I'm using a NP-F970 Battery for the Tascam Dr 680, Works great I can get 15 -18 hours out of it, but the battery won't start under its own power. I have to put 8 AA in the rig with external battery plugged in then it automatically kicks in as it was powered by ac. If I leave the AA batteries in for the whole recording ( chance something may power down and I can have time t swap out to another NP-F970 Battery ) they are dead within hours. If I get it where my external batt is recognized and pull out one battery I take the chance of loosing power and ultimately the whole recording.
My question is there a way to power this rig under it's own power using the NP-F970 Battery and when using this battery, I would like it not to also use the AA
Thanks
