Is the BT-LH80W a battery eater? at DVinfo.net

I notice the BT-LH80W's power consumption is 1.5A. ...and other monitors like Nebtek and Marshall are only consuming 800mA or .8A ...that's almost fifty percent lower than the panny!

Can I really get twice the run time using a different monitor such as the Nebtek versus the BT-LH80W?

What's your real world experience using the BT-LH80W off batteries? I plan on using an anton bauer power tap to 4pin xlr to the BT-LH80W if it matters... (I'm hoping I don't need an arsenal just for one monitor.)

Thanks,
Lonnie

The Panasonic can run directly with an Anton Bauer Battery without the power tap cable you described and when I use mine I get plenty of time using a Hytron 50. The other day I got about 8 hours using a Hytron 140 without a change. If you want to run it with the same battery as your camera then you might find the run time with your camera is dramatically shortened. If you are using a large camera they usually draw about 25 to 30 Watts. The monitor might be drawing 18 to 20 Watts so the total could be 43 to 50 Watts giving you a runtime of the two operating together of about 60% compared to the camera alone.Also the stronger the draw the shorter the battery can sustain it. Anton Bauer has some runtime charts on there website if you want exact numbers for your model battery.
