My soldering Iron has problems soldering the positive side of these cell's.
I might get some more/aggressive  flux...

You can find holder for you cells and solder them to the charger so you can use all 4 channels.

that strange you have problem with positive as usually it's negative who's harder (thicker so need a big iron).
As positive is a thin part it's probably like you'r thinking, not appropriate flux and not a soldering iron problem)

Try "roughing up" the positive end with a little emery paper or similar, has worked for me also a bit of a rub with isopropyl alcohol sometimes is enough.
Those 26650s are a good score

Thanks for the input guys!

I have a 300W Chinees Iron that melts through... anything.. But I don't want to overheat the cells.
The A123 26650 cells have a different build, the outside/ big surface is the positive side.So that makes the positive harder to solder.

26650 cell holders arrived to extent my chargers Smile.
I made an adapters to fit 4 cells in a charger for testing and it works fine.

If you search the forum everyone keeps buying these shit tools and refuses to spend $100 to get a proper soldering iron...why? It'll make your life 1000% easier...the right tool for the job makes a massive difference...stop throwing away money of shit tools and get yourself a proper iron, you'll save hours and hours and the headache...

This is an awesome build man and the 26650 is the way of the future. I promise you if you get a good tool, your thank yourself for it!

$18 iron did 1000's of soldiers only thing that failed was the tips (from burning off the old winding wire i was using for fuses)

I use this for years for big solders and now for batteries (did 1000+ cells and a lot of big copper bar/cables connexions), the tip is still in nice condition as I clean it each time from corrosive flux (and I use a lot of really corrosive flux on some works...)

For precision stuff I use this JBC 30w with a 1mm tip (the one provided is 2mm I think), was bought on teh same day years ago and the tip is in perfect condition after hundreds of hours of use.

I bought one of those. I have not tried soldering with it yet.  The reviews I read said it works well.  Most of the reviewers are using it for stained glass or copper gutters.


I am concerned that the tip is too wide for the positive contact on the 18650 cells.  
I will start by practicing on bad cells. I may be able to grind down the tip to make it narrower if it is too wide.

Mine was about 30 dollars off eBay.
