Sony BP-V47 PMW-EX330 Replacement Battery 14.8V 3200mAh

Sony PMW-EX330 / PMW-F5 Series — 14.8V Li-ion Replacement Battery (BP-V47)

This is a 14.8V, 3200mAh (47.36Wh) lithium-ion battery replacing the Sony BP-V47 and BP-FL75. It fits the PMW-EX330, PMW-F5, PMW-F55, and PMW-400 professional camcorders. These are shoulder-mount broadcast and cinema cameras used in live production, ENG, and narrative work.

• PMW-EX330 / PMW-F5 / PMW-F55 platform fit: These models share the same V-mount battery interface and 14.8V power rail. The BMS handshake protocol is consistent across the series, so one cell services all listed bodies without adapter or modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the PMW-EX330 body. The BMS accepted the cell on first install, voltage draw during 4K recording held stable, and thermal cutoff did not trigger under sustained load.
• First-cycle acceptance on Sony broadcast bodies: On initial install, perform one complete charge cycle using the OEM Sony charger before going to set. Some PMW-series bodies require a full charge cycle to map the new cell's discharge curve and display accurate battery-remaining percentages on the viewfinder readout.

Sony PMW-F5 BMS rejecting a third-party cell on first power-up

The PMW-F5 and F55 run a stricter BMS authentication routine than the EX-series bodies. On first install, the camera checks the cell's voltage signature before allowing draw. If the cell ships at storage voltage (around 11–12V), the body may flag it as unrecognised and refuse to power on. Charge the cell fully in an OEM-compatible Sony charger before inserting it into the camera body. Once the cell reaches 16.8V and is re-inserted, the BMS completes its check and accepts it normally.

Battery percentage jumping erratically on the viewfinder display

This happens when the camera's fuel gauge is still calibrated to the discharge curve of the old, degraded cell. A new cell has a flatter, more stable voltage curve — the camera misreads this as erratic capacity. Run the new cell from 100% down to auto-shutoff in a single session without interrupting the discharge. After one full cycle, the PMW body recalibrates its indicator thresholds and the readout stabilises. If the jumping persists after two cycles, check that the battery contacts on the camera body are clean and making firm contact.
