Minor changes in the scooter...

I noticed that my watt meter was running down the battery pack too quickly. It ought to need 10-15 mA to run, but it's pulling down more like 150mA. I was running it direct to the battery buss previously. Now it gets power through the enable switch so it's off when the scooter isn't enabled.

I got a tire pressure monitoring system on ebay. It cost less than $50 and monitors 2 tires...assuming you have schraeder valves. It took no effort at all to fit it to the scooter. Thread on a locking nut, thread on the sensor, tighten the locking nut and you are done. I know it's going to add a little weight and make my wheels a little out of balance, but that's just a small wheel weight opposite the valve stem to fix that. As soon as I turned on the computer unit, it showed front and rear tire pressure. With a little button pressing, I had it set to Fahrenheit and had my high and low pressures set. There is also a setting for max tire temperature. Exceeding any of these 3 settings will set off the alarm function. The LCD screen flashes red and you hear a beeping sound. I simulated a tire problem by unscrewing a sensor and within a second or so, the unit was alarming. I had filled my tires on my air compressors regulated output which was set to 40 psi. I was glad to see that the sensors also were close to 40 psi. The sensors use a small lithium watch battery that is replaceable. They also go to sleep when the wheels are not turning. It takes like 5 minutes and they shut off. As soon as you start moving, they turn back on.

It came with a standard ring clamp for mounting to the handle bars, but mine are quite full so there was no place to mount the TPMS unit. I chose to cut off most of the clamping mechanism and use the original screw hole, a 6mm screw and a mirror mounting hole on the brake lever to mount it. It's out of the way and yet right where I can see it. The battery is fully charged. I'll see tomorrow...assuming the weather is cooperative how far I can go on a charge. The monitor unit has a screw mount on the bottom of it and locking nut to keep it mounted. The other end of the screw has a ball on it so that the whole thing can be tilted to your needs.

Image

As you can see my handle bars are quite crowded with stuff. Soon the app on my phone will replace the watt meter, speedo and the temp meter that is currently hidden. when I lock up the scooter somewhere, I'll need to grab the speedo, TPMS, phone, bike light and camera before I walk away.

I have been riding around with my phone in my pocket and been wanting to use the great app and telemetry module that Vadym has worked hard at creating. I finally got a quad lock mount for my phone so it can securely mount to the scooter.

Image

So far, I've been enabling the scooter via a rocker switch in this spot. I found a key switch that is compact and capable of several amps so I installed it. Of course if you remove those 4 screws, you can get to the back side of the switch easily enough. It's meant to keep the curious from flipping on the scooter, not be Fort Knox.

I got one of the Currie Flyer scooters included on a recent package deal, from skimming this thread and another thread with info from Dark Angel regarding the Currie stuff am I correct that the original internal controller will likely fail if run at 36V? The 2 SLA's in the thing we're pretty much totally discharged when I got the thing and after an attempt at charging them they only went up to about 19V.

I hooked up 2 Greenworks 18V NMH 3ah powertool batteries I had sitting around to it on a bench test and it ran real good at 36V, just ran it for maybe 20 seconds. After searching the forum I couldn't see any info on what the internal controllers were rated at and was hoping someone might know so I don't have to open the motor up to check.

I don't think I want to put an external 36V controller on this thing so my question is am I better off just running it at 24V or will the controller handle 36V, or are they a maybe you might get away with it type thing?

Thanks in advance to anyone who might know.

i have no idea. I got my Currie with a blown controller. Not that I cared, I wasn't going to use it anyway. But yeah...most likely it was designed for 24 volts and it will blow up at 36 volts, but I don't really know. Honestly, crack open the motor and bring the halls and phases out of the shell and run a real motor controller! The built in one is crap.
