Camera Battery Runtime Calculator
How long will a V-mount or NP-F battery power your rig? Watt-hours ÷ camera draw → runtime, plus how many batteries a shoot day needs.
A 98 Wh V-mount running a 28 W rig lasts about 3 hours of real use — not the 3.5 the label math suggests, because cells age, cold sets in, and cameras shut down before true zero (the 0.85 derate here). Add up the whole rig, not just the camera: a 5-inch monitor adds 10–12 W, a wireless transmitter 6–8 W, a focus motor spikes more. The 98 Wh figure matters for flying: lithium batteries over 100 Wh need airline approval, which is why production batteries cluster just under it.
