Hi All,
In early December we will be delivering our first lot of cells and packs.
I will also have a number of cells and packs for testing. Although our cells are undergoing independent testing in the US, by an number of institutions, I would like to do the same here in the UK.
And this is the point of my post, I would like to ask the community who they feel would be the best people to do this. I am looking for a person or instituion who has a proven track record for fair and accurate testing, someone who's word is respected and are able to make their results publically know.
Any and all suggestions would be greatly appreciated.
Kind regards,
Ian

Id think a good place to start might be by giving Denis Doerffel @ reap systems a shout and see where he stands
http://www.reapsystems.co.uk/
He is although quite heavely involved with Thundersky Li-ions but hes well respected with his views etc on li-ion cells
Hes a member on here as well but hasnt posted todate.
I'd love to be able to try a big set in my Blingo but just cant justify that sort of money currently

Hi Ian,
I've been reading with interest your post and had a look at your website.
As an interested buyer of an EV I am a little bit confused by now, which Li-Ion battery is best on the market. Everyone says they have the best! The same as when you buy any other goods...The good thing is though that LifeBatt is giving out a 3 year warranty. That makes it possible to make a better cost/mile calculation.
I run a website (forum) for eco-friendly cars includig EV's. If you like you can mention your new venture there as well. In any case: Good luck with it and I hope to more EV's on the road soon!

Hi ChrisB,
I was thinking more along the lines of a University or other independent non-commercial institution, but looking at REAP's website, they do appear to be very reputable and have considerable lithium battery experience.
Attached below is a Lifebatt Initial Capacity Test, one of a series being conducted at Sandia National Labs Power Sources Development Dept. New Mexico.
Sandia's full report will be available on line at their website on a month or two, when cycle testing is complete.
Cheers,
Ian

Hi stefan72,
Yes, we are unique in the market, no one else offers anything like our garuntee. 3years or 1,500 cycles, whichever the sooner. We are able to do this because we supply not only the cells, but a complete battery pack with BMS and charger. Our chargers, depending on packs size are 1C, i.e. one hour chargers. If there is sufficent input current, our 'Speedy' chargers can charger a pack from flat to full in 20 mins (3C) without damage or loss of cycle life.
Sorry, starting to sound like a salesman. I'm just excited about our product and can't help going on about it.
I checked out your forum, you have some good ideas, I hope this goes well you and I have bookmarked it.
Many thanks,
Ian

Dennis actually started his whole investigation from memory at Southampton Uni I think then he turned it into a bussiness from what he gained from uni.
So with your BMS, does it cover the cells from abuse then i.e over discharge voltage and current ? and in what form does it do this if it does.

NO, they are nothing to do with LiFeBATT !!!!!
This appears to be an importer of Chinese LiFePO4 cells.
My own experience of CHinese LiFePO4 batteries has been very expensive and disappointing. I have over £3,000 worth sitting under my work brench that were either DOA, or failed within a few weeks of testing. Only one out of the 8 packs, from four different vendors, has lasted long enough to make it into one of my ebikes. I have never been able to succesfully claim on the delivery insurance, because the exporter 'forgot' to pay the premium, or get my money back.
This was part of my market research, from June to Sept 07, before I became involved in LiFeBATT.
