As David says, the cover for the power pole connector will only stay closed for a few seconds before popping back out.. at first.. mine will stay closed now but I can very clearly see cracks in the plastic that connects the cover to the plug so I don't think it will last too much longer. A 15Ah Bioenno battery fits very well crosswise inside in the middle, without the included hook and loop tape it stays in place without sliding around. With it in the center it has a nice sense of balance when carried. There is also plenty of room for the charger. I don't really like how tight one of the wire links from the volt meter and USB charger is, it can be seen in the photo above.
