    Best place to buy Headway 38120L flat tab battery?

    Help! I am in trouble - I have just built a new 16S battery out of 38120L (Flat Tab) Headway cells - but one of them is not happy, and I need to replace it. I am finding it very difficult to find somewhere that will sell me 1x 38120L Headway cell and ship it to Australia at a reasonable price...

    Weird BMS issue/problem

    I have just built a 16S 10A battery pack with Headway 38210 cells. I have put this BMS on it: http://www.evassemble.com/index.php?main_page=product_info&cPath=6&products_id=211 Now, when I wire up the whole battery, and plug in the BMS, I get a red light in the BMS itself (see photo). But...

    Kabbage eBMX#1

    My nephew lives on an acerage just outside of town, and wanted a bike to get around the paddocks. He found this BMX on hard-rubbish and rescued it... Chain could do with some oil one decade. But cool - that top bar looks just the place to lob a 48V12Ah headway battery, doesn't it? Voila...

    C'lyte 3540 in 20" BMX rim, spokes?

    I am thinking of putting my big crystalyte 3540 into a 20" BMX rim to make a little fun electric farm-bike for my nephew. I have used the calculator on Ebikes.ca, and recon it is still capable of 40kph at 48v and 30 odd amps; hopefully some good torque in the 20" rim. Any advice about spoke...

    new ebike.ca controller random cut-outs?

    I have just completed my second bike which is sort of going OK, but I've come across a weird intermittent problem that I would value some ideas about. I have one of the new ebikes.ca sensor/sensorless Infineon controllers with the little red flashing light on it (It flashes red at rest, and...

    Massive pothole comprehensively frocks BPM

    Oh my. Back on the bike after about a year off, and on my third (count'em: 3) trip to work, I've encountered a massive pothole on Victoria Parade at about 40km/hr. It snuck up on me, and the rear wheel took a very big hit (and my battery is over the rear wheel too...) Well, it's...

    Least-space method to join tabless batteries

    I have just got my Headway 10Ah 38120 cells from evassemble. I got the ones without the screw terminals to save on space. I am planning to make a long and skinny 16S battery from four groups of four batteries long, placed along a central spine arrangement. So what's the best way to join...

    Kabbage Commuter No. 2

    Well, it's been 13 months since I broke my humerous falling off a skateboard, and so unable to ride the bike - I went in for surgery last week to have the arm 'mended' and they got around to looking at the X-Ray and saying 'well hell, it looks like it is acutally healing now - so no surgery for...

    Pushbutton throttle?

    I am about to begin a 'bare bones' build - everything as simple as poss. Adrian_sm has done some nice 'pushbutton' throttles for his friction drive, so thought I might do something similar. I tend to be either full-on or off the throttle, so I think this would work for me. I am running one of...

    Change C'lyte3540 to BPM

    Hi All, Finally took advantage of the holidays to swap out my C'lyte3540 (see http://endless-sphere.com/forums/viewtopic.php?f=6&t=39940&hilit=avanti) for a BPM 11pole hubmotor. I guess I wanted something a bit lighter than the Crystalyte, less 'obvious', and I was only ever running it at...

    Battery bag fail (Melbourne Aus)

    Came across this abomination in Fairfield (Melbourne) this afternoon! Nothing a bit of packing tape can't fix eh? Not convinced how waterproof the whole system is. Any E-Ser game to claim responsibility?

    Avanti Commuter - Update

    Well, I lurked here for long enough to find out how to build my first e-bike, so thought I should finally share what I built. I wanted something to replace my Honda CR600F on my daily commute (15km round trip). I looked at all the 'commercial' e-bikes, but decided most of them were just...
