I made trouties DIY 1800 lumen lights last year, and made a home made battery pack of 3 x 3 18650 batteries.
These used to fit nicely in to a battery case I had that fitted on the top tube. However my new bike will not take the pack on the top tube. So I need a:
Battery Pouch approx 90 x 62 x 40 cm that will fit to a 90mm oversized stem.
Any ideas?

Bump!
You may be easier putting them in a bottle and sticking that in a bottle cage.
I am slightly confused by your measurements! how are the batteries arranged? I am also presuming the battery measurement are in mm rather than cm as it would be huge otherwise.
if they are in rows of 3 do the 9 batteries not make a square end?
i have seen packs of 4 cell packs mounted to a stem but not more that that.
With the bottle idea you simply rip the drinking nozzle bit out and feed the connector through then re-pack the nozzle with blu-tack or silicone sealant depending on how permanent you want it.
I use this one with my Lumen Liberator. Fit perfectly on the stem.

dunk I have an old Lib bag you can have its a bit muddy bit will fit your batteries
or a new bag like the lumi one. got a box full of those but dont think your battery will fit them
I've converted one of [url= http://www.ribblecycles.co.uk/sp/road-track-bike/Pro-Storage-Bottle/PROATOOL250 ]These[/url] With a cable grommet and a short intermediate cable in the lid to accept a 4x 18650 (Bastid) pack which is pretty loose in there (normally packed out with spares/socks). it might be able to take your 2x3 cell configuration, worth checking the bottle dimensions.
Thanks for the offer Chris, but I think I'm going to try the bottle approach. The one that cookeaa uses looks ideal! I think 3 x 2 on my stem would be a bit heavy and bulky.
The bottle says it fits 74mm bottle cages, I assume thats standard?
