Naztech/SD 788 powering question

[Mic D]

Was wondering what voltage other Naztech PB 1500 users are powering their 788's at. 12v? 16v? Also was wondering what run times they were getting. Picked up a PB 1500 recently w/ custom cable to run with a 788T. Thanks.

i have a 744t i power w pb 15000. 2 track most times /phantom .im guessing i get about 8 hrs.plus i can switch over to the sony battery for probably another 4 after the pb 15000is depleted
im guessing you could get close to that. 4 tracks with phantom. plus that depends on the mics and lights etc.

I also power a SD 744t with a Naztech 15000 and found that I had to set it at 16v to get reliable operation.  Same thing with a SD 302 mixer.
