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...

Re: Hoverboard vs e bike battery and charger?

( 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 ...

Re: Do I get a prize for the most obscure diagnosis ever?

G'day peoples. If your scoot has the lights permanently on as most do these days, try a test ride with the tail light globe removed or tail light wires unplugged. A bad earth allows 12v to feed through the tail light filament back out through the brake light filament to the controller, holding the b...

Re: cell capacity tester

Glad to be of help Tryker. That's what we do on ES. For single cells, it doesn't matter much if you use Ah or Wh. For batteries ( a "battery" is a string of one or more cells ) though, Wh more accurately describes how much energy is available. 48v 20Ah is 960Wh where 24v 20Ah is only 480Wh, or half ...

Re: cell capacity tester

I use an IMAX pro charger from a hobby shop usually used to charge RC batts. Set for 1s & the right chemistry, charge the cell then use the discharge option set to 1 amp to safely discharge. The IMAX stops & displays the time taken. A 2000MAh cell in good condition for example takes 120 minutes. 2 h...

Re: How to brake using electric motor?

Hi there. Am I right guessing you're building this kiddie car? Lucky kid. Are you set on running 36v? If 24v would be ok, you might think about finding an old mobility scooter. Non workers go for next to nothing. Often it's just read batteries. You get a brushed motor, a programmable controller with...

G'day boys & girls. The tadpole parts & 2 controllers have been claimed. I still have 5 new controllers & the 168 scooter up for grabs. The scooter has a working controller, wiring loom, 48V-12V converter, switches & other electronics on it so it's easy to work out the connections. Anyone want them?...

Re: Mobility Scooter upgrade

You need a brushed controller. If there's a place near you that services mobility scooters, they may have used controllers for cheap. The Rhino range goes up to 160 amps & there were some 36 volt models though they are very rare. I repair & service mobility scooters for a living. I've only seen 2. Y...

Hi peoples I have seven 48V 120A brushed EVT controllers I don't need so I'm giving them away. That's right, free, gratis, nothing. Six of them are new unused, one has been opened coz I'm nosy but it still works. The housings are cast aluminium & can sink a lot of heat. If you want them & you're in ...

Re: Mobility Scooter upgrade

G'day Jerome, maybe I can help. You won't get wheel spin without over volting & from memory the Rhino controller has 30v caps that would blow. It is fully programmable though. There's a 4 pin socket on the controller, often used for charging, that's actually a serial port. Red is positive, black neg...

Re: New Throttle / controller hookup question

This may sound dumb, but hey, sometimes it's the dumbest things that stump us. First, it is definitely a 12v controller, not 24v? Also, many basic controllers have a connector labeled REV. Usually. When this is shorted, the motor runs in reverse at 1/2 speed max. If there is a REV connector, does it...

Re: New Throttle / controller hookup question

The blue & black "brake" wires would be for e-brake. When shorted, the motor stops until the short is removed. If the switch on your brake lever tests open when released & short circuit when pulled, you could use it.

Re: Electrical issue with a 2015 Motorino Xpd 60v

Could be that the dc-dc output is noisy. If you can get hold of an analogue ( ie: one with a needle ) volt metre, connect it across the 12v output. See if it pulses or quivers. If you don't have or can't borrow an analogue Meter, a cheap AM radio held close to the output wires might pick up any nois...

Re: Belt drive fat bike frames?

G'day people's
I must be missing something here, but a belt being endless, how do you thread it around the chain stay? I saw a Mercedes branded commuter bike many years ago with a belt drive & a very clever CVT but I didn't pay attention as to how you got the bugger through the frame.

Hi TST & other folks. All I've tried is playing with the blue pot inside. Made a bit of difference to acceleration only.

G'day folks. I've had a look inside 1 of my spare controllers awhile ago with the same idea & I saw 2 issues with removing that circlip; First is that it already takes a big twist on the twist grip to get full throttle. Pulling the brass slide further would take half a turn at least. You'd want to f...

Re: E scoot newbie 1st post and already feels dumb

G'day mate.
Just thought of something & feel dumb for not remembering it sooner. Most motorbikes have a switch on the side stand with a kill switch type function. My 168 & neither of my two 4000e have them but the Aussie model may be different to the US models.

I've had a hub apart that was dragging. Not too hard but it's important to put a mark on the side plate & main body first so it goes back on in the same orientation or the brush timing will be wrong. The hard part is reinstalling the rear wheel without displacing the brake pads. Honestly though, if ...

TST, when you switch on, the sequence is 5 beeps, battery LEDs scroll up twice, OH LED flashes once then green batt LED only lights & all's good to go. Sound like the kill switch. Look for a blue connector with a red & a blue wire behind the front cover. Test with an ohm meter. Fechter, the EVT brus...
