Inside the stock are plastic ribs (and the plastic round spacer in the middle of the stock you see in the above pics, cut these out) down each side that hold the stock battery from rattling around in any TM or Cyma ak with a plastic stock.
If you cut these out you can fit a larger battery in the space on an angle if you sand down or remove the plastic on each side. It takes some work but I have done it to all my TM AK stocks and they fit 9.6v sanyo Nicad 2000 MAH batteries. Yours battery may be slightly bigger but should still fit.
