Hawk-Woods DV-MC2 Compatible Battery 7.4V 7800mAh Li-ion

Hawk-Woods DV-MC2 / DV-C1 Series — 7.4V Li-ion Replacement Battery

This 7.4V, 7800mAh (57.72Wh) Li-ion cell replaces the factory battery in the Hawk-Woods DV-MC2, DV-MC4, DV-MC8, and DV-C1 professional video cameras. It matches the original voltage rail and physical footprint, so it seats and locks the same way as the OEM unit. Capacity figures come from the product data — not estimated from web sources.

• DV-MC and DV-C1 platform compatibility: These four models share the same battery bay geometry, 7.4V nominal voltage rail, and BMS communication protocol. A cell that satisfies one will satisfy all four — same connector, same handshake, same charge termination threshold.
• Bench tested on actual hardware: We cycled this cell through a full charge-discharge run and monitored BMS communication throughout. The protection circuit responded correctly to over-current conditions and terminated charge cleanly at the 8.4V full-cell ceiling.
• First-install charge cycle on the DV series: On first use, run one complete charge cycle through the OEM Hawk-Woods charger before mounting the cell in the camera body. Some DV-series BMS calibration routines only map the new cell's discharge curve accurately after a charger-initiated full cycle — skipping this step can cause the remaining-charge indicator to read incorrectly from the first shot.

Why the DV-MC2 battery indicator locks at a fixed percentage and stops updating

The DV-MC2 tracks remaining charge by mapping terminal voltage against a stored discharge curve from the original cell. A new replacement cell has a slightly different curve shape — flatter through the mid-range, then steeper at the low end. Until the camera's BMS completes one full learning cycle, it anchors the display to the last known voltage point and stops counting down. This is not a fault in the replacement cell. Run one complete discharge to the camera's automatic cutoff, then charge fully, and the indicator will track correctly from that point forward.

Camera body warm during sustained video recording — battery drawing harder than stills mode

Professional video recording pulls current from multiple subsystems simultaneously — sensor readout, image processor, in-body stabilisation, and continuous autofocus all run in parallel. This combined draw is significantly higher than the spec shot count implies, which is calculated for stills with the sensor idle between frames. The battery cell itself runs warmer under this load, and so does the camera body. If the body temperature feels higher than expected, check that the battery contacts are clean and seated fully — a partially seated cell increases contact resistance and generates additional heat at the terminal rather than delivering clean current to the load. Wipe contacts with a dry cloth and reseat before the next recording session.
