Thanks for the info so far, but what I'm trying to figure out is if a non-nunchuck nicad or nimh battery can fit into that handguard.

A traditional 8.4 V mini battery is 6 "vertical" cells (2 columns of 3 cells) and 1 "horizontal". I've never seen a 9.6 V mini of 8 vertical cells (2 columns of of 4, just like a standard large 9.6 V configuration).

Has anybody heard of a mini built in that configuration and has anybody ever seen it fit into an M4 handguard (with perhaps some modification)?

Just looking at it, it seems like it would fit, but I don't want to custom order a battery and have something screw up.

Thanks,
Alex
