Making an older LiPo a "balanced" pack
Hi all, going on the theory of there being no such thing as a stupid question.....
Can you add the balancing wires to a LiPo that wasnt made with them?
I have some older LiPos that are getting tired, but still have a bit of life left. I also just got a couple of new ones, as Im getting back into electrics. The new ones all have the balancing wires. I thought if I was very careful with the iron, if it would be appropriate to solder wires onto the battery tabs. I have a battery powered soldering iron that allows me some control over the heat. I could tin up the wires, then hold them on the contacts, apply the iron, and turn it on just until the solder melts. Does that sound like it would work?

I've done that myself with no problem. The method you describe is the one I used as well. As long as you are comfortable with the soldering iron, you should be okay. Just be sure not to short out any of the cells with the iron or wires!

Cool, thanks 
I'll be careful about shorting.... whenever I solder the output leads onto the main plug on one of these batteries, I always do one wire at a time, strip, solder, and heat shrink... before stripping the second wire, so theres no way I can short it with the iron. (or finger, OUCH)
