Here are some more details regarding the PCC modification. My english is far from perfect... But I'll do my best.
Sorry for quality of the pictures made by mobile phone...

Tools (see pics):
1. A soldering iron
2. Mini grinding/drilling machine
3. Drill
4. Tweezers
5. Screw-driver
6. Hot glue pistol (don't know correct name)
7. Half bottle of cognac (optional)

Procedure:
1. Open the case, take out interiors (pic 2).
2. Unsolder a red wire from the pin.
3. Using a soldering iron warm up the pin to melt the glue which is holding it in the body.
4. As soon as glue gets liquid pull out the pin using tweezers from the other end (pic 3).
To adapt contacts of PCC to EVO battery:
5. Grind off mushroom edge on the end of the pin (pic 4, on the shadow on the wall the edge is more visible). Make it parallel but don't shorten the pin and leave it sharp-pointed.
6. Using tweezers or screw-driver pull out a ring plate (pic). You will feel
resistance of a spring soldered to the ring plate. In order the washer has not flown back in the case I used
the battery (pic 5).
7. I have removed a plastic spacer which towers over a surface of the ring plate and prevents contact of a thread part of the battery with plate.
8. To provide isolation of the pin from the plate in the central hole I have covered an external (yellow) part of the pin with hot
glue using a glue pistol. Caution, do not block a free running of an internal and external part of the pin!
After the glue hardens, grind off hillocks, make conical shape on border of a yellow and light part of the pin.
9. Using the drill ream the hole in the body where the pin was fixed (a small blue plastic isolating tube fell out during drilling which
I have thrown away).
10. Gently release the ring plate back in maintaining correct orientation inside.
11. Insert the pin into the hole from the bottom so that it has passed through the hole of the plate.
12. Fit all design back into the PCC case. Insert the Evo Mighty Atom battery and, closing the top cover of PCC adjust
position of the pin in the case, providing good contact. I used an empty battery in order to activate PCC and to see presence
of good contact.
13. Fix the pin using glue pistol, providing its proper orientation.
14. Solder back the red wire.
15. Assemble the PCC and use it.
About two hours and quarter of bottle of cognac I spent for this job.
Hope I've described the job clear enough... Any clarifying questions are welcome...
