    Known to Work Brushless Motor/Controller Wiring Diagrams

    Nobody? Does anybody know then if the wiring for Crystalite 4 series is the same as for Crystalite 5 series, as we have the wiring for infineon to 5304 on this thread already... (really don't want to dig out the fuses and spreadsheet again!)

    What's my best replacement motor?

    My commute is 3-6 miles depending which way I go - there are a couple of hills which my 350w bafang coped with just fine (ahem!) I have a 3 speed switch fitted to my infineon controller which gave me > too slow to use on "1" > about 17-19mph on "2" > about 22-27(down hill) on "3" with my...

    What's my best replacement motor?

    Ok, like everybody said would happen, my 72v/infineon controller combination has blown up my 350w Bafang motor. I need a replacement in a hurry, but am baffled by the choice on offer... I'd rather buy from a European distributor to save on delivery time and cost... I've been looking at the...

    Just saw this and thought of you guys

    Err wow - those powabykes are really ugly! What I liked about the Tato bike was that it was a simple, clean design - unlike so many e-bike frames... ...Just like the ones everybody else posted - well, each to their own I suppose!

    LiFePO4 pack rebuild - what are my options?

    Well, Dogman - it looks like you were right! I rebuilt the pack, using spring connectors, bus bars and plywood. I recharged every single cell using a 3.3v Camera charger, put it back together, connected it in serial and WOW! I got the 72v buzz I'd been looking for - for about a mile - then my...

    LiFePO4 pack rebuild - what are my options?

    OK - just gave a single cell a bit more manly a test - I hooked it up to a car cigarette lighter - I'm not sure of the actual draw of this, but WikiPedia seems to think about 10a at 12v = 120W. The voltage sank to 3.19v immediately and the cell gave a constant 1.5-1.6A for 50 minutes before the...

    LiFePO4 pack rebuild - what are my options?

    I have very little money! This bike was working in its present form 2 years ago, it was only when I went chasing speed that it all started to go wrong(!) since then I've bought a cycle analyst, another 36v 10ah battery, 2 new bms's, 3 chargers, disc brakes, 4 battery housings ... I've spent too...

    LiFePO4 pack rebuild - what are my options?

    Err wow - that's not what other people said - I'm no expert here, I was assuming the were dead coz other people told me they were! {http://www.endless-sphere.com/forums/viewtopic.php?f=2&t=18445} I have checked the voltage going in from the charger periodically, and it's not gone over 4v - I...

    LiFePO4 pack rebuild - what are my options?

    Well, in an ideal world I'd like the 36v 10ah pack I originally paid for! If I can get a valid 36v 10ah pack then I can just wire it back up using my existing Ping BMS and charge using my existing 36v charger - plus the current switch wired in to my controller would then work properly (it was...

    LiFePO4 pack rebuild - what are my options?

    5w eBike :D gonna try me one of those :oops: There doesn't appear to be any voltage sag at all (from the 5w bulb any ways - gonna find myself something more meaty) should I load the cells individually or string them together to get something close to the load that the test device is...

    LiFePO4 pack rebuild - what are my options?

    Just tested my first recharged cell. I had it wired to a 12v 5w car brake light. It drew 0.9A for 1 hour 15 minutes before the current started to drop slightly. Voltage remained at 3.3v throughout. Now then, please attempt to follow my flaky maths and point me out if I'm wrong here. My...

    LiFePO4 pack rebuild - what are my options?

    Ok - so I've charged a couple of cells with my nokia charger and they seem to be holding steady at 3.3v thing is I've got no idea how long to leave 'em on charge for! So I've dug out a camera charger used for 3.7v li-ion batteries - this has a charging/charged led on it. Will this give me an...

    LiFePO4 pack rebuild - what are my options?

    Ah, well - this battery had been left for 18 months(!) So will my 5.7 volt Nokia charger be OK for this job? Re contacting Jimmy Wu - nah, I don't think that's going to happen ;-) Oh and links - copy the link you're linking to out of the address bar of the browser, paste it into your text...

    LiFePO4 pack rebuild - what are my options?

    This is much better news! Thanks for bearing with me Could you possibly point me at a couple of links for the exact balancer/monitors and chargers you're talking about? (The hobby king website is fairly daunting at first visit, plus - of course it'd be great if I could find something similar in...

    LiFePO4 pack rebuild - what are my options?

    I believe Fechter's "Even Newer 4-24 Channel BMS" would allow me to have 8 strings of 6 cells? I've seen this earlier model described on V is for Voltage (http://www.tppacks.com/products.asp?cat=26) Honestly - am I chasing rainbows? ;-)

    LiFePO4 pack rebuild - what are my options?

    Ah - OK, Well, my other thought was to make an 18V pack out of 6 strings of 8 cells to wire in serial with my 36 v - I reckoned that 54v would be just about perfect for my Bafang - Only question is where would I find a BMS with 6 channels (and an 18v charger) - is that viable? Can't believe...

    LiFePO4 pack rebuild - what are my options?

    Hi all, Well I pulled my JimmyWu 36v 10Ah non-functioning pack to pieces and I got lots of blue Valence saphion IFR-18650EC cells. They (were) grouped into 12 strings of 7 cells welded in parallel with thin (read sharp) tin strips. The readings I was getting from the terminals of my BMS (prior...

    OK - so what am I doing wrong now?

    Took the 'poorly" battery out of series after talking with Geoff57 - the bike works just fine as a 36V - going to have to have a think about this other battery though as would still like that extra speed. Does anybody else have experience of LiFePO4 batteries "going off" after a significant...

    OK - so what am I doing wrong now?

    Another weeks solid work on this bike and I'm still baffled :shock: So, I've wired my 2 36v batteries up in serial and connected everything up to the controller - I have a couple of obvious problems ... Firstly the batteries - I've charged them both fully and one is giving out 40V, the...

    Just saw this and thought of you guys

    it's a really good looking bike with a built in battery holder... looky: You can buy one here :http://tato.li/cssb/ - price is about £600, so not cheap - but think what it'd save you on battery box construction ;-) Truly gorgeous.

    Sanity Check please!

    OK - Belt and braces check - The black terminal on my multimeter is connected to earth. So the terminal into which the RED probe is inserted is positive and should be connected to the red charging wire from the BMS.Correct? Geoff Hi again~(!) what amperage fuse should I put into the negative...

    Thanks for the prompt replies! - any idea on number 2 anybody?

    Sanity Check please!

    Hi all, just about to wire everything back up again and am frankly crapping myself that I'm gonna blow it all up (again) - it's taken me 2 years to get back to the point where I'm ready so I'd really appreciate some hand-holding (Yes, I've made a donation!) OK - my questions are as follow: 1...
