Thanks fossyant! I googled the name and immediately a few options came up, this being the first:

It looks like it gives the correct 2S2P settup so that's great.
I'm going to choose some 18650s later and a seperare charger. I noticed that the highest capacity (~3400) 18650s on Torchy's ebay are unprotected. I'm hesitant to get those as I can see myself over-discharging them, I might look around for some protected 3,000mAh+ cells or get some slightly lower protected ones since I'm only driving one T6. I can keep the stock charger to reset the protected cells should I ever trip them.
EDIT: I've just spotted the lack of stock on the first two Google links so I'll have to do some further searching, I know what I'm looking for now though so that's good.
Thanks for the suggestion fossyant, but two of those are a bit steep for the money and time for wiring them. I've found the case for sale on an American site here:

The option to add to cart is greyed out for me, possibly because they don't post to the UK, possibly because they're out of stock. I'm going to get an American friend to see if they have the option to order, and IF they're willing to, buy and post to me. If anyone else is interested I would be happy to add to the order and divvy the postage cost, a bit like what fossyant did.
But don't get your hopes up, there are a lot of ifs. Alternatively, we may be able to do another 'bulk' order from China?
how has everyone found the solar storm x3? or are there better out there for the money? I'm starting my commutes next week so want to sort before the clock change.
cheers, Kev
