i have some 7.4V li-ions from when i used to have a mytek. they were the ones from (batteryspace?) with the coiled cables for bike lights. i can dig em up if youre interested.

I'd take a gander at them if you can dig them up.

Looking for updates on remote power to power my V3. Have several DVD batteries. Only a handful still get me through a typical show. Once charged if not used, lose power after a day or so of sitting unused. Looking for new options. Is this one still good?  https://www.amazon.com/gp/product/B00ME3ZH7C/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Any sug's/rec's are appreciated.

We have been using these

https://www.amazon.com/TalentCell-Rechargeable-11000mAh-14500mAh-26400mAh/dp/B016BJCRUO?ref_=bl_dp_s_web_8899093011

its about the size of a juice box. We still have the maxoaks but they are pretty heavy / footprint for one off shows. So we went with the above recently and using the 9v to run the 6v V3 and V2s. They run much cooler at 9v
Im sure the talentcell you linked to would be fine but I have only used the one i linked.

ok i beleive its 2 batts and a charger. ill dig em up and load test. they were only used once or twice but are a few years old

ANYONE KNOW THE ESTIMATED RUN TIME ON THE TALENT CELL? V3 AND 680?

THANKS!

I thought this would be a quick calculation, but there were some snags.  A good exercise though!

The V3 manual uses a draw of 0.75 amps in their battery life calculation (assuming A/D is on and phantom is on).
https://www.gracedesign.com/support/manuals/v3_manual_RevE_online.pdf

The DR-680 manual says that phantom draws 3 mA per channel, which is just wrong.  But they give run times for Eneloop NiMH batteries (2 Ah capacity), and from there, we can get to the current draw.  They say 4 hours with 6 phantom channels, which would be 2 Ah / 4 = 0.5 amps.  Without phantom power they say 5.5 hours which would be 0.364 amps.  [So the difference of 0.136 amps across 6 phantom channels would be about 23 mA of extra current per phantom channel.]
https://tascam.com/downloads/products/tascam/dr-680mkii/e_dr-680mk2_om_vb.pdf

Since we’ll be using a TalentCell battery to feed both 9V to the V3 and 12V to the DR-680, the calculations are smoother if we convert the amps to watts:
V3 draws 0.75 amps at 9 volts = 6.75 watts
DR-680 draws 0.5 -or- 0.364 amps at 12 volts = 6 watts -or- 4.36 watts
Combined, the V3 and DR-680 use 12.75 watts -or- 11.11 watts

The smaller TalentCell battery has a 100 Wh capacity.  The manual says that you’ve got 25% left when it goes to one light.  Using that, the run time should be 6.75 -or- 5.88 hours depending on whether you’ve got phantom power turned off or are using it on all 6 channels on the DR-680.  I’m guessing that you could push it another hour or so without a problem.

The larger 132 Wh TalentCell battery will give you about 8.9 -or- 7.8 hours.

I run the larger TalentCell with 2 channels of phantom power on the DR-680 at festivals and in theory I should get 20 hours down to one light.  That sounds about right, since I rarely get to two lights when running all day.

Ladies and Gentleman,

thats doing your homework!! :cheers:

hey thanks, since I know this works I just need a cable for my V3, and Im back taping! >:D

a few years away from the game and with spending so much foolish money on portable power over the years,this is a huge help. I've had the V3 for 2 years and never even powered it.
thanks for your help! :headphones:

The DR-680 manual says that phantom draws 3 mA per channel, which is just wrong. 

how is that "wrong"?

currents vary quite a bit from microphone to microphone. some require up to 10mA, some as little as 1mA

Ahhh - I see your point.  That info on phantom power current draw was in a section with the text below:

Battery operation time (when used continuously)
  NiMH batteries (eneloop)
    About 4 hours (6 channels of phantom power used, 3 mA per channel)
    About 4.5 hours (2 channels of phantom power used, 3 mA per channel)
    About 5.5 hours (phantom power not used)

I presumed they were talking about 3 mA at 12 volts since they were talking about battery power.  But that 3 mA draw spec may refer to 48 V, which makes much more sense.
