Wouldn't be surprised the 36t works fine, so close to the 34t

I went well over the max my derailleur (XT M8000) is rated for (46t) putting...

Very nice clamps - FWIW here's an off-the-shelf solution I've used for not only batteries but even water bottle cages LOL:

This is what the clutch is suppose to look like - the pawl on the lower right is just cocked off to the side - would be rotated to the same as the other...

This is the basic outline - best to put a small (e.g. 0.1µF) ceramic capacitor from gnd to +5V close to the op-amp

This would do the trick:

On that note I'd also recommend strapping the battery to the frame to keep it from wobbling, etc

Voile straps work very well for this and...

Excellent - we appreciate the update... if you do figure out whether it was the buttons or the display itself, let us know if you get the chance

@stts

I presumed you had a bike, mebbe newer to the game, possibly living in cold climate (riding season here is pretty much opposite most...

That kludge has served exceptionally well for quite a number of years and many thousands of very hard miles - there's some real world experience for ya...

@stts

Mmmmkay - personally I don't get worked up over posts on an internet forum and sure as heck don't go into full flame mode even on the...

stts - Since some of the posts don't really jive with the experience of many of the other electric bike owners here and elsewhere - out of curiosity,...

Well it's good you have a solution that works for you

I know for me, once I did my stans thing and never got a flat again, it took that whole...

[AZguy]

I like the way you put it

Regardless, without coulomb counting (totalizing the current over time) and measuring amp-hour/watt-hour, voltage...

So as we expected the charger is definitely a "52V" charger but as you already realize 55.8V is not a normal voltage for the charging to stop...

Unfortunately chinese documentation is terrible and often not to be trusted... a quote from a manual I have:


What gobbledygook...

[AZguy]

I'm going to strongly disagree that a voltmeter is only useful for troubleshooting

After all, the bar graph on the display is just a crude...

If luna has one then the driver it likely better known but as long as you can sort out the driver any one should do fine.. I've even built them

You'll only be able top probe two phases of the three and voltage only but you should see the same basic signal on all three and if one is dramatically...

There's a setting in the controller for the speed meter so I'd guess it's for that and if it's set to external it's just the wheel magnet (some might...

[AZguy]

I would get a programming cable for the controller - display settings will only get you so far and reading the settings before and after you change things...
