HEy all i have a ca m15a4 that has been upgraded to 400 fps with a pdi 170 and other parts. I recently bought a 9.6v 2700 mah nimh battery. It works fine in my un-upgraded 33e, but when i use it in my m15 it pulls the spring back almost all the way then jams. It is not the gun because the 9.6volt 1700 mah nicad battery can still turn the spring easy. So my question is should the nimh battery work on my m15 or do the nimhs not put out enough power to be used in upgraded guns?
I ask this because someone was selling an m249 or m60 that had a pdi 170 in it and they were giving a 8.4 volt 3000 mah battery with it. So i am confused. Any ideas?
