Battery Assembly Take 2

After 3 hours of soldering, I'm about 70% done with one of the two packs. 2 of the first 3 hours were exploratory until I decided on what specific wiring I was going to use. I decided on 4 strands of solid 18 gauge wire. This will allow for ~24 amps rerouting regardless of the number of failed batteries. This means up to 8 out of 12 equipotential cells can fail before we'll exceed this specification.
FYI: Thicker wire (one strand) is too hard to work with and doesn't solder well. Thinner wire (more strands) has the potential to have stray strands, which could short the cells out if they stray into different potentials.
