Hi Folks, I see a recurring question here on the opening of the module. In short, it isn't hard. You basically have to pry it apart along the seam. Some will use a guitar pick, but I happened to have a 1" square of metal (you might have it too... it came with a magnetic phone mount, the metal that sticks to the phone) that was thin and able to get in there to pry and pop it open. I see some people have asked about a larger capacity battery, and while that is certainly possible, I wasn't able to find one. I just replaced it with another 800mah 14500 3.7v battery I found at the local electronics store. MAKE SURE IT HAS SOLDERABLE ENDS ON IT!! Once you pop the top, you've got to pull the circuit board out and disconnect the two connectors. The battery is held in place with some double sided tape on the underside that you can't see, but you'll need a small screwdriver or something to pry it out. Next step is to take the plastic wrapper off to expose the connections. (see my first picture) Then on the top side of the battery, peel the black cover back (it's under the little circuit board) to expose the top battery connector. Cut that silver strip. (see picture 3) You do the same thing on the bottom of the battery. Basically at this point you've got to pay attention to how long the solderable lead is that is on your replacement battery. Mine was about an inch long, so I didn't end up cutting the connector at the very bottom. You can see how I trimmed it in picture 5. Once those two connectors are cut, you move the unit you just cut off onto your new battery. In picture 6 I've soldered that connector that goes down the side of the battery. Do the same thing on the top. Once you've soldered it up, wrap the battery back up with some electrical tape and you're good to go!
