Re: KT-LCD3 Button Question/Help

So with this "setup" you described you can only drive 25km/h once the button is pushed (on position)? And if you press the button again (off position) you can only drive 25km/h too? Or do you mean, when you press the button (display off) = no limit and when you press it again (display on) = 25km/h ...

Re: KT-LCD3 Button Question/Help

In the videos he said, that if you press the button the display turns off but you can still drive. (25km/h) If you press the button again, the display turns on again, but it's still locked at 25km/h. Ah, if that's what he's doing, then it means the LCD is setup to limit speed, but that the controll...

Re: Looking for a chromoly rear rack, any suggestions?

THat "150kg" rack *might* support that much weight if you carefully stack up weights on the bare rack secured to something with hardware other than what it comes with to attach to the bike. But if you put it on a bike and put that weight on it, then ride down the road, I suspect that weird curved bi...

Re: KT-LCD3 Button Question/Help

What does the guy that made the video say when you ask? (or is he unwilling to discuss it?)


Most likely he is using a setting in the system itself to give two modes, and the button just chooses between them.

_If_ it was only bent, then the heat wouldn't likely weaken it because you're not heating it beyond a critical temperature, but if it has cracks already, it's a lost cause except possibly for welding. Even then, with your equipment - a wire feed mig, I'm guessing? - I wouldn't expect it to work out...

Although I've read most of this fascinating thread over time can you refresh us on what type of rim you're using on the back?

But I have had cable brakes snap the cable at the pinch bolt or at the lever from flexing and fraying.. That isn't very fixable in the field either, unless one is carrying a spare brake cable. It is if you have a way to cut the housing down a bit ("leatherman" type tool has enough stuff on it to do...

Re: Variable Regeneration Voltage Questions.

Your controller is what determines if you get variable (proportional) regen, and how it works. So you have to look at the manual (if any) for your specific controller (probably available on the Grin site) to see: --if it has proportional regen --how it's controlled. Most of the ones I've seen use th...

Those are some bad-ass spokes you got there. A lesser-spoked wheel wouldn't have made it at all! What are they, 4MM in diameter?! :shock: Or do they only look larger than "normal" in the photos? Those are actually just 13g Sapim spokes from Grin. But they are pretty good, since none of them failed ...

Re: Help Please, Bike cutting Out

If you have a meter that can read milliamps, you can put it in series with that cell's balance lead and see if there's any current flow when the cell has voltage on it that's below the HVC point--if there is, the channel is stuck on, and is draining that cell.

Re: Would you charge a 4s LiFePo with a "15V" wall wart (intended for charging a 12V SLA)?

That's a much more complex regulator system than I've seen on any of the SLA-powered devices I've worked on so far (except UPS units)--most of them depend on the battery smoothing stuff out. It makes it more likely it's got some safety cutoffs, but whether they are appropriate for anything but SLA m...

In that scenario, would the battery still appear to charge as normal (which it did) ? Generaly, yes, as the fuse is usually only in the discharge connector, and the charge connector is usually separate. Not that it matters in this case, as the disconnect was the problem. :) Regarding range, 10Ah is...

The IR from the pole camera is pretty bright, though I'd get better coverage if I had the IR lights under the trees separate from the camera, so it doesn't light up the trees and "blind" the camera to anything past them.

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

It has the ability to connect to an analogue ammeter (the ones with the needle). However, it uses the same pin as the thermistor so you can only use one or the other. The current limit is programmable though so I guess setting that to a reasonable value and using the pin for a thermistor makes the ...

Re: New "TSDZ2 Torque Sensor Central Motor"

If the jam caused an overcurrent at the battery from too much controller current draw, you might just have a blown fuse in the battery.
