This NiMH airsoft battery pack is in a nun-chuck configuration--4 cells end to end on each side--which can also be used in some crane stocks. The important thing to notice about this battery pack is that the main wires and battery connection wires exit on the same side. This is what is required for the crane stock side of things, however, this configuration also works well for the standard nun-chuck packs.

This pack has 2 sections, or nodes, to it.  The dimensions for each node are given below. Please double check the measurements of the battery bay in your gun to assure that the pack will fit.
