But back to the bike :). I'm still waiting on the motor controller; it appears the seller is backordered quite a bit and is waiting on 100 units to come in. 5 days ago he said they'd be here in 7, so I imagine I have 5 days of waiting left ;).
There's definitely stuff I could be doing to ready the bike right now, but I've reached a thinking point on the battery design and don't want to take my bike apart without having a solution for getting it ridable again.
So here's what I have done:

Got my throttle!

Soldered on some bigger 10 gauge cables. Had to go buy a bigger soldering iron; the 15 watt couldn't heat the wire up enough.

Wheel with bigger cables.

Finished wiring up the battery packs. Due to the stiffness of the wire and the size of the finished product, I hate the big connectors and will probably change the configuration. We're developing a new high current product at work and had to custom order a shielded 8 gauge cable. The minimum order was 10000', so needless to say I've been told I can take as much as I need. It's SUPER flexible. So I think what I might do is cut the big hunker blue and gray connectors off and start over, wiring everything with the much smaller 75 Amp Andersons, which I do like. Again, if I had to start over, I'd definitely get the most flexible wire I could find.
With the smaller Andersons I'm considering only wiring two sets of 5 packs together in parallel and then putting each set in series. This would give me an excellent "you're half way out of gas" halfway through my ride; I'd have to switch packs after 50 miles. Not ideal, but I'm still kicking the stump on this thinking point.
I also wired up the parallel connectors: 160 hand solders including 120 inline wire strips... perfect for occupying my hands while I'm on the phone:
All made up:
And plugged in:
That's it for now; work's been keeping me busy and I'm indling until I get the motor controller.
