I have a JVC GY-DV500 camera and I am looking for some additional batteries. We currently have 2 AB TrimPac14s and an AB Dual Charger. I want to upgrade our battery size without breaking the bank. I was wondering if anyone had experience with any of the varizoom batteries. It seems you can get more Wh for the buck with the Varizooms. But I can not find any reviews of them. Thank you for any and all replies. Have a great day.
