Best way to get CALB CAxxFI's in the UK ?

I'm looking at getting a dozen CA40fi or CA60fi cells.

Does anyone know a better/cheaper way than from the well known depot in Holland ?

Anyone interested in a group buy and spreading the costs ?

Re: UK EVSE Trade Association disapprove DIY Charging Statio

I do hope you ignore them Kevin.

They are a mere trade organisation, self formed and self governing. They will end up tripping over their own shoe laces over this if left to fester :)

Re: Another EV bike :)

I decided to take a chance with the welder and just get a replacement torch. Unfortunately it isn't completely compatible and connecting the gas line up would be a big faf, so I decided to try going gasless. Newer welding wires with flux cores are getting a good name. After a bit of setting up of th...

Re: Another EV bike :)

A couple of people asked me, via a Youtube video response, for details of the cell discharger. I've decided to post the details int he Cell Monitor group I started a few years ago, and which I'll be working on a bit more in order to apply the cell monitor design to the electric motorcycle project Th...

Re: Another EV bike :)

A quick video of the discharger working is here http://youtu.be/7H0Axly5x-w All layers of the packs are fully charged now. Bringing them up from 4.1V to 4.2V added about 10Ah at low current for nealry 20 hours. Whether that 10Ah of capacity is useful or not I don't know, it might only translate to 2...

Re: Another EV bike :)

it certainly is taking shape now. Great work. Thanks, I've got the packs on a 'topping up' charge, where I'm bringing each 'layer' of 84 cells up from 4.1V to 4.2V. It's not a fast process but I'm being gentle with these cells to start off with because they haven't done any real work for a while. O...

This forum isn't allowing me to post any more photo... Oops, yes. Sorry Chris. That wasn't just you, it was everyone. I have upped the disk quota for photos from 70Mb to 700Mb. That should keep us going for a while. Thanks Tim. I always try to resize my pictures down to a few hundred kb's so hopefu...

Re: Another EV bike :)

I will try and take some shots of the Valence battery pack. The valence packs are made into 12v analogue casings with part of an onboard BMS (It needs other parts) its made up of over 90 separate cells like yours, in four layers. But thats more self evident if I take some photsos. I opened up anoth...
