Selling my VX-1 NiMh bike in San Diego

Not sure what year it is and I need to get the VIN but I'm posting this now to see if there is any interest on this Forum. Vectrix gave me this bike to use while the factory fixed my Li bike. My Vectrix contact said they put in a used NiMh pack although the rear fenders say VX-1 Li+. It runs and charges but only gets a couple of bars above half-way. Odometer shows about 1020 miles. It is it perfect shape and would probably make an ideal Li conversion candidate. If you know of anyone interested, please PM me or email at Thanks!

Ideas on how to fix the dreaded....RED FLASHING lights of battery and sensor lights

Hi all hope you guys are all well .?
i have been stuck out in the cold british weather and raining bad!!!!
awating to be collectrd by truck.n traler to take me home the..... dreaded red lights came on just b4 i left to go to town battery and sensor lights :-(
so when i came to pick scooter up all dash lights on but scooter wouldnt start at all ..
is there a simple way of fixing these probblems that seem to blyt a lot of VECTRIX owners my scooter has 13,500 miles aprox on it
and around these miles they seem to have the odd gremlings i think...
so if you han help in any way please feel free to advise me on simplest and cheapest way to fix ..

i have been away for a wile been busy fitted log burner/stove and also had 3.6Kwh system fitted and also a 32amp car charger fitted to home
but 2012 model wont accsept yet 32amp ?? i wonder if theres a upgrade
for hopfully soon ?????? a 21012 model nissan leaf white would be first choice or second sky blue 0 to 15,000 miles would ok great condition
so looking at moment my partner not overley convinced as yet , so i will keep looking for a good second hander????

thanks guys

YAVLiC - Fitting the Li battery 2

I am trying to figure out how to fit the battery. The original plan was to put 32 cells arranged as 2 rows of 16 in the bottom of the battery compartment. However, they don't fit.
At the rear, welding lugs from the frame's rear casting are protruding. I am prepared to grind some of that away to make the cells fit side by side.

The interference at the front is more problematic:
I am not going to attack the frame with a big hammer or a hydraulic jack and I won't grind away material from the frame's tubing.

Well, adversity is the mother of all innovation... So now I will be able to fit 33 cells instead of 32! See:

The whole pack will probably be arranged like this:

YAVLiC - Fitting the Li battery

Received the battery. 42 CALB CA66Fi cells, 66Ah. 32 of them go into the battery compartment standing up as 2 rows of 16 and the remaining 10 will be stacked flat on top, most of them where the impellers used to be. Unfortunately the supplier forgot to send the interconnects. Next week then...

Battery cooling

I have satisfied myself that forced cooling will no be necessary with the cells I bought. As a contingency however, I have a plan B which will use conduction instead of forced convection. 2mm aluminium sheets between the cells would serve as the heat conductors. They would be thermally coupled to the bottom of the battery compartment. For the cells stacked horizontally, I would have to come up with a heatsink – maybe the plastic sides of the battery compartment could be replaced with aluminium sheet...

Battery mechanical fitting

I could not fit the cells side by side where the frame welds are. Some of the protruding welds will therefore have to be ground down by about 1 mm. Also interfering is the bracket for the rear temperature monitoring board and a rivet in the front center of the battery compartment. While I am at it, the big ventilation holes will also need to be covered – this will stop the battery from getting a shower when I ride in the rain.

YAVLiC - Got the bike now what?

After having been convinced by Matt Lacey's Li conversion videos that a Li conversion is quite managable, I started looking for a 2nd hand VX1.

By good fortune, I ended up with a VX1 from the former Australian Vectrix importer and distributor. The bike is ex-demo/showroom and I have been told it has done less than 500km. It has a few marks and the chrome plated surfaces have brown corrosion spots. The battery could find a new application as a zero-volt reference if it were not so heavy, and since the plan always was to convert to Lithium, I did not even attempt to revive it.

My choice was to go for the largest capacity battery possible. Partly because I don't want to have to worry about making it to the next charging point and partly because the disacharge capability of the battery is proportional to the capacity. At the same discharge current, a larger capacity battery will be stressed less.

A local distributor still had stock of CALB 66Ah cells so I ordered 42 of them. As of July 2013. CALB does not make any 66Ah cells, only the 60Ah ones. The datasheet states a max discharge current of 2*C (132A) so a peak discharge with up to 200A for a few seconds should be well within the battery's capability. Internal resistance (Ri) is quoted as < 1 mOhm. At that Ri, drawing 50A would dissipate 2.5W of heat per cell or 105W for the entire pack, at 100A that would rise to 10W and 420W respectively. Average power dissipation of the battery will probably be closer to 105W than to 420W, depending on how I use the bike. In any case, with the LiFePO4 cells, I am not too concerned about battery cooling and the 2 battery compartment impellers will be permanently removed to make room for more cells.

Vectrix Regen Throttle Setting Instructions (With Pictures)

Re-Setting the Regen Throttle - Vectrix dealer definitely NOT required!
(This is mostly a re-hash of Mik's post of Sunday, 10/05/2008 @ 21:00)

Tools Needed…

(Possibly a pair of grips or similar with 25-30mm (1" to 1.5") jaw capacity - see below)
2mm Allen key or hex driver (Allen key best)
6-8mm (1/4" - 3/8") flat screwdriver

It is worth noting that what we are doing here is setting the point on the throttle at which regen occurs rather than calibrating the throttle in general (according to the service manual). This can be more accurately checked and set using the Vectrix diagnostic program running on a PC (see the Service Manual for this procedure).

To begin...
Unscrew the stainless steel handlebar end cap from the end of the throttle grip.
This should(!) come off by hand, turning ACW as you look at it but if not use a pair of grips (with protection to avoid marking the end cap).
This will reveal the magnet holder which is a white, threaded, plastic plug with a flat screwdriver groove cut in it (A). Somewhere in the adjuster plug is the locking set screw (B - with Allen key inserted).

Using the 2mm Allen key, loosen the set screw (B). It will only need a 1/4 turn or so to loosen it sufficiently. Ideally it should not be completely loose to make adjusting the magnet holder easier ie it doesn't wobble about and move on its own as you rotate it.

Turn Vectrix on.

Switch the 'kill switch' on the right handlebar to 'off'.

Pull the left brake lever - the speedo will show 43kph if the setting is correct.

Additionally, pulling the right brake lever whilst the left brake lever is already pulled will make the speedo show the correct setting position of 43kph irrespective of the actual setting. This allows you to see exactly where the needle should be pointing when correctly set.

Insert the flat-bladed screwdriver into the magnet holder groove...
... and rotate the magnet holder by turning it CW or ACW in small increments until speedo shows 43kph when left brake alone is being pulled.

Check you have it correctly set by pulling the RH brake lever in addition to the LH. The needle should not move. If it does, adjust the magnet holder in the appropriate direction until you can apply the RH brake lever without the the needle moving.

Tighten the set screw with the Allen key. Do not over tighten it! It needs only about the same twisting force as the throttle does to accelerate.

Replace the handlebar end cap.

I don't know what the maximum and minimum limits of throttle as indicated on the speedo should be. Does anyone else?

Good news bad news you decide??

hi all wel what can i say.. had probblems with scooter not charging and i/e red lights keeps on sensor and battery aswell.

1 scooter wooden t charge up so left scooter turnd off lights / dash keeped on with caNbus showing..
2 so decided to use my other scooter and change the insurance over and also put vectrix on sorn that is letting the tax office no that the scooter will not be used and there for the tax 11 months will be void all done with little charge

3 well comming to the scooter yestaday i had let the scooter cool down for aprox 4/5 day and guess what.

4 it proved me wrong all worked well so today spent most of the morning chasing round the tax/ vehicle licence office and not forgetting the insurance company all done and changed over.

5 well now is where is its getting silly came to use my pride n joy vectrix yep you geussed it the RED LIGHTS FLASHING SENSOR AND BATTERY TOO....

6 so did normal start up and off to the post office all goo be lights still flashing but i did not use regen at all gonna see how i go???????

7 well after posting letters restated scooter the red lights never come back on ..????? well as yet

8 so i am guessing that if i don't use regen and also take it very easy with throttle and try not to get to much. heat in the battery pack this may help???

9 as i am guessing that the is a odd battery over heated/ maybe even swollen also may have faulty sensor or the battery is making the sensor light up ?

10 i know regen can heat the pack up but these scooter must / will have been tested in the most extreems of wather situations am shure as in England is pritty cool most of the year round

11 and if you was to tatall the avrage weather all year round wouldent be far off 15c to 20c for all year round

hope this is food for thought and i wonder if anyone has had same situation or same hapend to them .?

please ad to thread as this is the only way we sort these probblems out for old and new customers / owners of these great machines
thanks kev

please please please any help is much aprecated to get her back on the road thanks kevin smith

aka eco kev.

Damaged panels replaced

Colin Webster has just helped me replace some panels on my Vectrix. I would be really stuck without the fantastic support I get from Colin ( It would be great if the powers that be at Vectrix similarly support folks like Colin.
