Anyone tried this LiFePO battery pack from CYCLONE Taiwan?

Hello,

I've started the process and will soon be giving up my car for an ebike. I've got the "donor" bike (a Townie 8 with 700c wheels). I'm going to buy the Crystalyte Phoenix to run at 48v, but I DON'T want to use SLA or NiMh. So my one hurdle is the darn battery.

I came across this:

http://www.cyclone-tw.com/lithium.htm

They have a 10Ah 24V LiFePO4 Battery including: charger and shipping for like $500. I'd have to wire them together in series? I really don't know squat about electric doodads and such, but I'm good at following directions.

Anyhow, the site claims a 2 to 3 thousand recharge life.

Any good?

I was thinking about building a pack from the Dewalt a123's but it just looks too complicated for me. There isn't anyone selling 48v (ish) a123 packs, are there?

Thanks!

They also offer LiFEPO4 here: http://www.falconev.com/batteries.html but I have no personal experience with them.

Batteryspace is selling LiFEPO4 now: http://www.batteryspace.com/index.asp?PageAction=VIEWCATS&Category=1072

LiFEPO4 appears to be a rapidly emerging technology and will likely push other lithium technologies out of the market such as lithium polymer. This means prices are likely to drop. Just my two cents.

Sorry I have no experience with the company you posted. I don't have any experience with LiFEPO4 either so I can't say if any of their claims really are substantial.

I'm interested in any testing or data they may have so I sent them an email to the US email listed here

I may be interested in your LiFEPO4 batteries. Can you please send me any information you may have on them such as spec sheets or testing information?

Thanks,
Andrew

I'll also contact falconev

Hi Andrew,

Thanks. I'm sure you'll let us know what you find out.

I'd love to get a nice 48v 20ah setup for my yet to be bought 35+ mph hub motor. If the batteries were ready I'd buy it today.

Yes, but don't have any real test results yet.

Re: Anyone tried this LiFePO battery pack from CYCLONE Taiwan?

If your motor is 48v, 72v (or 24 x 3...etc.) You will have to put your batteries in series - however you want the total amount to safely match your motor. Do not under power an electric motor! Make the total voltage of batteries the same as motor. Another thing to take into account, make sure if your motor is 500w or more - drawing 35ah for example, have your total battery amp/hr match your motor's total amp draw or have it higher to reduce stress on batteries, increase life, and eliminate overheating dangers. The most accurate way to find out what your motor draws in total amps, have a matching controller, and go by its max. Current input. That's what your batteries should at least match. If you have a motor that's 24v you may want to put your batteries in parallel and series. 2 set's in parallel and in series with the other 2. This will allow 2 x 12v batteries to become 24v. And lets say it's 20ah, by having them in parallel also, you will double the amp hours to 40. On a 24vdc motor that draws 500w, you need 4 sealed lead acid batteries, (all minimum 12ah) 2 in parallel with the 2 pairs in series. This will total: 24v at 24ah if you've done it right. That is the minimum safe amount for 24v 500w max motors. The one dilemma most people face one way or another is the battery. SLA AGM batteries are the best choice for cost, they're downfall is in weight. To properly power a 24v 500w motor you'll most likely need 4 to distribute the weight efficiently. 2 SLA batteries to power that will require larger batteries thus giving less options for mounting simply because they're bigger (when less of them, to make up for the ah) and heavier in one spot. One the other hand, the best choice "overall" is the lithium ion phosphate battery. In many aspects these batteries rate "top" and you'll pay for it. The optimal battery setup for these would be 2 x 12ah at 24v (2 batteries) presently the cost is 450$ each. 1 will not be enough to prove anything interesting. So for batteries, in conclusion go small/light for $1000+ or large/heavy for around 300$ at the expense of further rigging. For me, it is much more worth saving 700$ and rigging up batteries to get out more capacity for your money. If I had the money however, i would use 5 lithium iron batteries in parallel at 20ah totaling 100 ah. That would make a very performing e-bike. I have invented my own high-powered e-bike, which is why i have extensive knowledge on these things. It is very impressive and the first of its kind. Not on the market, and is my assembled kit. http://www.youtube.com/profile?user=luc59457

Re: Anyone tried this LiFePO battery pack from CYCLONE Taiwan?

I got the LiFePo 24V, 20Ah pack from Cyclone-TW about a week ago. I also got their 500W motor kit. Paco, the contact person there was responsive to my email questions, and everything was packaged well, and arrived intact. I have not installed it on the donor bike (Specialized Crossroads) yet, but when I get that done and some miles on the bike, I'll post a report.

Re: Anyone tried this LiFePO battery pack from CYCLONE Taiwan?

I have a Specialized Crossroads and am wondering if the kit from cyclone will fit, looks very close.

I have looked at their batteries as well but the site says "The 500 watt motor performs best when coupled with our high performance 24v 24Ahr" I am wondering if this is a typo or just old information. I found this on the USA site not Taiwan. I would love to put the 500 watt on my Specialized Crossroads let me know how it goes and let us know how the batteries preform.

Thanks,
Chas S.

Re: Anyone tried this LiFePO battery pack from CYCLONE Taiwan?

Th technician/owner of the bike shop in Healdsburg was very helpful, and thought the kit would work on the Crossroads. The battery pack IS the 20Ah 24V, not 24Ah.

I received the 500W motor kit with 24V, 20Ah LiFepo battery pack from Cyclone Taiwan about 10 days after ordering. Paco, the contact person, was responsive to my inquiries, (even asking why I ordered the speed limiter, so we canceled it to save a few bucks.) All the parts arrived unmolested. I will report on how it all works later.

After visiting many bike shops with an 82 mm ruler in my pocket, (82 mm is the minimum space needed between the bb and rear tire for the motor mount to fit), and test riding a few bikes, I settled on the Specialized Crossroads. Not perfect in every respect for this conversion, but I am hoping it will work well. I left the Cyclone bb spindle, cranks and chain ring with the bike shop to swap out the stock parts. Only $10 for the new bb without spindle, and $25 for installation. (The Cyclone spindle is designed for the older style “cup-cone” bottom bracket, thus the stock Specialized sealed type would not work.

I’ll pick up the bike in a couple weeks, install the motor and battery, and complete this report with a test ride.
