I have used this 12V L-ion battery from Ebay to power a Tascam DR-680. Does anyone know if it will be good with the F8? Thanks.
Should be good. Probably regulated 12V. As long as you don't feed it higher than 17V all should be fine. And depending on how many mah your bat goes, it'll power F8 for a long time!
I did a test just running internal batts. I was able to record 2 channels for 6 hours before it cut out. And when it cut out it closed the file so there was no data loss.
Cool.. Out of curiosity what AA's were you using in the F8 and were you running headphones/phantom?
Either Powerex 2700 NiMHs or eneloop pro NiMHs.
One channel was phantom, powering a shotgun mic, other was not phantom.
Yes, I had headphones connected and amp turned half up.
I was surprised at how long it went! My Nomad goes 20 minutes on internal batts.
