solderless power tubes for a123 batteries

[suicideneil]

Given some of the 'videos' Ive seen on the 'certain websites' (before I stopped watching in horror/disgust), I doubt I could poop them very far, but anyway...

I dunno, it just seems a rather strange solution to assembling packs, when everyother piece of advice or common knowledge points to a solid solder joint as the best way. Since these solder tubes do hold the cells securely though (assuming they are assembled with care and attention), I guess the paste could pass the current between cells okay- I wouldnt mind knowing more about the upper limits of what is do-able before losses resulting in excess heat became a factor- hot gooey liquid might tend to trickle where its not wanted and result in a possible short or loss of connection... (that didnt sound at all rude in my mind).
