HELP with this battery pack.

Feb 13, 2008 3:50am
Any suggestions on what to use to link the - to + for my battery pack. I tried soldering it but the metals wont stick. Is there some kind of clue I can use? What do you suggest O-B-1-Canobi?

Dont know the correct name but I seen one with 2 rows of 3 side by side and one laying horizontal at the bottom (Mini 8.4V). A total of 7 batteries.

use pieces of 16 Ga. wiring. Clean off the ends of the cells. Use finger nail file and file them down a bit. Not some serious filing but more like scuff them up a bit. Use some good electronic solder like 60/40 and Rosin flux. Flux and tin-up the ends of your wires and on the cells too. Then go ahead and solder up the pack. If you need to solder the other cells end to end then I suggest you take it to a RC hobby store and ask them. They will have the proper solder tip to do that.

you can buy copper solder wick at radio shack, thats what I've used for years in RC. it comes in a little reel, it looks like a flat copper braid that has been flattened to a ribbon. Its used to suck up excess solder normally, but makes for great flexible battery bars.
aaaahhhhhhhhhhgh!

Its all good, went to Home Depot last night and bought some BernzOmatic flux electrical solder. Going to try it out in about an hour.

By the way don't forget that Heat is the Killer of all batteries so you have about 1/10 of a second till the solder hardens. Also don't leave the heat on to long on the battery you will runin it. Use a 40w solder Iron with a hammer tip for the best results. If you F- it up I will; be at Pinnacle next sat Building my packs i could fix it.
