I checked into getting the cells to Canada from the USA. I was told they could be just dropped in the mail (but I don't think the lady at Canada Post knew what she was talking about) or they can be delivered by UPS with no extra cost, paperwork, or markings. That is for two cells.

DocD, I sent you a PM. Your reply is awaited.

Hi,
Just one more time :thumbsup: still hopefull, a nice CPF member might come with some info to my last post and even better pick up the USA side of things,
going to try for a few more days if no one comes forward ? well,
I'm sad to say going to put this back to bed and let someone else have a go, i'm a bit sad over this as i and plasmaman put quite a bit of time and effort in :sigh:
but thanks to all and the posted and info, hopefully it might happen :twothumbs
cheers DocD

Hi guys,

Sorry that the bulk purchase didn't work out. Could someone please post the manufacturer this thread was based around? I'd be quite interested in buying 50 units myself as I want to make up a 20s2p battery pack for an ebike.

I know that for the purchase of smaller amounts people here are interested in having a regular user of the forum organise it as there is obviously trust issues with prepaying for a bunch of expensive batteries. I'm not sure if there would be much interest but I'm happy to try an order of 100 and cough up the total $$ myself if there's enough people willing to buy some from me afterwards, though because it's a risk and a fair bit of money to dish out I'd ask for a token profit on each unit, say a max of AUD$5 each on top of cost.

I'm aware that it's not the 'feeling' of these forums to make a profit off each other, though as I'd be dishing out a lot of $$ to start with, plus hassle of lots of time organising P+H for each small sale afterwards I think it's understandable as I might not be getting my money back if I don't sell the ones I don't need.

Even if this is not something anyone's interested in doing, I'd still LOVE to find out the 'company' that's referred to on these posts. If anyone could help please post some info, (or PM me if you'd prefer)

Thanks a lot!!!

Regards,

Marcin

After all this time I would still be interested in a few cells if you can get a group buy together. I don't think adding $5 to each cell would be bad if your forking out the cash up front.

marcinebike, I'd still be interested and should actually have funds soon. I hope you get the information you need and enough interest to supply the rest of us. Thanks for offering to run the group buy.

Put me down for 4 cells depending on final price and availability of funds at that time.

Oh fantastic!

Thanks for the info. Judging by the enthusiasm early on, I'll take the risk and order 100. I'm sure if it doesn't get all sold straight away, I'm tipping eventually I'll get my money back for the 50 I don't need.

I'll see if I can call them today.

I'm from Perth Australia, and so long as I can still get them, I'll get the lot delivered to me. So once they're here I'll work out a per cost amount which factors in postage to me etc. Then you guys can send me that amount + postage from me to you + AUD$ 5, which I think is reasonable as I'm likely to be spending a fair bit of time and effort making lots of small packing and posting etc.

Thanks everyone I'll keep you all posted!

I would be interested in 7...( i did post in this thread years ago, but it never went ahead) but they would have to be D size or only a few mm more or its no good to me.

(Also Does anybody know what the nominal and end voltages of these are? / I want to run a regulator)

I'd be in for 7 or more.

BTW I'm in the UK so if you need a hand let me know. ( I think they are made in the UK)
I can ship stuff, It may help in the long run to have a UK shipper, and I'm actually doing the dangerous goods by air course in a few weeks..:tinfoil:

From what I recall you can ship these cells but only in the light they are to be used in so i will have to get my 6 D mag out as a shipping mule :devil: ( Unless we go with shipping a la slow boat from China.

progress, sent an enquiry email and got a response from a bloke named Vincent:

Dear Marcin
Thank you for the enquiry.
Please use the following information regarding price and availability.
Both types HC and MMO are the same price. For quantities of 50 to 100 the cells would be £28 each.
Lead time 8 - 12 weeks although we should be able to reduce this. Ex works our factory in the UK.
This does not include any VAT export / import duty.
You can download a data sheet from our site www.abslpower.com
I hope this is sufficient information for you at this time.


--
so i've compared these to some other batteries for my ebike and although the lifepo4's have a better current rating I'm all about weight/size energy density for this project, and these are about triple the price (not including shipping) but nearly double the energy density of my 'second choice' option of lifepo4's. my only concern on the datasheet is the cycle life degrades MUCH faster than with the LiFePO4's.
--
However when the capacity drops all the way to 50% (over 1000cycles), the energy density these can store will be the same as the LiFePO4's i was considering. So that's pretty impressive in my books, as I wont be using the ebike on a daily basis, (maybe moreso a weekly basis), hence I'm guessing that natural ageing will impact them more than actual cycling.. lol
--
Another positive about using these over the LiFePO4's is the shape. They are very similar size to a "D" cell, with the blob on one end so that they can be stacked. -- good for you guys but also great for me as the main part of my project is to conceal the batteries in the frame of the bike (a fairly thick frame though), hence the ability to remove the batteries and charge them (with balancing), is preferrable for me than permanent batteries with a terminal at each point so as to be able to balance them. plus just generally replacing batteries / battery maintenance etc will be quicker and easier.
--
either way I've checked and double checked everything with my finances and will be making payment to the company on Monday 12th July.

oh I nearly forgot:

Although I see the irony in having batteries sent from a factory in the uk, to australia, just to be sent back to the uk; I'd still rather do it that way.

Previous attempts at getting these batteries started to get really complex etc, and I'd like to keep it rather simple where they all get delivered to me then I'll distribute the one's I don't need.

Also, with previous group buy attempts everyone had to prepay and someone had to be selected to organise it all etc, and I suppose people were willing to throw a few hundred at something with the trust that it's gonna be ok, etc.

As this is gonna cost me a few grand, I don't want to be in the position where something is lost, etc. with me losing out on some bigger money.

By having them all delivered to me first I'm avoiding being in a position where I can blame anyone for anything, and I'd feel much more comfortable with it that way. I hope I'm not offending anyone by this, and I greatly appreciate the offers of help from the uk, and at the same time graciously decline them.

ps. Oh by the way, I've read in a datasheet that they do have to be labeled 'class 9 hazardous' for transport, but can be transported via sea with nothing special other than a label stating that it's hazardous.

Also, as they will come in one massive pack to me, the shipping should be pretty small compared to the purchase price anyway, but if you guys in the uk wanna save on postage me to you, once they're here if you guys wanna organise someone in the uk to receive a bunch of them at one adress (if you live nearby etc), I don't mind so that way you guys can save on postage etc.

anyhow, getting closer to the 12th july I will be contacting them to get order form etc, and will keep you guys posted about the progress... seems like a bit of 'hurry up and wait' thing, as after the order is made it's a lead time of 8-12weeks.

so now we play the waiting game.... :whistle:

Hi, given the investment you are proposing to make, it might be a good idea to post the specifications and safety features of the cells you are planning to work with.

It would be really sad to see you get stuck with a large investment into unprotected D size Li cells. There are several "layers" of protection needed to safely use Li Ion cells, and a mfg's tend to be rather liberal with the term "protected".

Consider to take a look at AW's sales thread and read through the information about the various protections in them. A "D" size Li cell needs to be respected - a lot.

edit - are these the models with the "K2" protection circuit? Is this the cell ? http://www.abslpower.com/pdfs/v3ICR36550HC.pdf or is it the mixed oxide INR type?

edit 2 - dumb question. How do you charge up a 20S2P pack? I didn't realize such a charger even existed.

Great to see someone picking up on these - good luck with the GB project!
I have been very happy with the 7.5ah D cells I purchased from AGM, but just to say that my cells are flat top and need a contact blob added if used in series.
