Re: Making my first Motorcycle Conversion

G'day Henry. If it helps you to get started, I have a NOS EVT 4000e you can have for $500. Never been on the road, never been registered, 2km on the odo. Missing swingarm & hubmotor. Originally designed to take 4x50Ah lead batts with room to squeeze in a 5th. I'm in Melbourne as well. PM me if you'r...

Re: GM retreating into its shell ?

Yeah HH, you got me there.... Sort of. It's got the "Holden" name on it, but no "Holden" parts. Chassis is custom, sorta like a NASCAR stocker, engine is Chevy, drivetrain, ZF race, suspension is Bilstein ( I think ) & body panels are Opel.
No Holden in there mate.

Re: GM retreating into its shell ?

I,m disappointed, but not surprised. A few years ago the most loved Aussie cars were the Ford Falcon & Holden Commodore. Problem was, as popular as they were, the public stopped buying them. Ford respectfullly retired the Falcon. GM rebadged an imported FWD that isn't even built by GM & hoped no one...

Re: Ebikes are they AC, DC or?

Ok. So there's AC buzzing around inside the coils of all motors, be they 3 phase AC, induction, pm brushed DC, BLDC or. universal AC/DC. I can accept that. 3 phase AC has 1 phase feeding each coil all the time at a constant frequency, 50 or 60 hz. A BLDC controller feeds pulsed DC to 1 coil until th...

Re: Ecoreco M5 forkplay

Hi Galcohen.
The play is most likely from wear on the folding lock pin or in the latch hook. If the head bearings are loose, you'll have to remove the front wheel & mudguard to get at the adjustment. Hope this helps.

Re: Ebikes are they AC, DC or?

The controller sends pulsed DC to the phase 1 coils, Then switches to phase 2, then phase 3. The confusion rises because there are 3 sets of "phase" coils but it's not 3 phase AC.

Re: on-off ignition switch

Fuses & connectors, over time, can grow a thin layer of oxide corrosion that's basically a resistor. The resistance restricts the current down to enough to trickle charger the caps in the controller to wake up for a moment but when they are discharge the controller shuts down again. A bit like a tor...

Re: on-off ignition switch

G'day AM. I don't think it's the switch, though I bow to Amberwolf's wisdom. I reckon it's in the battery feed circuit. Look for a bad fuse, loose, melted or corroded fuse holder or a melted / corroded connector. If the fuse is a glass tube type & seems to test ok, try replacing it. I've had them go...

Hey Roni.
Have you solved your problem with the 168 yet? If so, please share with the ES community. We're here to learn from each other. If not, where are you up to. I or someone else here may be able to help. There's a lot of talent at ES!

Re: Lithium battery upgrade for mobility scooter

You could put a resistor in series with the gauge. With your batt discharged to what you reckon is the safe minimum, use a decade box in series to work out the resistance that makes the gauge read empty then wire in that value resistor.

Re: Lithium battery upgrade for mobility scooter

Hey DB. Standard mobility chargers have the third pin ( ie, inhibit ) shorted to positive in the plug. If your XLR charge socket has 3 pins, you could do the same thing & power the fan from the middle pin whenever the charger is connected. I used 4 Fusion batts in my EVT 168 with limited success.

G'day boys & girls. First, here's something you might consider. One of reasons mobility scooters use lead acid batteries is all that weight down low helps stability. 'nother thing you should know. The XLR charge socket uses the third pin ( green wire ) as an inhibit signal so the scooter can't be dr...

Re: EVT 168 doesn't run

G'day Rony. First isolate the fault to the motor or controller. It's probably the brushed motor ie: 2 wires. Does the wheel spin freely? If not it could be a seized bearing, jammed brushes or debris between stator & rotor. If ok, unplug the Anderson for the motor. You'll find it behind the right han...

Re: Hoverboard vs e bike battery and charger?

42v out of a 36v 2a charger isn't necessarily a fault. In the constant current stage, the charge will adjust the voltage to supply 2a to the battery & that could be up to 42v. As the battery reaches around 80% the charger switches to constant voltage stage where it adjusts the current to maintain th...

( Sigh ) And we wonder about all the hoverboard fires. DON'T TRY IT!!! You could destroy your battery / bms or start a fire. "Good" chargers work in two modes; CC ( Constant Current ) and CV ( Constant Voltage ). In CC,they apply whatever voltage is needed to deliver the rated current for fast charg...

Re: 100A Contactor Burned on First Try

G'day rg, maybe I can help. Was the contactor rating DC or AC? The way they switch can be different. DC switches "snap" open quickly to kill the arc while AC switches open more slowly to let the reversing current quench the arc. Take a look at those old style "scissor" or "blade" type switches used ...
