Oh OK ... Thanks ... And I didn't know that they are named for dimensions.. Seems obvious now that you say it ktm ... So thanks for the extra info... Also... Thats a good idea with the fabric strip dejay... I can't speak with experience with using epoxy on fabric but the only thing I would think wouldn't work so well is cotton ... I would probabaly try something like nylon ...but that's just a guess
That goes for almost all LiIon batteries. 18350, 14500 (AA), 10440 (AAA), etc. They're basic dimensions of the batteries but it can vary by manufacturer.
