Default Soldering packs......

I'm not a newbie, and i've built quite a few packs, but i have a problem with them staying together for the long run.........I've had a couple break in the past, and I just got 2 new packs that I can't get the solder to stick to at all! Its driving me nuts.....I even tried lightly sanding the ends of the battery to get a better connection.....is there one particular type of solder that works better than others? Elighten me please! Thanks for the help...

ho many watts is your soldering iron and what type of solder do you use, i use 60/40 rosin core solder and it keeps my packs together very well

I use 60w iron and deans silver solder.

I used rosin core solder but it doesn't transfer the heat well enough causing all the mess.

Dens solder is working really well for me.
Fast heat transfer, it melts well and I get a cleaner result.

just to point out here, soldering the cells together just puts an electical contact between them... it wasn't meant to withstand the forces pulling the cells apart (like when you crash, or even mishandling the cells physically). you'd need to physically secure the cells together, like gluing the cells, strapping/securing them tightly...

i guess the point here is that don't overdo the solder... the less solder between the bar and the cell the better... better contact is made by holding the bar against the cell, and applying the solder around the bar/cell contact point.

there was someone here on a prior discussion who is a 'certified solderer' of the navy, excuse the term, it escapes me now... got great tips on soldering... hope he'd join this thread to comment again... i think his handle was buda or something like that...
