Re: Converting 24v charger into 48v charger

why don't you tell them to send you the charger you ordered? It was my mistake, not theirs. I accidentally ordered two 24v chargers instead of one 48v and one 24v. I just remembered that I know a person with the 48v version so I can probably borrow that and compare them and see if there's more to i...

Converting 24v charger into 48v charger

Hi, I recently bought a charger from greenbikekit.com That was suppose to be 48v. For some reason I ended up with a 24v charger instead (probably my fault since I was also ordered a 24v battery and a smaller 24v charger at the same time). Since it looks like the chargers are pretty much the same I w...

Re: 9 FET 72V Infineon Brushless Controller (LYEN's Edition)

The controller isn't in a position where I can easily open it unfortunately. Last I opened it I forgot to take a picture.

Re: 9 FET 72V Infineon Brushless Controller (LYEN's Edition)

I have now measured the shunt against both the precision shunt from grin tech and my multimeter and I'm positive that the actual shunt value is 1.36 mOhm

Re: waterproofing wires & controler , how do you do it ??

Can I protect the controller with polyester (fiberglass resin)? I'm thinking a thick layer of this stuff covering the whole circuit board would be very efficient water repellent. I know this is normally done with epoxy, but polyester is easier to get in big quantities and cheaper. I don't really kno...

Re: Cycle Analyst V3 preview and first beta release

Instead, the function RPM Cntrl should enable the throttle but OVER THE FULL RANGE , and not just 'full throttle'. Only if the rider pedals, the throttle should become functional in this mode. Please Justin, change the firmware to this point, or this feature is useless to European riders. I have be...

Re: 9 FET 72V Infineon Brushless Controller (LYEN's Edition)

Cheers The shunt value seams to be off though. Seem to remember that Ed gives you a shunt value based on the value of the manufacturer given value. Off the top of my head, I think they are 4 MilliOhm shunts, so 4 in paralel will give you a quoted value from Lyen of 1 MilliOhm. But all things have m...

I'm also glad of course that the 9Fet is still for sale because it is a good controller that kept cold while pushing...

Re: 8Fun CST 250w and 350w, what is the difference?

I've fitted two 500w CSTmotors and they dropped straight in to the bikes, which had 135mm drop-outs. One of then was an upgrade from a 350w CST: I hooked out the 350w wheel and dropped in the 500w one. I would therefore say that the 500w CST is made for 135mm drop-outs not 150mm. Interesting. Was t...

Re: 8Fun CST 250w and 350w, what is the difference?

Thank you Tom. You may have saved me from all the hassle I would have got if I bought a 500w version. According to BMSBattery the 500w CST fits a 135mm dropout, but I have learned long ago that BMSBattery has no quality control on their specifications. I'll probably buy the 350w motor kit from green...

Re: 8Fun CST 250w and 350w, what is the difference?

Howdy. From the correspondence I have had with Bafang in the past, I believe that the only real difference between the 250 W and 350 W CST is simply the variance of power that is being put through it. You may notice on the Bafang website, that the CST is rated from 250 W to 500 W. The smaller power...

Thanks N!co, I didn't know about that one. With all the hills around here I think I'll go for a geared hub though.I have a small DD already (the SmartPie) and that one stalls on every hill.

Re: 8Fun CST 250w and 350w, what is the difference?

As far as I know, there's no difference between 250w and 350w apart from the marking, but why not get the 500w and stick a 250w label on like we have? The 500w one is quite a bit more powerful than the 350w one. I have both, so I can compare. I'm not sure that Motomech's right about the CST breakin...

Re: 8Fun CST 250w and 350w, what is the difference?

It's just a BMP 350 with a different cover. Be for warned however, there have been reports here of breakage of the Cassette mount where it joins the vertical plan of the cover. This, of course, happens to many hub motors, but early reports would indicate an fairly high rate of failures with the CST...

Hi, I have been looking at the CST motor from greenbikekit.com because it is the only motor I have found that accepts a normal cassette.

I am about to upgrade my bike to 74v lipo, but I'm using the Thun PAS sensor. As far as I understand I will fry the CA3 if I have the Thun connected while running at 74 volt. So to do this I need to cut the 10v supply (white wire) and feed the Thun with 12v from a dc-dc step down converter? Is this ...

Are you running the speedo signal from hall signals on a direct drive motor or with a magnet and sensor? It's the DPS version so no hall signals.

Re: Cycle Analyst V3 preview and first beta release

I just tried the B20 software and I noticed a strange behavior. When I give full throttle with the wheel raised from the ground the CA will cut power for half a second just before reaching full speed. There are no limit flags raised that I can see.
