I hope I wasn't one of those who got you mixxed up over whats wrong with the batt's,I thought I sent pretty good instructions.

Anyways Linc, don't worry about the Thunder Power packs. You can toss em' or use if you want.
Hopefully you can make it through the A123's and Zippy's with throwing anything through the window.

Take it easy and good luck!

yeah your a123 cells are pissing me off. I have broken a hammer now, and my bench vice, when I get pissed it is not nice for anything I can get my hands on. You a123 cells are in a pile, I may finish them, or I may not. To be honest they are crap, and I would not contemplate using something this shitty in any of my rc vehicles. I have no idea how well the soldering will hold, but my worst soldering is 80 times better than the crap resistance welds they had stock.

Thanks for the kind words ML. Some sort of horse tranquilizer would be necessary to calm me down right now... I bet I am steaming from the ears...

To everyone else that has lipos here, the a/c in my work room is out, and I do not feel like trying to fix lipos while sweating. It is 110 in the room, and I have no desire to do anything in there.

I have a feeling it is time to take a break from rc. If something pisses me off this much it is not close to being enjoyable and I should stop.

Sorry for gettin you into this man.
If you don't want to finish them I'll understand. Just ship em' back I'll figure something out.

yeah, it does look easy, I wonder what type of flux and solder he is using...

I have made dozens of nimh packs, and am not new to the process by any means. I guess I will give it another try, but plan to have some a/c running by then. 110 degrees and my concentration do not go well together.

Apparently the cells ends have a coating on them that allows regular 60/40 to stick so you just want to scuff them with the Scotchbrit pads and not hit them with a dremel like you might with Ni-xx cells.
On a quick search I found this for flux.

if you want to order some up just bill me for it and your welcome to whatever is left.

I've used regular 60/40 Rosin Core Solder on all kinds of cylindrical cells.

I use the Rosin Core .032 diameter that Radio Shack sells.

A good scuffing really helps things hold and the solder flow. It does take a really hot soldering iron though. A small iron won't work.

Just an update Linc.

I appreciate your advice. I received the Zinc Core Solder and flux, and successfully built 2 - 4S Flightpower 3700mah 25C Packs from the one huge 8S pack.

Just ran them in the Revo yesterday and am very happy. Got a great deal that time.

I also saw that zinc core and amber zinc flux at
