The low-battery indicator can be switched between alkaline or lithium-polymer threshold, so you can use either chemistry without leaving unnecessary capacity in the battery (patent pending). Battery estimates below. Now, the Riggy-Micro series of preamps (RM333) will get considerably longer battery life, as it does not have the headphone, meter, or AGC Disable circuitry (and, it will be smaller and lighter). The Riggy-Assist is designed to be used with cameras which do not have manual control, meters, or headphones. The preamp adds AGC Disable, meters, and headphones that are missing in the camera. If your camera already has those features, then check out the Riggy-Micro line of preamps. The Riggy-Assist can also be used as a XLR front end to digital audio recorders. Here are some of the many companion devices used with the Riggy-Micro.
