American Made Lithium Battery Packs

[Pure]

Or is it sales always increase this time of year?

This ^

It's income tax season!!

Simply changing ebike to electric bike changes the cities around, but yes the west coast leads the US.

We have American made 36V and 48V Lithium Manganese battery packs available for purchase on our website.

So if you need a high quality- lightweight lithium battery and don't want to deal with China, you can buy your packs from us..

You guys have great weather all year. Here it is seasonal.

[lester12483]

We are now fully stocked and can have your new battery delivered in 5-10 business days.

[lester12483]

You can use our 36 volt or 48 volt batteries to replace or upgrade your current battery. AllCell battery packs are higher quality and HALF the weight of Chinese made lithium Lifepo4 battery packs. Order online!

We used all cell phase change material in our club-assembled 18650 pack. It easily handled frequent bursts to 5C during the 1 hour race duration. We were using Panasonic cells. Thanks a lot, we placed first.

[lester12483]

I have noticed more and more people buying our packs. I dont know if its due to delays in China or what but we can get batteries to the customer in 1-2 weeks now.

[lester12483]

Thanks to everyone who posted and emailed me kind words about our batteries.

1) What is the specific PRECISE cell that Allcell uses for ebikes as of June 2012 ???

Please post discharge data for these cells...

2) Please show us by posting the cell voltage curve to end of discharge under various loads.

3) What is the calendar life of these cells ???

If Allcell can't produce this data, then I recommend not trusting this battery long-term. I would not buy one, nor would I recommend it. We need "real world" hard-data beyond the marketing hype of the thermal-compound stabilizer & positive comments from short term users.

If A123 can do this, then Allcell can too.

Here ya go, for a spec sheet:

http://www.premierbatteries.com.au/sm/lithium/Rechargeable/UR18650/UR18650%20(2.6Ah).pdf

You might say 'oh, that's a sanyo battery though!!'

http://gizmodo.com/5423240/panasonic-buys-sanyo-for-its-batteries

Panasonic bought Sanyo out.

Anyway, bad voltage sag on 2C as suspected. Put a 2C load on a fully charged ( 42v ) pack and it will dip all the way down to 38v. These are best ran at 1C or less ( just like any laptop cell pack )

Sanyo cuts off the cycle count in their spec sheet at 500, which should say something. That's at a 1C rate. Allcell advertises this pack as a 2C constant pack. I can't imagine how low the cycle life for these cells is at 2C usage. This is a number most lithium cell producers won't tell you because it is more often than not, rather awful.

Some formal tests would be nice, but the spec sheet tells us all we need to know. These packs are good if you have a real low power setup, or are willing to pay up for a larger pack just to feed a low-middle power setup. It is basically the lightest and smallest battery you can buy right now.

I agree with your analysis nep.

I wonder if Allcell will verify if this is the precise cell being used in 2012 for ebikes???

We're on Page 9 of this thread started in Jan.2011 & still don't know the precise cell spec info direct from Allcell. Bummer.

I love my allcell pack.. 1200 miles on it so far with zero issues.. I bought mine last september from ceb.

What controller do you use? What amps do you pull? On hills? Steep hills? Voltage sag is? What motor? Average distance traveled? Longer rides are? Which battery pack volts/amps? Thanks!

If it is the cells that we think are being used, then the calendar life does not look good, imo. Let's see how your battery performs after 2-3 years.

[lester12483]

They work great in any direct current (DC) ebikes. The packs are basic plug and play. They are small enough to fit in most battery compartments.

The fact the cell weight is lighter and battery size is more compact has me questioning about the real performance of these batteries vs well known chemistry such as A123. These battery cells are very suspect until we know the actual precise cell being used, so we can track down the data sheet on the cell. Until that happens, imo, buyer beware. I wouldn't risk my money on one until I knew that information upfront before buying.

It's a reasonable request too.

Can you get that information for us, since you are the most active seller on ES for this battery???

Thanks.

Hm, what is he more interested in.. educating people about the reality of this battery, or bumping his sales thread multiple times a week with non-info?

I'll let you take a guess based on the ignorance of what we posted

[Jeremy Harris]

This guy lester is just an annoying pushy salesman who bumps this thread in order to spam everyone here.

As for the cells and packs being "American made" you have to draw your own conclusions. I'm going to say that I think they may be just "American assembled", and that if you took one apart you'd find that the cells came from the Far East............................

If this is the case, then I think the claim in the title of this this thread should be challenged and maybe moderated out.

[Chalo]

I don't begrudge any vendor trying to get the word out about his e-bike battery here. But considering the audience, straight talk and technical data would probably work a lot better than vague hype and specious thread bumping.

Devries. I'm running an aotema kit with the battery. motor is rated at 800 watts but usually do 900-1kw. Controller is pulling 25amps. I've noticed the voltage sags a little really close to when the battery is depleted. I live on the fourth floor in apartment building and went with the lightest 48 volt battery I could find.

Jeremy Harris u should sit down and breathe my friend . Lester's posting in the correct thread. Who cares how often he posts. You could do the same if you had something to sell.

[Jeremy Harris]

Jeremy Harris u should chill. Lester's posting in the correct thread. Who cares how often he posts. You could do the same if you had something to sell.

But is he being wholly honest in the title? Are these cells "American Made"? I suspect they come from the Far East, maybe even China, like the majority of the cells we use. At best this pack might be assembled in the USA, but then that could be said about the packs of any of the members here who assemble packs. Where I live this thread title might be breaking the law (if the cells do indeed come from the Far East, as I suspect) by misrepresenting a product in advertising with intent to deceive.

I have no problem with an advert here at all, if it gives an honest description and truthful technical information, but the constant bumping of this thread just to get it to the top on the new posts page and put it in people's faces all the time, plus the refusal to give any decent technical information on the cells, is a pain, IMHO.

Tesla cars are made not too far from where I live. Think about it..
They use foreign components and still label it made in the United States because it is. Building tesla cars employs Americans just like building ceb's batteries. There's really no way around the foreign component thing.

The difference here is in how people interpret "Made" (with the deliberate capitalisation) when they read an advert. With a car, then they will know where in the world the manufacturer is, and most will know that cars are assembled from parts manufactured all over the world. The reputation of the manufacturer in its base country is usually known and car manufacturers don't try and hide the true origin of the parts that they use. Some countries, (notably the USA in my personal experience with defence related products), have rules about it - the USA often insists that a significant proportion of a product has to be actually manufactured in the USA (meaning manufactured from raw materials in a US factory) if it is to carry a "Made in the USA" label.

Lester seems to me to be trying to pass off his cells as being "American Made" as an indication of some form of quality assurance to customers in the USA, when in reality the pack is only wired up and fitted to a housing in that country, I believe. The critical components in the battery pack in terms of quality, performance and longevity, are the cells, that most probably come from the Far East, an area that Lester seems keen to be oddly critical of in his bumps on this thread. If the cells are indeed the Sanyo/Panasonic 18650 cells mentioned earlier, then the chances are they are actually made in Suzhou, China, or maybe Japan if they are old cells, made before the major production switch this year.
