Camera Battery Run Time & Power Calculator
Calculate total rig power draw (Watts) and battery endurance in hours and minutes with built-in safety margins.
Input Parameters
Onboard monitor (15W) + Wireless Teradek transmitter (10W) + Wireless focus motors (5W).
Calculation Results
Estimated continuous operating runtime before low-voltage warning.
Total simultaneous power load across all D-Tap / Lemo ports
Camera Power Systems and Battery Safety on Set
Modern digital cinema cameras draw significant current. Adding high-brightness director monitors, wireless video transmitters, and multiple Preston or cforce lens motors can easily push a camera rig's total consumption over 120–150 Watts. Our calculator incorporates an 85% usable battery threshold, which protects against sudden shutdowns when lithium-ion cell voltages drop under load.
Frequently Asked Questions
Q1. What is the IATA battery travel limitation for airline flights?
Lithium-ion batteries under 100Wh can be taken in carry-on luggage without airline quantity limits. Batteries between 100Wh and 160Wh are usually restricted to two spares per passenger with airline approval. Batteries above 160Wh cannot travel on passenger flights.
