It is so easy to Ctrl-C and Ctrl-V $6000 worth of LiPo and stuff it into a bike
Yeah, there are pros and cons to having a pack that consists of smaller sub-packs. Pulling it apart to swap out dud cells would be a lot easier with smaller sub-units, but at the same time, that is a lot of connectors and tabs/pins to contend with. It also makes waterproofing a bit harder to maintain too.
I haven't drawn the acetal box for the cells yet, but I'd be getting ahead of myself if I did since I don't really know how much room I will have. An L shape is ideal because it makes use of all of the tank space and still allows a fair bit of weight to slide down into the bike, keeping the CoG a bit lower too. I can make a 120 cell A123 pack in the same manner and it would still fit, but not quite so easily as the LiPos.
Of course a pack of this size is going to weigh 65-75 kg, so you would need a winch to hoist it out of the bike. If I used A123s, I'd virtually never need to do that
But if it was Hobbyking LiPo, then yeah, I'll probably be lumping it out quite a lot of the time. Even if the one-third of the pack was separate, it's still a 40-50 kg mass to haul out.
Gotta hand it to Google - they really made a sweet program with Sketch-up. TurboCAD is bloody clunky and counter-intuitive in comparison.
