This Bomber above now need a V-Boxx service or maybe a new V-Boxx. What's your advice to buy a new V-Boxx? Some time ago I read that Mammuth from Russia may sell it but I contacted them without any reply.
Or does Stealth bike sell replacements for V-Boxx?

I offered, but I think 12p was enough for this guy.

Is there any pictures of the cell layout and dimensions of that pack Alex? I'm fairly sure I know how you did it, as I did similar on my Fighter, but not quite sure how you got the length.

My next battery build will be top and bottom the same ie each of the top and bottom rows have 20S then when you fold the top over they cannot make an internal short even after any movement that may cause the insulating material to fail.
from there i'd add the other 2S ontop flat like your fighter pack for 22S 12P.

unfortunately by my calculations thats 35,000kms away!

On a great note i did 3000kms in 90 days with christmas holidays of 2 weeks with no riding in there too.
now 6500kms on the clock and showing 64 cycles on the battery, for a cycle (according to the CA) of 47kms.

Only charging to 90V and discharging to 80V, 80% of the time with average distance between charge of 32kms

I'm calling it 400 full cycles as per the datasheet for the LGMJ1 to ~80% remaining capcaity hence should do at least 600 given the lower max charge at 4.1V/cell and ~800-1000 or more before I no longer have enough capacity to goto work 1 day.

This gives us somewhere in the vicinity of 37-45,000kms pack life in my case.

Given this is 7+ years at 6000kms / year - choose your battery type and pack size VERY carefully as you'll live with it for a LONG time (and its not a cheap exercise).

My mistake - should have done 12P, should have built top and bottom layers the same ie 20-22S top and bottom so risk of short due to rubbing between the two layers eliminated.

22S with the stock controller produces 6300W under load hot off the charger with my pack, decreasing to 5000W when pack is down at 70V (unloaded) which is as low as i've needed to run it so far.

I think your choices are,

1. take it apart yourself, and order spare parts from Stealth.
2. send Stealth your VBoxx for repair
3. order a new VBoxx from Stealth for about us$1100+

That is the reason I built a 20s15p 30Q pack.....couldn’t go 22 with a MaxE other wise I probably would have.

Good advice.

I've torn mine down 3 times, its not that big of a deal as long as your detailed oriented.. you may be able to get spares from Stealth for your vboxx depending on whats wrong with it. You could always buy a new one and keep this as a spare parts box as well..
If you send it in to Stealth they send it to tawian for repair and the turnaround is at least 3-5 weeks

You'd think they could do an exchange to speed up the turnaround time...
Ask perhaps, let us know how you go.

How long before it failed? Big $$ part to fail, i guess that means you do some pedaling! :lol:

So I finally finished the rebuild of my Fighter and finally finished putting together all the footage for you all to witness. The editing took almost as long as the rebuild dealing with all that time-lapse as it crippled my PC to work on. :lol: :roll:

Enjoy!


I have a few more things to tidy up and replace on this bike (pedals, grips), then I'm probably going to be listing it for sale. As much as I will hate to see it go, I need the $$$ to fund another exciting project that may even lead to a patent application, prototypes and production run of something the likes that nobodies seen yet. All I'll say is that it is a kind of electric vehicle, but not an E-bike. :)

If anyone wants to get a jump on buying the Fighter flick me a PM with an offer...keeping in mind this is not like any other Fighter out there, so the offer would need to reflect that. :)

Grazie mille Rix. Fra poco smonterò il mio Vboxx seguendo i video sopra.
My Vboxx lost 1st, 2nd and 4th gear, the spur gear has a lot of play and I noticed a leak of grease from the bolt in the center of the spur gear.

If your spur gear is loose there is are 2 allen bolts on the top and bottom that sandwich the shaft in place, Check the side plates to see if there is any wear that may make the shaft loose (not top to bottom but left to right)...

Game on!

Pulled the 5403 apart to change the bearings and all the phase wires insulation was falling off.
Getting stealth to re-lace into a 19" moto rim so i can get away from the puncture headache
and lashed out on a UFO motor to get me going.

Not a cheap exercise but **Pay to play** never been a truer word spoken.

Yah 1ABV, I figured you would like the M403 Bridgestone off road. It works on dry, wet, mud sand and regular dirt. If you ride a lot of pavement though, the knobs will wear quicker than VRM 021 and Shinko SR241. And there lies the issue, trials tires offer all around good performance, but the knobby tires will offer better off road, and not nearly as well on road, as you have noted. BTW, Great write up/review.
So Rix, now that i'm dropping the coin to have the 5403 laced into a 19" rim any tyre suggestion for me?
99% of my riding is on the road and plan is to put a dirt tyre on the UFO as it apparently doesnt lend itself to a moto wheel build as unequal length spokes and odd locations for them vs evenly spaced

Anyone know the pole count for the UFO?
CA says I tapped out at 231km/hr lol.
Max amps up from normally 74-75 to 76.55A
While I was in there I beefed up a couple of traces on the earth side and main power + side where there was a gap between the input power DC wire and the wire that’s layed among the side of the board.
Cleaned it all up as it seems crystalyte weren’t too fussed about leaving heaps of flux all over the board.

Bike is now very noisy :(

Traps- motor sits further forward than the 5403 so either needs new torque plates or linish down the originals 5mm or so.

Need info re which are the temp sensor wires and where they go as couldn’t find this out in time for needing the bike to run today.

Will take it apart again when I find out where they go.

Incidentally it’s a UFO 5565 so .... sorry for those who think it’s too quick,,, the 5403 certainly feels quicker
EDIT :(speed on 22S 18650s stock crystalyte controller)

Try 23 and see if that brings your settings into check. I know the old 54xx motors were 12pole.

Roger that thanks Rix, headed over to the parents to collect = ~2hr train ride and 20min walk to the station this end and 5mins the other end for a 30min ride home :lol:

on another note, you had torque plates made for the QS 205, how do you find that motor over the 5403?

Thanks Rix,
23 for the pole count looks good for the Crystalyte UFO 5565 and lines up with GPS speed on the iphone.
done 55kms and used 25 out of ~32Ah available mix of cruising and belting it.
Not sure why anyone would ever want a 5580 or 55100 motor, the 5565 taps out at about 90km/hr on 22S and is very happy at 75-85km/hr. Edit - (guess you'd use these in little wheels)

Getting used to the noise and looks like i need another link in the chain despite the shorter torque plates as very difficult to make the wheel straight as runs out of adjustment in the slot (not sure why as appears the dropouts have enough slot to accommodate moving the wheel further forward but they dont want to budge.

Bummer as i don't have any half links laying around .

Climbs hills really well, much better than the 5403 , went up a hill that i could barely walk up, fell off a couple of times and it didnt moan and groan like the 5403 did with little fwd motion, just kept hauling along.

Don't have the tempsensor set up yet but after the 55kms even with a beer (or two) stop, upon arriving home its screaming hot to touch. Hoping this is the ferrofluid doing its job as despite the claims you don't need much, when i pulled the 5403 apart it had all but evaporated and turned into solid goo (whatever amount you get on the net in little syringe is clearly not enough for the 5403.)

It does roll better off-throttle which im surprised as on-line pics of the stator show the 5403 had a slanted / twisted stator the UFO doesnt have. (this is normally done to reduce cogging drag).

In all very happy with the upgrade (so far) and recommend it for others, as for the 11lbs alleged weight savings, they feel about the same to me to pick up and this would indicate less copper and more heating issues

I never ran the Qs205, I think that was BigBore, and originally Alex who went to the 205 on the Bomber.

So 5403 with the 19” rim, only took me 6 months,
Pretty excited actually unlaced the old motor last night, tempted to put holes in it, sand it back repowdercoat or better yet the satin/ gritty finish that’s on the UFO

I did run 5403, 5404, and 5405 along with TC4080, TC4065, TC3080 and a TC3065 all laced to 17, 18, and 19" Mc rims on my Bomber and Fighters, but no QS205.

Hi folks,
From where do others in Australia source batteries?
Doesn't seem easy nor cost effective.

I was thinking about making my next battery but after watching all the work you have to do CD, it makes me feel a lot better about just buying a battery.
