Tascam BH-4AA – 4AA Battery Holder for FR-AV4

What is the Tascam BH-4AA?

The Tascam BH-4AA is a spare 4-AA battery holder built for the Tascam FR-AV4 field recorder, giving AV professionals a fast way to swap power in the field without opening the recorder's battery compartment for individual cells. As a dedicated FR-AV4 battery holder, it holds four standard AA batteries in a single removable tray, so a pre-loaded spare can be carried and dropped in during a shoot, live event, or multi-camera production. This makes it a practical accessory for anyone running quick-swap battery power on a Tascam field recorder in run-and-gun or long-session recording environments. It ships as a standalone accessory and does not include batteries.

What does the Tascam BH-4AA do?

The BH-4AA functions as a removable battery tray for the Tascam FR-AV4, the 32-bit float 4-channel field recorder with mixer, timecode generator, and HDMI sync. Rather than replacing AA cells one at a time inside the recorder, the operator pulls the depleted BH-4AA tray and inserts a second, pre-loaded holder, cutting changeover time to seconds. This is the kind of detail that matters on production sets, in broadcast and video production workflows, and on any job where the FR-AV4 needs to stay recording through long takes, interviews, or multi-hour events with minimal downtime. Because it is a dedicated Tascam FR-AV4 accessory, it is built to the exact form factor of that recorder's battery bay, so fit and contact alignment are not a concern the way they can be with generic AA holders. Keeping one or two spare BH-4AA holders pre-loaded is a low-cost way to extend effective runtime on the FR-AV4 without carrying a separate external battery pack or running an AC adapter to a location. This is a straightforward, passive hardware accessory: it holds and delivers battery power to the recorder, with no electronics, firmware, or configuration involved. For integrators and production teams standardizing on the FR-AV4 across multiple units, ordering a few extra BH-4AA holders per recorder is an easy way to build in quick-swap redundancy for field audio capture. It is a small, low-cost line item worth including alongside the recorder itself when outfitting a field kit.
