Can anyone help me.
I have converted my old 12 volt 3A power base to a system that is 24 volts using NP-1 Batteries. I am looking to buy dependable NP-1's that have good watt hours. I bought several Switronix Pro-X NP-L60 Lithium Camera Batteries rated at 14.8v 60Wh. I have not been happy with the performance of the batteries. Some of the batteries have not held their charge or from a full charge have rapidly depleted. I am sick of them and intend to call the manufacturer. I have talked to several sound mixers who have recommended IDX NPL7's. Can anyone verify their dependability or offer any suggestions.
