Hi! I just order a Zaxcom Maxx and I thinking about the battery system for it. I had thought in a Sony NPF battery system and Hawk-Woods adapter. It would be: -Hawk-woods DV-SQN2S (12V) (with the possibility of power too a Lectrosonics receiver) -2x Sony NPF-970 6600mAh 7.2V I have doubts about which could be the duration of each battery (run time) with Maxx? Typical configuration, 1 channel phantom power and 4 channel recording. Sorry by my English! Thanks!!
