Have you heard of Mezzo Soprano? They mod the AK100 and 120 similar to the RWAK w/WM8741 DAC but they still can be used without an amp because they have software volume control = Very slick!

 

I am sure they could also replace your battery...;)

So, the battery, unfortunately is wrapped in a lot of tape and paper? The power cables that connects to the unit goes to a small circuit board which is attached to the wrapping around the battery. So, I think I'm going to avoid trying to do it myself. It could get ugly and there's really no marking on the battery wrapping to give me a clue what brand or type it is.

 

Since I'm going to send it in to RWA for a battery replacement most likely now, I figured I may as well just have them mod it. I was wondering whether to get the S mod which disables the stand-a-lone use and makes it a DAC with a line out along with an upgraded chip or just get the standard mod which gives a more useful output impedance but gives the option of a stand-a-lone.

The battery is easy to remove. You just peel it out, pop the connection clip, then remove a couple of screw to extract the metal shield plate. Once I got that far, though, I realized just how tiny the components are on the circuit board. (You don't get a good sense of that looking at the photos online.) To give you an idea, the smallest tip I have for my soldering iron is 0.79 millimeters, and that's bigger than the size of the surface mount pads on the board. So I decided not to attempt to mod it myself, at least not yet. I've done lots of soldering over the years, but never on parts this small.

 

I suggest not DIYing the mod unless: a) you have a soldering iron with a really, really small tip; b) you have a magnifier/microscope that will allow you to see the components clearly (you may have a hard time soldering this board with the naked eye); and c) you are highly experienced at precision soldering. This is definitely not a beginner soldering project.

^ I agree with all of that. After opening, I realized the same thing.

Guys

 

What is the name of cable to connect the AK100 into ifi DSD and Chord Hugo or any Portable amp?

Use a cheapo ($20) Fiio interconnect unless you want to pay more for an expensive one ;-) I've used one with both my amps (JDS C5 & Fiio E12 DIY)) & AK100 for almost a year now & it's fine.

So, after opening up my battery ak100 and checking the battery. It turns out that the two bare wires that connect the battery to the board through the connector were lose. Since they are bare, I think that might have been what was causing them to drain even when the ak100 was off.

 

I was able to put them back in tightly and now the battery lasts just fine. So, all is good after all regarding my battery. That being said, if I do get the mod by either Phantom or RWA, I will have them replace the batter, because, why not?
