Great looking backpack but not sure if I would ride through Times Square wearing something like that loaded with Lipo packs and wiring? I'm nervous just using two bags hanging over the top bar with wires running out. if someone official ever peeked inside and saw the Lipo bricks with balance plugs in this day and age it would create a great deal of suspicion?
Anyway, I dig your idea but just wanted to point out a couple things I've "noticed" running around metro areas with this stuff.
Here's some photos of my battery carrying setup:

These weatherproof bags slip on/off easily and can hold 20Ah Lipo. Total 12qty 5S Lipo bricks when fully loaded. My normal commute only requires 5-6Ah so, in order to save weight I generally run around with only 6qty 5S bricks. In this configuration I use old Lipo boxes to fill the unused space.

It might seem to interfere with pedaling but it's really not that wide and I never have any pedaling issues.
Peeking inside it would probably seem a little suspicious:

Here's 15s2p 10Ah pack(s) so you can see the series connectors and idea of size - my hands are large but you can get an idea of scale.
You're gonna have a good time, enjoy!
