Hi Django
I've sent a couple of emails to Mr Ching recently at
ezeebikes@gmail.com requesting replacement Li-ion battery prices for my 2 year old Cadence but have had no reply. Same question to Cyclepoint brought a quick answer but at a huge price - £350. I'm thinking of making do for now taking a charger to work until I hear about the longevity of the new batteries. BTW, has anyone got an empty battery case for sale which I can fill with NimH cells?

Very surprised you didn't get a reply, and it sounds like his spam filter has been hyperactive again, I've known this happen before.
The new battery is made by Sanyo and contains 10 of their cells. Seven of these same cells are in the Panasonic battery that comes with the Kalkhoff, Gazelle and BikeTech bikes and that carries a two year guarantee.
That doesn't absolutely guarantee the new eZee battery life will be exactly the same of course, but it does give more confidence. It also explains the price, since the 24 volt battery for the Kalkhoff is £305, so pro-rata that makes £350 for 36 volts quite low.
Unfortunately all these much improved new generation batteries are coming in more expensive. Wisper are heavily subsidising theirs at present, but it's still ended up dearer than previously. However, the actual cost over time will be lower since they will last very much longer than the earlier rather short lived ones.

cost in China of the new eZee battery is £40 higher than the old one, so with very small manufacturer and retailer margins, export duties and VAT added to that £40, it's not surprising that it's £70 dearer at £350, though it does make the eyes water. It helps to reflect that the similar BionX battery is £450, easing the pain somewhat.
P.S. I have an NiMh battery complete that's only a year old but has done very few miles, just discharged and charged regularly on a charger to keep it healthy. I'll PM you, but you are welcome to it, no charge. The Li-ion charger is no good for it though, you'll need an NiMh charger.
