I was really hoping to mount them in the triangle, but it seems like i'm running into issues with that. I ordered a triangle bag from Lunacycle, and it came in with some really messed up tolerances. The two sides of the bag are noticeably not the same size. Regardless of the quality of the bag, there is absolutely no way those packs would fit in that bag. I could fit 3 of them, 4 would have fit if the tolerances weren't messed up. Obviously that won't work.
What are the other mounting options you guys have seen / used? Are there any much larger triangle bags you know of?
I'd really prefer to keep the weight centrally mounted if possible rather than having them hanging way off the back.
Temporarily I have them stuck in a backpack... but that's not an ideal location because these things are really heavy. Starts to hurt my shoulders from the weight after ~15 min, which is nothing when you have a pack this size.
You should be realizing by now that you put "The cart before the horse."
For future reference, or for anyone else looking at building a pack, a more sensible approach is;
1)Build/buy the enclosure to fit the donor bike.
2)Mock up perfered "bricks" out of cardboard and trial fit to determine configuration and capacity.
It would seem to me, your only choice is to reduce capacity, as 32 Ah is needlessly large. My pack is 25 Ah(Which couled easily fit in a large frame bag)and that works out to almost 50 miles. I can't remember the last time I even came close to using the full pack, as 50 miles for the routes and speeds I travel, makes for a very long ride.
Having said that, here is how I carry 25 Ah;
I carry 4) 6S/10Ah bricks in the frame bag for 12S/20Ah(12S is a much easier Voltage to work with, BTW). If I mounted my controllers outside the frame bag, I could fit 2 more 6S/10Ah bricks for a 12S/30Ah pack.
In addition, I carry 2 6S/5Ah bricks in a tube on the frt. of the bike's down tube, for an additional 12S/5Ah. That would be a total of 12S/35Ah w/out much difficulty. But, with my current pack size(25Ah), the bike weighs 75 Lb.s and I really wouldn't want it to be much heavier.
How do you charge your pack?
