new 'road table' on our 12% hill...

What if he was tired and just picked up the wrong charger - jail time? The problem is that some batteries don't have adequate protection built in, if they did a wrong charger would hardly matter. The notion of a 'wrong charger' is being kept alive in the hope of them being regulated in our...

Taking the Elejoy for example, it seems a bit odd that there's no mention of the maximum current in their product page, other than in the URL, when that's an important safeguard.

To sort of answer your question, it could be worth searching the forum because one or two have been mentioned not that long ago, only I can't recall who or in which threads. You didn't say why you want one built rather than buying the finished article, as well as not explaining your intended...

That's a worthy straw to clutch at as "current" control's not as simple as speed control. With either, at the limit speed the power should fade in and out gradually to prevent annoying 'bouncing' off the limit, like when you're pedalling downhill and the bike slows on the up. It's OK for power...

Maybe brake to reach the dip ghost pedalling at 14mph so that the controller's all set for the climb? On mine brake cutoffs respond faster than PAS or speed limit. * WLT hear more. * doh, there was a similar suggestion 90 posts ago.

TLDR: Actually the government is proposing destruction after 48 hours and the public consultation closed on 8th July - it's a shame the West Midlands PCC article above didn't appear until the 16th. This seems like the government amending legislation so as to impede people's participation in...

AIUI the trapezium shaped connector ensures the 9-core comms for motor+TS doesn't get connected to a regular Julet controller lacking TS support (such as smoothing). When the battery wears out can it be second-sourced if need be, even by hacking the bottle mount? In contrast Woosh's 85TS kit...

It reads like 10S2P 18650 3500mAh making around 1kg for the cells alone.

The rules do convey these aims in a 'between the lines' sort of way, and stipulating 'rated' continuous power seems not a bad way to deter drag racers while permitting cargo bikes. Kinda "Don't be an arse or outright lazy". With the green transition adding a new reason to encourage e-/cycling...

> master class videos from the professionals Here you go, and a dab of grease would surely help.

Perhaps they're intentionally working behind closed doors, which seems to be a wider problem with this BSI PAS, the OPSS's upcoming standards reviews, the PR&M bill and who knows what else. It isn't easy to find out what's in the pipeline or offer input. This isn't good because almost all the...

Yes EN15194's probably easier. For me, using 1P 20Ah cells, the benefit of 52V is being able to add capacity in 8% steps, rather than having to double weight going from 1P to 2P. That won't apply widely at present but standards should take care not to needlessly exclude technologies...

EN15194 isn't a legal requirement, although meeting it is enough to presume compliance with the law, EAPC regs 1983/2015, which itself doesn't limit voltage. So technically 52V doesn't appear to be illegal. EN15194 is meant to align with the Low Voltage Directive (LVD) which covers systems of...

Let's hope the LBS hasn't been following this :)

I don't know any mech eng so a pinch of salt is called for, but you said all the bolts were tight... what if a mating surface weren't flat but slightly convex, would that snug up tight but rock under load? Like if a caliper mount were badly machined? On your video the rim's moving a lot, so...
