Its been through many iterations while i've tought myself how to use CAD software, some basics on bike geometry and what hardware I wanted to...

    An EE's final (uni) project - building a e-'bus'

    So I've been lucky enough to be selected to essentially build a small, low speed (50-60km'h) e-(mini)bus, to carry <10 people. We're expanding/improving/replacing an existing 3 wheeled ebus. We've already got some ideas, and a existing converted electric car for a test bed (we'll be putting our...

    any tips for recovering lipo batts and controller diagnosis.

    for the second time in less than a year i went to charge my bike's batteries, only to find that there wasn't enough voltage in the cells to even switch on the battery medics. this time atleast, it appears not to be my fault (last time I left a swichmode PS attached), the controller was not left...

    HK brings out a 14s 250A controller - practical ebike use?

    HK just brought out a 14s 250a controller in their 'dlux' range. considering I've heard of people using the smaller 80A HV ones on ebikes with success this is an interesting development... like most hk stuff I'm guessing 250A is very optomistic... but would still be pretty mean at 100A. looks...

    Battery storage - lipo - high temps?

    After hunting round the net, the only reference I could find to storage is that cold generally = better... but I couldn't find any references to the risk if stored in higher temps... Im leaving overseas for a month, and jan/feb is generally the hottest months here in AUS. Peaks are around...

    0V lipos, back from the dead?

    some of you will remember that a few months ago I left the 12v swichmode power supply connected to my 24s lipo pack and subsequently drained all but about 4 cells down to 0v (or a few mV, so near enough to), those 4 cells spread around 4 different packs were at around 2.5v. I did consider...

    alternatives to sbp for wide BB's?

    Does anyone know of any other retailers (preferably closer to australia) that can supply the extended BB's like sick bike parts 150 and 200mm units? ive trawled through the usual's, like ebay etc etc, but the extra wide bb's seem pretty uncommon. cheers.

    problems with a RC CA - binary throttle - help needed

    I've posted on the RC CA thread too... I've got my RC CA wired up and spinning a 6374 motor, running with a hobbyking SS 190-200 ESC. the problem is the RC CA's output to the controller seems to be binary, either with a T of .8ms or 2ms, nothing in between. the throttle etc all seems to work...

    well shit. there goes $300 down the drain. I am an idiot.

    Well. I'm one unhappy camper right now. I just discovered I've pretty much killed $300 worth of lipo. I had my 24s 10ah pack all wired up still, but since I hadn't fixed my bike up, and I wasnt likely to any time soon, I'd removed the pack from the bike + disconnected the controller. The cells...

    mod a plug in CA to 'see' the charging amps?

    I read a while ago about dogman (i think) wiring his bike so that the current form his charger runs via the shunt of his ca, so he can see how much power is going back into his pack each ride. ive got a plug in ca, so is it possible to have it 'see' the regen current? I'm guessing that'd involve...

    Audi weigh in to the ebike scene... with style!

    semi advanced q about motor efficiency and rpms

    I've thought, (as it seems most people do) that a high turn count motor means greater torque for a given amp input. I've been scratching my head for a while now as to why some members insist this is not the case, that for a given motor, say a HT run at 100v 40a, it will have almost the exact...
