My batery box is located in the front grips, and all the other batteries are either to small (9.6 volt minimum) or they are not made for my gun.
What do you mean by too small? 9.6v for a gun like that is more than enough. 8.4 would do the trick as well. Look up cheapbatterypacks.com they have custom made packs for about the same as a brand name new one and they're configured to the way you want them with whatever cells you want.
