I was looking to pick up another Ibera triangle frame bag and I saw they are on sale for the lowest price I've ever seen them, $11.99 right now. They usually retail for at least $20 and the best I've ever been able to snag them for has been $15-$17.
A lot of people really like these bags as an economical way to carry in the front triangle a good amount of lithium, especially lipo bricks. Even some larger batteries fit nicely in these bags, including the notoriously large Ping packs. I shot this clip a year or two ago showing a 48V 10AH ping in the bag.

These Ibera bags aren't as big as the EM3EV bags and they aren't as bulletproof either, but for someone looking for a more affordable way to get your battery into the front triangle, these are a great way to go.
Here are a couple threads with some reviews, plus a photo illustrating the max of 8 6spacks that cal3thousand was able to stuff in one, though he says the zipper gets a little hard to close with that many packs, and 7 packs seems to be a better fit.
