Alessandro Gaffuri Posted September 21, 2012 Report Share Posted September 21, 2012 I use 8 batteries duracell 24500 mAh now, to power the recorder but charge is very very small, at most with PH48V for the mic. Can you suggest me a good solution? Li.ion battery? Thank you very much. All the best! Quote Link to comment Share on other sites More sharing options...
Mike Matthews Posted September 21, 2012 Report Share Posted September 21, 2012 I use an NP-1 with a BDS to power everything in my bag including the DR-680 and it lasts all day powering the mixer, the recorder, a couple of Lectros and one mic. Since the specs of the DR-680 say not to exceed 14 (I think) volts, I put in a variable output voltage regulator so it gets a constant 12 volts. I know some people say they feed the DR-680 directly from the NP-1, (which can put out 16.8 volts) but I didn't feel comfortable exceeding the specs. It cost me about $30 for a variable output voltage regulator, a radio shack box and the switchcraft connectors. If you are interested in going this route, let me know and I'll send you some pictures and a link to where I bought the variable output voltage regulator. This solution has worked great for me.

Max Hirtenstein Posted September 21, 2012 Report Share Posted September 21, 2012 get a hawk-woods DVSQN4s. it outputs 12v so it won't fry the Tascam. I power a DR-680 and SD302 with 2 NP-F970 batteries and get over 20 hours runtime. Quote Link to comment Share on other sites More sharing options...
efksound Posted September 21, 2012 Report Share Posted September 21, 2012 I have 2 of these ones, quite good for the price and they last around 6-8hrs on the DR680 depending on use and number of ph48 mics.The bad part is the very slow charger, takes around 8 hrs to charge the battery (empty to full) http://www.dealextre...-129717?item=32 Quote Link to comment Share on other sites More sharing options...
Alessandro Gaffuri Posted September 22, 2012 Author Report Share Posted September 22, 2012 Thank you for suggestion. I'm going to see these possibilities. Quote Link to comment Share on other sites More sharing options...
pampasound Posted September 23, 2012 Report Share Posted September 23, 2012 I power a 302 and dr680 with np-1 from B4B and so far no need of power converter. I run for about 8-10 hours before I change battery. I paid $115 for each battery and about $200 for the charger....very good price when comparing to IDX...

sergiofucchi Posted September 24, 2012 Report Share Posted September 24, 2012 I use Tracer battery Li-pol battey packs. They are very small: 10A - 12V. It fit well in my Petrol bag. Quote Link to comment Share on other sites More sharing options...
Alessandro Gaffuri Posted September 24, 2012 Author Report Share Posted September 24, 2012 Where you bought Tracer batteries Sergio? B4B & HW are very good products, but I'm located in italy and I'n not found a good dealer. Thank you efk, your suggestion is very cheap (and the best at the moment).

Erick Posted September 28, 2012 Report Share Posted September 28, 2012 I guess the problem is the charge of the batteries, I've used the tascam 680 (not mine) with 1 mkh416 shotgun and 3 lavs for 4 hours without problems, using 2700 mA batteries and a charger maha mh-c801d Saludos!

Plunkett Sound Posted December 5, 2012 Report Share Posted December 5, 2012 I am looking to power my Tascam DR-680 with NP1 batteries and am considering buying the Hawkwoods NPR-FR2 adapter. http://www.hawkwoods.com/products/details/details.php?code=npr-fr2&mainMenuItemToSlide=5&asi=np-70&asi2=mr4 It is designed to be used with the Fostex FR-2 but it looks like it should work with the Tascam DR-680. I have just contacted Tascam and Hawkwoods about it and I'm waiting for a response. I was wondering if anyone had used this adapter or knew anything about it.

I was wondering if anyone had used this adapter or knew anything about it. that looks very similar to my np1 shoe for the Dr-680. When you speak to hawkwoods make sure they know it's for a dr-680, as the connection is center positive on the recorder rather than negative. Just needs opposite wiring which they do at no extra cost. Other than that works like a charm. I get about 6-8 hours runtime from a hawkwoods np35, or around 20 hours from a np70.

sergiofucchi Posted December 5, 2012 Report Share Posted December 5, 2012 Another alternative is to use the Powerex batteries, 2700 mAh, and quick charger of eight batteries. Sergio. Quote Link to comment Share on other sites More sharing options...
daniel Posted December 7, 2012 Report Share Posted December 7, 2012 Annoyingly the (my) dr-680 still needs internal batteries (aa) even when powering externally (unless i'm missing a way to work round this). dan. Quote Link to comment Share on other sites More sharing options...
sergiofucchi Posted December 7, 2012 Report Share Posted December 7, 2012 Powerex batteries are 1.2V 2700 mAh size AA. However, it is very strange, because my DR-680 without internal batteries, works with an external battery connected to the connector of external power supply. Sergio.

daniel Posted December 7, 2012 Report Share Posted December 7, 2012 Thanks Sergio. Intriguingly it would seem to have something to do with the regulated (12 volt) connector supplied by kortwich as the recorder will power up from the mains adapter without aa batteries (as you would expect). I guess i need to contact kortwich (hat) about this. dan. Quote Link to comment Share on other sites More sharing options...

daniel Posted December 7, 2012 Report Share Posted December 7, 2012 Thanks Mark. So Mark you use a regulated HW Np1 shoe and Sergio you use a (native) 12v Deben battery. I have Np1s batteries and 2 shoes, 1 of which i put a male/female Dtap connector so i could use the regulated (12v) Dtap connector from Kortwich (which they said would work) and look where it's got me :-) Dan.

daniel Posted December 7, 2012 Report Share Posted December 7, 2012 And to be fair to Allessandro (who's thread i've started to hijack) - What battery? Without having used 1 myself, but based upon spec, price and Sergio's experience I would go for the DEBEN option (if i didn't already own NP1s). I still maintain that the male/female Dtap connectors (PCX3) make a cheap (without switches) distribution system if you need 1 :-) dan. ps a few more tests on my Kortwich regulated power cable and i have some more incongruous results to report: If I power up the recorder with both internal and external batteries present and then remove 1 of the internal batteries the recorder remains powered (i've not tried this while recording). Whats even more strange about this is when the internal batteries died on a previous occasion the recorder powered down (during a take - ouch) despite external power being present - my mileage is certainly varying(?)

Hi Mark I just looked again at your post. So did you send your adapter shoe back to Hawkwoods to be rewired? Also, the Fostex FR-2 and the Tascam DR-680 are both centre positive, so surely that wouldn't be an issue. Quote Link to comment Share on other sites More sharing options...

Also, the Fostex FR-2 and the Tascam DR-680 are both centre positive, so surely that wouldn't be an issue. I bought it directly from hawkwoods, wired as such. Checking the model number it's the the NPA-90 shoe not the dedicated FR2 model. Quote Link to comment Share on other sites More sharing options...
sergiofucchi Posted December 10, 2012 Report Share Posted December 10, 2012 In any case, you could solve the problem by leaving within eight alkaline batteries, which, however, will never be used except, perhaps, only at power up. Quote Link to comment Share on other sites More sharing options...
the quieter you become Posted April 2, 2014 Report Share Posted April 2, 2014 Here: http://www.deben.com In the site You can buy on-line, as I do. So with tracer batt. you plug the tascam just with a cable included, correct Sergio? Quote Link to comment Share on other sites More sharing options...
IronFilm Posted July 24, 2018 Report Share Posted July 24, 2018 Sold my spare Tascam DR680 mk1 to a friend, and now trying to help him out with a spare battery as the Feelworld FW4600BP I could easily source years ago for myself has become rather rare/expensive! So to update this thread for 2018, I believe this is the answer: Get a USB 5V to 5.5 x 2.1mm 12V converter cable:https://www.aliexpress.com/item/USB-DC-5V-to-DC-12V-Step-Up-Cable-Module-USB-Power-Boost-Line-Step-Up/32820458733.html Then all you need next is a super cheap USB powerbank:https://www.aliexpress.com/item/2018-hot-sale-Ultrathin-12000-mAh-Portable-USB-Battery-Charger-Power-Bank-For-Iphone-Smart-Cell/32858041818.html The Feelworld battery I used before (which would kinda almost sort of last me a whole day, thus I had two external batteries back then which was always plenty for even the longest day) was 4600mAh but rated for 12V. This USB powerbank is claimed to be 12000mAh however for only 5V, thus I guess this powerbank would only last a little while longer than Feelworld battery I used to use (or maybe even about the same length, once you subtract out the effeciency losses from converting 5V up to 12V). Am I correct in my assessments here, or have I made a fatal flaw? Or any other better or more affordable suggestions I should consider instead?

I'm looking for an A/C *and* battery solution for my newly-acquired DR680. Did you ever get that converter cable to see if it actually works? Sounds too good to be true -- if that works then any standard 5V USB wall adapter (with 2A output) and decent battery would work?! I'm not an electrician and this regulated/unregulated conversation/testing is a bit more than I care to deal with -- although I understand that having reliable voltage is important.
