No picture though to show how big it will actually be.

Mugen makes phone batteries? I thought they just did aftermarket parts for Honda.

I ordered a 3800mAh battery. It came with a custom back cover - all for $11.39, which included shipping from Hong Kong!

It works great. I am a light user - can go two days without a charge easy. Plus, I like the bump out on the back, as it makes it easier to grab the phone from my pocket and bring it out right-ride up, making it easier to locate buttons.

All in all, seems like a great deal.

Here's a couple of quick pics:

I have that one too but I purchased it from a US seller for a couple of bucks more. After a few charge/discharge cycles it was almost 3 days before needing to charge. The down side, it does not fit in my leather or silicone cases and the last lime I looked no one was selling any that would fit, also, no NFC, but no one is using that for much. When I have to go into the city where LTE and WiFi access is the norm, I use that bad boy without the slightest worry, unlike my old inspire that might last 4 hours.
