RE-Building A123 Packs

[JThiessen]

I got the pack put back together again (I'll call this one - Humpty). I used braided copper desoldering wire to join the packs together again - worked pretty slick (I read about doing this on a thread here somewhere).
Balance charged it, and its sitting at 3.30 and 3.31V.

So all in all, the first one was a success so far.

I also have to thank those that recommended the Hakko Soldering iron to me in another thread. I never would have accomplished it without a good iron.

I pulled one more pack apart last night and found it to be the same end of the pack that was bad. But these cells wont take a charge. They run up to about .13V, the charger gives the low voltage error, and I end up restarting at zero. Attempted several times..guess I'll stop by the LHS and pick up a few cells (they have them for 19 each - not a good price, but.....convenient).

I too bought A123 packs from hopmeup (2x 9.9v 2300mAh) and so far 3 of the cells have died, I have not checked the dates on the cells but will do later. Where is the best place to buy loose cells that havn't been sitting for two years?

Cheers
