Never mind, I looked at my pics from when I opened the Fiio E17 and see that the battery is soldered to the motherboard of the amp.

It was easy to replace, de-soldered the old one and soldered the new one in. I get over 12 hours with this battery, also you can use it to replace the one in the E7 but I wouldn't try to solder it to the board because there's almost no room. I just soldered the wires to the wires of the old battery.
