just to let you know after 9 months my 37volt phylion ezee liv battery pack has died.it was on its way out after 3 months but i decided to soldier on.ive now got 3 small 7ah sealed lead acid batterys which i will try and adapt.as i cannot justify £250 for a replacement as i recelled my lafree for £100.also ive noticed that 50cycles no longer stock these bikes.as an aside ive placed an order for a subaru elcat electric van.50mph and 40mile range.these were used as post office vans in finland.hopefully it will arrive before the end of july.
ezee liv battery now dead

Hi Subevo, the agents for eZeebike in the UK are now:
Cyclepoint
The Liv is still a current model.
Interesting to hear about your van purchase. I know it's not a bike, but please keep us informed about how you get on with it.

That is the top of the range Sanyo celled battery - although expensive it will last years and years so will pay for itself over time. There is a cheaper Phylion celled battery at around £280 which should do the trick. Experience is proving that these batteries are lasting longer than the awful original 2006/(early)2007 versions, so should be a good buy.
--------------------------------------------------------------------------
i realise its guess work but "years and years".....how many ?...and the £280 one how many ?.....if years and years is say 3 then that could work out a lot cheaper then 2 of the others that have now got a one year warranty...thats if ive read things right...and i never would bet on that..lol
In the end you pay your money and take your choice. The Sanyo cells are very good quality, as recognised by panasonic who offer a 2 year guarantee. How long will they last? I have no idea, it depends on how you use them or if you abuse them. If I was in the market for a battery I would wait for the later ezee battery to come to the market. Then again the Sanyo cells are very light weight so tempting, but at £400? Do the sums, if it last 4 years then it is good value at £100 a year. Choices, choices.
I think that eZee are likely to have the Li-polymer version of the new batteries at least initially, and at 3.3 kilos it's almost as light as the Sanyo. Having had the heavier 4.6 kilo Li-ion manganese serve me so well this year, that's my favourite. The prices for these two could well change, Sanyo as with many Japanese branded products being much more expensive than Chinese ones.

From the description, am I right in thinking the £395 batteries are the new 3.3kg non-phylion lithium polymer ones, the sanyos were Li+, 3.1kg £350?

I believe they are still the Sanyo ones Stuart, since the newer ones that have been on test are only now being chosen for use.
Wai Won has said that the new Phylion ones had only been sent out as warranty replacements, not mentioning any supply of the Li-polymer yet.

Ok, thanks: the apparently changed battery description on Cyclepoint & Wai Won saying
I just realised that the 4.6kg 14Ah Phylion you tested is no heavier than the previous 4.5kg 10Ah Phylion, and is the same LiMn chemistry, so its essentially a substantial 40% increase in capacity for the same weight.
PS I think the Phylion 14Ah would be my preference too, as if you didn't know!

(in the context of the results of the recent battery tests and the 3.3kg li-polymer being the one adopted) made me think the new ones were available now, or maybe I'm just being thrown by the description - I don't recall the sanyo being described as a polymer previously, though that may be true for all I know!

That's what I think Stuart, but I'm open to correction as Cyclepoint may be receiving new supplies now.
As you say, there's been no gain weight for the observed gain in capacity in the Phylion, but remember I haven't measured the capacity.
With these lithium batteries, a failure to deliver current at an adequate rate results in an effective reduction in capacity, and as we all know, the earlier battery did fail to deliver. Therefore it's effective capacity in normal use on my Quando could have been say 7 Ah rather than the nominal 10 Ah.
It follows the the observed range increase indicating a nominal 14 Ah could mean an actual 10 Ah on the later battery. However, that doesn't affect owners who get the proportional increase in range anyway, but it could mean that the two batteries are the same capacity and therefore the same weight, the difference being that the latter one delivers the whole capacity rather than falling short.

Since I've only used the 9Ah Ezee NiMH, that would be my only baseline to gauge from: I always got the impression that the earlier phylions could, at best, slightly outdistance the NiMH, though at worst soon fall rather short of course.
On that basis, it would be interesting to compare the estimated capacity in practice of the new lithium batteries with the older 9Ah rated NiMH, though the results of your tough testing suggest the phylions would normally comfortably outdistance them, whatever capacity they're nominally rated at if they become available.
I expect many ezee riders will be comparing with the earlier ezee lithiums though, as you say, which is probably a more straightforward like-for-like comparison.

You're right Stuart, substantially greater perceived capacity over the NiMh batteries, so a gain in real terms.
Though once again variability intrudes, since the early NiMh batteries were better than later ones, no fault of the manufacturer but just reflecting the greatly reduced availability of NiMh high discharge rate D cells at viable prices.
That's why the last NiMh batteries were 8.5 Ah in lieu of the previous 9 Ah, and with a lower maximum discharge rate.
