Greg: I would be interersted in knowing the type of battery your friend was using. I think if you look closer at the Anton/Bauer product line, you will find a battery that matches your runtime requirements and your budget. Don’t overlook the value of a 3 year warranty. I can’t think of many other products in the video industry with a 3 year warranty. Remember to look at the wattage load you trying to power. Include your camera/deck and lighting load to select the proper battery. If you need assistance, I am willing to help.
