⚡ Hollyland Mars 400S (SDI/HDMI) • Power Profile
- Operating Voltage: 6V to 16V DC (DC Barrel Input) / 7.4V Integrated NP-F Plate
- Power Draw — Transmitter (TX): ~11W (<11W official rating)
- Power Draw — Receiver (RX): ~7W (<7W official rating)
- Power Options: Integrated Sony NP-F battery plate (7.4V), DC barrel input via D-Tap cable, or included DC adapter
⏱️ Transmitter (TX) Runtime (~11W Draw @ 85% Efficiency)
- 🔋 1x NP-F 570 (26Wh): ~2.0 hours (2h 01m)
- 🔋 1x NP-F 770 (47Wh): ~3.6 hours (3h 38m)
- 🔋 1x NP-F 980 (74Wh): ~5.7 hours (5h 43m)
- 🔋 V-Mount 98Wh (via D-Tap to DC): ~7.6 hours (7h 34m)
⏱️ Receiver (RX) Runtime (~7W Draw @ 85% Efficiency)
- 🔋 1x NP-F 570 (26Wh): ~3.2 hours (3h 09m)
- 🔋 1x NP-F 770 (47Wh): ~5.7 hours (5h 42m)
- 🔋 1x NP-F 980 (74Wh): ~9.0 hours (8h 59m)
- 🔋 V-Mount 98Wh (via D-Tap to DC): ~11.9 hours (11h 54m)
📊 The 85% Efficiency Standard
- Usable Capacity: Runtimes apply a 0.85 multiplier (Usable Wh = Rated Wh × 0.85) to account for low-voltage RF cutoff protection and DC-DC conversion heat loss.
⚠️ Production Note: Because the TX (~11W) works harder encoding and broadcasting RF than the RX (~7W), always place your higher-capacity battery on the Transmitter unit.
