The M9 Saber Pistol uses a bespoke 7.2V, 2800mAh NiMH rechargable battery pack. This product simply slots in to replace the factory fitted unit.
The MAC11 Micro machine gun also uses the same battery.
The battery is supplied with a molex style connector and high quality 22AWG wire leads. The M9 Saber battery is fitted with a thermal fuse to prevent damage from overheating.
