it is in user manual section but 3 parts are to big can not upload...

I like this Batterie 6800mA it will run for approx 15 hours and its so cheap & light and a newer ones (3800 mA @ 12V) have 5V USB too

Three things on these batteries. 1 -no meters.  2-power switch cab easily be turned off.  3- a friend and I are going back and forth about noise from the battery.  it's low and is down in a mic self noise range, but it is there.  Compared to the 9V dvd batteries which do not have the noise.   and I'll post the link later got take off right now.

Yes they are black stinky and made of plastic
1 Why Meters, Tascam sucks 350mA : 6800 = 19 hrs (I never tape that long)
2. The newer ones have bigger Switch with resistance
3. Noise what Noise. I have 5 dead silent. The only noise I hear is from the refrigerator

Switch is still a potnetial probelm.  I put some guards next to mine in order to preven accidentailly have it turned off in a gear bag.

Now I see what is the trouble the 12 Volts alone dont have this issue? Check cranking up silence with different Batts

Made some tests with el chaepo chineese firecracker (Lipo) 12V & 12/ 5V batt, if you switch on all Phantom 1/2 3/4 5/6 one of noisesources is gone... Some of the noise is from the Tascam herself :-( bitch!

I have one of these cheapo "tri-voltage" batteries, but have been reluctant to take it out yet.
I does have long run-time but I haven't tested the noise yet.
Are they lithium ion or lithium polymer?
I just got into rc cars and the big boys all use lipo batteries (with the added fun of torching, fireworks, smoke, explosion)
Are lipo's appropriate for runnin audio gear?

I use Wally-World, LiIon's and NiMh AA's, and have thought about trying LiPo. Do they have (need) voltage regulation?
I built a 12v pack out of NiMh AA's to run my DR-680. (2 sets of 8 AA's parallel)
I need schooling on which flavors of batteries need voltage regulation and why.

Sanyo Eneeloop are cool long lasting capacity  85% over a year. Leave them always  inside as backup, or for short recordings.
Very low inner impendance much better then NMHY
