    If you posted the brand of your battery you would likely get an answer from someone who has the same pack.
    I would think it is probably 12g but if you take a sample in to the shop you could compare it to whats on the shelf.

    14 GA Silicone will work fine and be the easiest to solder .... but 12 GA Dean's Wet Noodle would be IMO the best choice.
    I make tap adapters and power harnesses.

    Thanks a lot! I stink at soldering, so I might go with the easiest choice then!
    Anyone now where I can get shrink tubes like the ones original on the battery packs?

    I just left a site that has all the battery pack parts you are looking for. it is www.cheapbatterypacks.com. I left there to come here and ask anyone if they make their own packs? I thought it might be a way to save money and just make my own. but I think they have everything your looking for.

    Make sure you buy wire with a high strand count. They are more flexible, and better suited for RC applications.
    Two Rusty VXLs, M2Ks 18/83 - Tag! You're it!

    Agreed on #14 gauge. Plenty adequate for a NiMH pack.

    Any decent NiMH battery pack can benefit by switching from 14awg to 12awg Wet Noodle. I've done it and have graphs to back me up.

    Great stuff, that W.S. Deans Wet Noodle.

    Edit:
    Hmmm, then again I did end-to-end solder the cells at the same time, so that may have skewed the results.

    I save my 14awg wire for charge adapters anyway.
