Strongest Triangle Battery Bag

[stevekeys84]

I looked around to find a post similar to this and couldn't really. I see some suggestions of bags here and there but I am wondering what some of you guys think are the strongest and sturdiest. Here is a link to the size chart for my bike. It is the Large size. I have a big triangle. The bag that came with my batter is already splitting at the seams.

I got 6 or 7 years out of the triangle bag from this guy;

Some of the seams are starting to septerate, but it's still intact. But it's starting to get hard as the AZ weather has dried out the material.
My bike was an XL and the XL bag fit perfectly and I would advise an XL for you even if you have to scrunch-up a corner a bit, you want all the space you can get.
The way to make these last is to not to support the weight from the straps, but to support it from the under-side. I installed the bag, then made two holes in the bottom of the bag (using a soldering iron) matching the water bottle holder bosses, then put a 1 X 3 board in the bag and screwed it in.

There are expensive packs but I found falcon best bang for the buck. My stitching awl from backpacking decades is a pretty easy fix. Luna is the worst with recycled cardboard stiffeners. EM3ev is better but the simplest of improvements don’t seem to happen. Nice straps and wrapped foam insert panels.

I have a Moosetreks Touring bag, which fits the Moonlander perfectly, and is the strongest bag I have ever had.

It has really wide and strong Velcro strips.

I lined the bottom with a pvc strip for additional support
