I'm not sure how I'll be assembling them, because I don't know how to solder to aluminum. If that is too hard, I will just configure the packs without soldering, like this:


I'm not sure how the bus bars will hold up, but I think they will be ok. I think for the 2s packs, I'll just bend the batteries over so that they are end-to-end. I'm not sure what I'll do with the 3s packs, as my rusty's chassis can't fit 3 in a row, or 2 side-by-side. I'll think of something:027:.

BTW, the pack is somewhere in MD right now :D

If you get the FLM Rusty chassis, you can fit 3s flatpack with ease.

Yeah, I thought about an FLM chassis, but I would rather spend the $60 on better electronics. I have yet to get a Mamba 5700, so that's another $180 down the hole, plus the $100 or so for the charger. I'll just do some custom cutting on the chassis to make the packs fit. I'm sure I'll think of some way to do it.

Now that I think about it, I think making the packs SxS would be better to fit in my boat. What I may do to my Rustler is dremel down the little lip by the battery tray so that it is flush with the chassis and I can put the A123's in there SxS.

Well, the battery just came in a couple hours ago. I have already dismantled it to just the cells. I measured the whole pack and it read about 32.9v-33v. I left my soldering iron down at the lake with my other tools, so I won't be able to put leads on the packs yet. I have taken a few pictures during the process, so I'll post those later. We'll see how it goes from here. The charger and power supply are next on the list.
