More show than tell here. I did what I like the most. Got the job done as fast as I can, which we can afford here as it's the prototyping phase.

A wood board to hold everything together, AWG 8 wire (spec'ed for the nominal average current) and the XT-90 connectors to match the batteries.

I assume that you already know what needs to be done. If you don't it's probably not a good idea to be messing with this big LiPos without any protection circuit.

Yes, it's a rig. I'm not proud of it. But it works, it got me 1~2 months ahead with actually testing the thing on the road. Don't worry. We'll get back to it to do the proper design, which is the whole focus of this project.

Basic features will be taken into account in the final design these are :

• Each of the 4 packs could be connected/disconnected/removed individually for balancing/maintenance
• Fits the battery storage bay of the bike. Has anchors so that it can be strapped in place.
• Can be carried by hand - not in the pictures but I have a small rope that works as a handle
• Should be able to slide in and out from a Rail.
