I think you just need to commit to the bit. Granted, it would be madness to go the hack on the frame, but what's stopping you dremelling the guts out the battery? I bet you could make it your bitch then. Bit of hot glue and/or heatshrink, sorted. Bonus, you could probably replace the silly magnetic switch with something more definite, and attach it in the cable guide location.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
Tips:
Create headers by underlining text with ==== or ----
To *italicise* text put one asterisk each side of the word
To **bold** text put two asterisks each side of the word
Embed images by entering:  That's the hard one: exclamation, square brackets and then the URL to the image in brackets.
* Create lists by starting lines with asterisks
1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:
```
Your code goes here
```
Just like Github, a blank line must precede a code block.
If you upload more than 5 files we will display all attachments as thumbnails.
