I'd assumed it was a rheostat
That's what I thought a throttle was, but when I saw that @vidtek had linked this product with a non-latching push button...




... I wondered what sort of bike you had, and whether that'd work as a throttle... and if that product did, a button from a Hornit horn would probably work your throttle too, with the advantage being it could be placed right under your index finger on a handgrip, where mine is conveniently located to operate the horn at a moment's notice and zero effort - I've seen bikes advertised with a non-latching "Boost" button, which is really just a on/off throttle. How those work, or indeed how ebike throttles work, I don't know. Maybe a throttle expert will enlighten me.

Our bike has an XF07 kit from Woosh, Lushui controller. It came with throttle ready plugged in, I don't even know what connectors it's using. I should ask Woosh and I'm sure they'll give a clear answer.

Please do post and elighten me! My BBS01B throttle has three pins, and I was half thinking of whether to short a couple to see whether a non-latching push switch could be soldered in, to work as a simple push "Boost" style throttle. But I don't use a throttle anyway, and am nervous in case I kill the controller again... on the other hand... I do have a spare controller in storage...

If I tape the throttle down at full, I should be able to splice in a non-latching push switch for instant full power.

I found this: how ebike throttles work:

wind and solar is bs you cant store any of it and no sun or wind means 0% production and no back up they could not make enough cells to even make a batt back up possible and the cost would be insane as will loose capacity if not explode if left to long as only takes 1 cell to go bad.

if all this stuff was this good then why does china make all of it what we buy but still builds coal and nuke power stations lol.

we should join the republic of china and get fast food direct from china via ICBM missiles that can drop the drones from space, cant get faster than 18000mph :p
I'm late to this party, but saw @soundwave's comment:

Wind and Solar energy CAN and IS being stored for when the sun don't shine and the wind don't blow: 698MW of lithium stored green energy.

China builds and keeps using coal for the same reason Britain did after WWII. We had an abundance of cheap coal, didn't then have North Sea gas, and given our post-war debt couldn't afford to import oil in the volume needed as an alternative.

I can't find to its capacity, but
The Dinorwig Power Station is a 1,728 megawatts pumped-storage hydroelectric scheme, near Dinorwig, Llanberis in Snowdonia national park in Gwynedd, north Wales.
.

p.s. did you mean 698MW hours? I see your reference also quote MW.

I don't know - it's what they state in their prospectus. It doesn't produce, it's simply buffer storage; more being built (see their interactive map of existing and proposed sites). The Scottish rely heavily on hydo.

It's not the only cluster of energy storage facilities in the UK. I'm only aware of this particular group because it's a conscious part of my Pension fund, as are wind and solar farms. Future growth to help meet the UK's green targets could well be hampered with Hunt's new 45% windfall tax, and Dividend taxes meaning "ordinary folk" like me won't be putting any more of my pension into it.

Looking a bit more I found In addition, Dinorwig is capable of moving to peak capacity from standby in less than 16 seconds, with an energy storage capacity of about 9.1 gigawatt hours (GWh).


That's more than I had guessed; 5 hours at full capacity. It may not be able to use all its capacity at full power though. I knew the fast startup was important and had expected that the delivery time was much less.

I guess lithium batteries can provide power even faster; though goodness knows what extra complications there are on handling batteries on that scale.

you could never make enough batts for a country's power demands and after so many years would need to be replaced at massive costs so it is not viable option or china would already be doing it but no they build 80 coal power stations a year and make most of the wind turbines and solar panels and have the most evs in the world yet still burn the dinosaurs to charge there batts it will never change any time soon.


out of warranty you are screwed as like a tractor every part will be serialized so even if you get the part it wont work unless it is paired to the car with the dealer software.

it is all about control and forcing there corporate agenda for profit like my bike is nearly ten years old and even tho they make the new smart frame batts for my bike they will not work so bin it and buy a new ebike for 10 grand id rather walk or buy a horse that can take a 5kg dump in the middle of the road :p

It might work ok. If it doesn't, you could try substituting throttle with 20K resistor/ 5K linear potentiometer as in diagram below of one suggestion for push button throttle (from ES) that gives the required 4.4v full throttle/0.88v no throttle signal required by many controllers. (or some controllers can give an error signal). 49544

Thank you for yor post, and for uploading that circuit diagram, which I've squirrelled away for reference.

Out of interest, and because at present my bike is conveniently located next to my computer, I held down the throttle (after cleaning the contacts with 90% isopropyl alcohol - it's been disconnected so long that the contacts had oxidised a bit, and the throttle didn't turn off after turning on, which cleaning the contacts has fixed) and switched the BBS01B system on: It didn't work - therefore my idea of splicing in a non-latching push switch to use as an instant-on/off throttle, won't work on my BBS01B.

However, I think that if I held the rear wheel off the ground, switched the system on and then taped down a spliced in push switch and also taped down the throttle, the spliced in push switch could then switch the throttle off and on. I'm starting to feel grateful I don't need a push on/off throttle, but @sjpt may be interested in making one, to make life easier for his thumb.

The last kit I fitted was supplied with a newer/different version of the Wuxing Throttle. It can be fitted in either left or right side, or either way around giving more options/positions.. I fitted it on left side with pressing down for on and for me anyhow, its not as tiring. Against that, its easy to accidentally operate switch in this position.

I'm rubbish at soldering
I was completely rubbish at soldering - killed a controller. For me, initially using (acid-free) flux made a huge difference, and after much practise soldering using flux, I no longer need any more flux than what most solder is cored with. Here's an interesting post by @StuartsProjects about soldering, which I found very informative:

If you are struggling with soldering, make sure you are using leaded solder. Not green I know, but the lead free stuff is a nightmare to work with. Often it has a higher melting point and unless you have very professional equipment, you'll end up with a mess. Also, make sure you are using a soldering iron with enough grunt. I would use at least 60W to heat up spots fast. Modern PCBs take heat away so quickly, a 20W iron is hopeless.

Another tip for desoldering - ADD some leaded solder. It reduces the melting point of the solder on the PCB, aids heat distribution to the soldered spot and it allows you to remove the solder more easily.

Yes, I forgot to mention that Welling 70% lead solder was a lot easier to work with. Weirdly, pretty much any solder works for me now. But I'm no soldering Yoda: can do cables and connectors, can't do fine circuit level - but I expect if I needed to, I'd learn that too.

Cheers, that's a good one. Hadn't heard of that before.

70/30 solder should work ok .
A 60w iron is plenty for battery work or small electronics , for larger wire use a wide flatter angled tip or one of the larger round flat tips with a 3mm flat face .
Pre soldering the tip and applying more solder on an existing one helps to desolder easier by distirbuting heat quicker as already mentioned.

For thick wire connections for a battery example it is better to fan the wire out to solder on to a nice bed of wet solder. If building say a battery the best thing is too pre solder any wire to the Buss bar and then spot weld the Buss bar to the end cells.
