At first, I thought the P7 may be my new favorite Stealth bike because It was new to me. Not the case though. Its my favorite Stealth Bike. It wont touch the Bomber and Fighter in terms of performance, but it beats them in the handling department due to being alot lighter. What I don't understand is, it also works better than my Beta. My beta is a bit faster acceleration wise, however, it doesn't handle quite as good as the p7 either. The suntour fork is just plain awesome. I ran alot of forks in my day, I put this at the top of both single and dual crown forks in terms of stock performance. The DNM rear airshock works just as good as the Rockshox air shock I have on the Beta. In summary, Stealth nailed it with the P7.
Yeah I like this frame a lot and with a single crown fork it is a totally different machine, love it!

Everytime i see you your Beta Allex, I think what an awesome build. My builds can't touch the cleanliness of your builds, or match the power to weight ratio. I got another Alpha frame in, of course its Army green, sticking with the "Rix Theme". Still no sure which way I will go with it, but one thing is for sure, it will be a long range machine.

Thx, Rick, Beta is the best looking frame out there among others, def. my fav.
Yeah, to get the wiring clean I need to spend just as much time with it as to build the whole bike up!

I am not surprised. I built the Beta and Alpha frames into rollers, which included lacing up the 4504 on the Alpha in one very long evening. Then the hard part started with making everything work, splicing wires, stuff like that. Took me way way longer.

Cowardlyduck"That will be a long range pack for sure. Do you have a battery spot welder? How are you wiring it up? Are you going to run a BMS?
Yeah, long range and about the same weight as stock also. :mrgreen:
I don't have a spot welder myself, but there's a number of fellow ES members around these parts who are very kind and have/will lend me their JP spot welder.
I'm not a fan of Battery Murdering Systems. :P I have a number of little 6S balance boards I'm playing around with atm, so I might hook those up to the balance leads, but for the most part I will just monitor cell levels periodically myself. This has worked well for me for a long time now, so I don't see a reason to change.
To get an idea of how I will build it, watch my video on the build of the 18650 pack I recently made for my recumbent
My only concern for the Fighter pack is if the realised size exceeds the anticipated size. That's why I plan on taking my time, and making sure it is as tight and compact as possible, while remaining safe, well padded and rigid.

Cheers
Hey Ducky, I can't remember, but did you originally run your Crystalyte H40xx with the Adaptto mini E on your Fighter? I only ask because I have an Alpha frame and am contemplating my next build which will be with another Adaptto Controller and possibly the H40xx or the new H55XX. We all know the TCxx/TC40xx series is not compatible, but I can't remember if the H series is or not.

Yeah, the HS4080 (and 4060) work great with the Adaptto.
I personally won't be buying another motor that isn't using 0.35 laminations or less, but the HS40 does work well enough.
The only issue I had was running the 4T 4080 with my Mini-E would occasionally cause the controller to overheat. It much prefers the 5T of my Leaf motor, but if you were using a Midi-E or Max-E you would be fine.

Yah, thats all part of that whole inductance load thing. So it appears the H series is compatible with the adaptto then. As far as lam thickness goes, Crystalyte is now reporting all their motors are .035. http://crystalyte.com/

Check it out.

Thanks Rix!
I did not know they were making them like that now...that makes it a challenging choice for my Alpha build for sure. That H5580 is looking pretty good. :)

Yah tell me about it! On top of this, I can't make any definitive plans until I know of Adaptto will be back. I have it from a reliable source adaptto is still doing warranty/service work, but no word on production. I did check the website. I noted they finally updated the MAX E DC rating from 140 amps to 160 amps. Maybe this is a good sign they are going to be coming out with an updated batch of controllers. :?

On the weekend I caught up with a mate who has just had his B52 upgraded by Stealth in Melbourne. They supplied him a bigger pack and motor, and man does it rip. Only slight downside was some extra decibels from the motor and the regen took longer to start working (not sure why.) After the loop we often ride my battery life was at 17% where his was at 53%. Normally we would be very close in usage. Sweet upgrade even if the price is substantial.

Yah, the new Bomber pack is a 22s unit and it packs a punch. I got one sitting in the shop and have ran it against an older pack, its way better. Stealth has and will always be evolving. Stealth is heavy into R&D. I can't disclose any details, but believe me when I say this, if someone has thought of it, Stealth more than likely has a prototype of it.

At 6.2Kw it’s a noticeable improvement. Top speed limited at 95kph I was told, although more of a torque upgrade than speed. I am saving my pennies for the same works as my pack has done over 700 cycles and the bike has over 20,000 kms. In saying this I have seen no losses so not sure when it will come. I have been very happy with the reliability of my bomber.

Hi White Knight,
I am wondering how old your battery is and if it has had any extended non-use periods?
I couldn't help but note you have 700 cycles, 20,000km and you haven't noticed any loss.
This seems extraordinary when compared to my experience; similar cycles, half the ks and 1/4 range. My battery is four years old now.
Cheers

It would appear you and I have had the same luck with the original new generation pouch cell battery pack made for the Bomber. Mine is tired, its almost 6 years old, and has some where between 10,000 and 16,000 miles on it. I don't know for sure as my Dad was messing with the CA V2.25 and has manually reset the entire system, twice now.

My original Fighter battery did end up being ok, but only after it was replaced in 2012, then repaired (cells replaced) under warranty 3 or 4 times.
I ended up putting about 500 cycles on it and over 15000km. In the end it really started having issues pulling more than 50A and would only give 13-15AH if ridden hard. It would still work fine at lower power levels though, and even after the 500 cycle mark I was able to get 17AH out of it if I limited max amps to around 35.

Now I've just sold it for $300 to a guy who is going to use it on a drift trike. :mrgreen:

My battery is two and a half years old and has been used consistently in this time at least every three or four days. I drain it to 20% most rides and the bike is kept in fairly constant temperatures. I am aiming for 1000 cycles see how we go.

Hey I hope so. Rix a friend offered to give me a spare bomber pack in the same condition as mine. As I am lazy to keep swapping the packs to keep it in use, is it worth storing the pack fully charged and will it keep good for some time? Your expertise would be appreciated. Cheers.

When storing the battery for a long time, you should only charge it to 70%.

Scrambler said it with 70% for storage. I think think this would mean with the older Bomber LIFpo4 cells, figure on 3.3-3.4 volts per cell at 24 cells. Lifepo4 cells are fully charged at 3.65 volts per cell. So charge to around 79-80 volts. Now the cells will act a little different than lithium Ion because with the older pack, the HVC shuts down around 87.6 volts, then after 24-48 hours or so, the battery's surface voltages settles between 79.9 volts to 80.1 volts. So when you charge it to 79-80 volts, you will see the voltage drop after a day or so. Don't worry about this. That said, if you can use the battery a little (1-2 miles and recharge once a month to about 80 volts, the battery should store for a year or better.
