The SWIT PB-M146S is a pocket-sized V-mount battery engineered for run-and-gun filmmakers and on-set professionals who demand serious power in a carry-anywhere form factor. Delivering 146Wh / 10.1Ah of fly-friendly capacity at a 14.4V nominal voltage, it keeps your camera rolling longer without weighing down your kit.
Built around SWIT’s innovative Wire-Free internal technology — where all cells, D-Tap, USB, and LED indicator components are soldered directly onto the PCB with no internal wiring — the PB-M146S offers reduced internal resistance for a circuit that is stable, safe, and consistently reliable under a 150W / 12A constant high load.
Key features
