I'm still using an ancient one that used to house the SLA battery from my old 'Smart' lights. The DX battery is rattling round inside and the bag itself is falling apart.

What are other people using?

The most popular suggestion used to be the LumiCycle Elite battery bag, but these aren't available anymore, and I don't know what size are of the other bags they still sell:

Personnaly I just use the bag it was originally supplied in, with a piece of velco wrapped round for extra security.

i'm using my topeak alien multi tool pouch as its the perfect size with a bit of extra waterproofing to the battery. Only handy if you've got a multi tool bag but thats what i'm using.

Yep, mine's reasonably waterproof but seeing that thread prompted me to ask about how to attach it to my bike.
