Endless Sphere

Well a few years later and they are still running . Kept charged by a measly 300 what of solar cells. I checked the fluid levels in them last month.. I did them when I put them in...whenever this post was new..and only again this year, Need about 30 litres of distilled water :( No plates were uncove...

Just had the misfortune to have to look at a Cytronex bike , a kit built on a nice little Cannondale Motor labelled as 180W 36 volt front motor, geared Three magnets on RSH of motor and sensor on the crank Unknown controller looks 6 FET, stuck under th bottom bracket. two nice little switches on the...

At least a few years ago, the Shimano ones were selling in the hundreds of dollars... no thanks

There are abundant cassettes available with 11t high gear-- probably most of them. But what you have isn't a cassette. It's a freewheel. Your wheel can only take one or the other, and most hub motors take freewheels. Ah well OK , I got it the wrong way around. So in that case, when I did that, how ...

Seem to remember that there was no other option at the time. Think it was that there were no other cassettes available with an 11 tooth . There was a shimano that was made but almost impossible to find, and if you could find New old Stock, they were selling for hundreds of dollars. The DNP was the o...

I wish I could help you, but it has been nearly 5 years since I did that.

I honestly have no idea now, sorry

Good luck

We have all been in your situation , and have been helped in similar ways

Glad it is all working

I'd probably wire the PAS to these.
+5v red
GND 6 to black
TA to the other one

The following question is about pas connection without any display: Yes, I fully understand that Is the TA as seen (foto) there, is it compatible with my pas (standart) with magnets? Absolutely no way I can say for sure..the only way is to try it and see and risk damaging something if wrong. It pro...

I f you want to open your controller and look, you might be lucky... If it happens to be labelled PAS, then you'd need to solder a wire to that pad, and another from a 5 volt feed and another to ground Get it wrong and you will of course risk screwing the controller on that controller it was labelle...

]Thanks, but it's still not enough, one told me that if I'm wrong I could do damage, the socket of the controller where I should connect the 3 wires of the pas is this: 1 Battery Voltage Vcc-L (red (I think it's battery indicator, my 48v., and I do not need to use it) 2 GND / Shunt + ve (black) 3 S...

Exactly as Amberwolf says, you can’t connect it to the 6 pin CA connector It can only be connected to the dedicated PAS connector. If you don’t have one, as he says, there maybe a PAS pad on the board, but I’d guess that at your level of knowledge of this stuff, you have slim to zero chance of findi...

Too long ago to remember
But any PAS with 3 wires will be basic
Voltage in. Probably 5 volts
Ground
Signal out

If it is dropping to low voltage then coming back up, then that is the Battery management system circuit board (BMS) within the battery pack shutting off the battery output when under load. Either because of too high current , possibly too high battery temperature, or most likely, one cell in the ba...

yes, I found the 20-200 volt optional reference too,
Wondering if a resistor mod does the swap to 200v ??
Have sent Grin a msg too, as can't see any info on how to change it

Hi After many years...(Since the Xlyte 540x group buy) I am finally getting around to putting the bike together.. Have an old V2.23 CA and a lyen EB224 Controller. Going to run at ..34-35 series lipo...147 volts. No other accessories..just the CA and a throttle Can I run the CA at 150 volts direct f...

This has three wires. grad 12 volt Data line. The bike is 36 volt and there is no battery voltage at the display/ control unit. Only 12 vol tin and the data out. So it does seem that originally any light switching was done at the controller, but this controller does not appear to have that facility....

I probed the various outputs on the board and nothing changed with activation of th e'light switch'.. but now the lady after riding th bike for a few days ..after coming form the bike she had for a few years..a Twist and Go style..has decide that this PAS style bike is really a gutless piece of shit...

I had been told on the Pedelec forum that there was in fact an actual switch output of battery voltage on the board, and not via a switched encoded signal to the the controller to switch the light. The opinion was that some of the bikes with OEM lights did take power direct from the handle bar unit....

Hi guys I just picked up for free a generic Rayleigh Velo trail e-bike...low powers from geared hub 36 volt PAS only bike It has a little 3 button handle bar control unit As in pics below Power Assist level lights on/off Now even the manual says that the lighting part is not connected on this bike.....

probably only if you can find a used one
Burtie does not seem to be repkyong to stuff on here or private e-mail any more. I tried contacting him a few months back and had no reply.

Can someone confirm what I am thinking ...regarding charging LiPo with a BMS with a single cell balancing current of 168mA (+/- 20mA). BesTech HCX-D131 If I want to ensure a nice balancing charge, I'd set up a charger to charge at that sort of current, so if I set a charge current of say 125mA I'd g...

Just trying to figure out if hall timing shifts the phase waves relative to eachother No, or if it shifts all of them together. Based on your posts and others in this thread I think the former is the case, but I'm trying to confirm. Correct, it just shifts them all.... But the controller itself is ...

- does advancing/retarding the timing actually change the phase angle of the waves? If you do know the term Phase angle control , as in theis device here: http://nz.rs-online.com/web/p/thyristor-power-controller-assemblies/0841924/ which I believe controls power by adjsuting the relationship bewtee...

The tool actually creates a synthisised hall signal..it does nto actually 'capture' and send out the original. Also it does actually 'advance' the timing..that would be impossible without the ability to see in to the future. In effect, it see s the incoming signals (it intercepts all three) then del...
