Topic: V-3 Remote Power 2013

[Fluffyhead4V]

Got a photo of that dual feed cable?? Would love to check it out now that I have a V3 to power up as well. I have a Tekkeon 3300 that I've used for other devices without issue - but recent threads have made me wary.

Thanks

dunno if this has bearing but the Tenergy LI-Ion 18650 battery got some bad reviews....the battery linked IS NOT Li-Ion

So what other good v3 powering solutions exist that are reasonably priced?

The 9.6v nimh batteries always seemed like a good solution:

If people are comfortable with a little hacking and don't mind not having a battery strength meter:

Get a cheap Sony NP-F960 style battery charger (these are the batteries used by the Sound Devices 7xx recorders) like this one:

http://www.amazon.com/eForCity-BATTERY-CHARGER-Compatible-NP-F970/dp/B0041PMDOQ/ref=pd_cp_p_2

The top "tray" of the charger slides out (I think these were designed so the charger portion could remain the same and a variety of sleds could be made to slide into the charger portion, allowing a wider variety of batteries to be accommodated).



Hack into that top tray and add a cable with the switchcraft locking connector needed by the V3.  I found this pretty easy, as the tray on the charger I got had a back plate held on with tiny screws.  Get a jeweler's phillips head, pop off the back, and the only thing in there is a couple wires between the battery side connectors and the connection plate to the charger portion (all the charging electronics are in the charger portion). Easy enough to just solder in a wire for your switchcraft connector for the V3.

Then you can use this as a battery sled that accepts NP-F960 and NP-F970 batteries.  The knockoff versions can be had pretty cheap.  I had gotten some from ebay for like $25 each that worked great.  One of these batteries should power the V3 for 7-8 hours.

I'd get a different charger than the hacked one to actually charge the batteries though.

That looks brilliant.  Does the battery stay in the sled, or could it slide out easily?

The battery clicks firmly into place, so it doesn't slide out.

I should also add that the V3 can be set up for 6v operation or 12v operation.  These batteries are 7.2v.  No problem at all with operating the V3 at 7.2v, but the low battery indicator will not work properly.  You don't want to over-discharge li-ion batteries, so if you run the V3 at the 6v option and the low battery light comes on with these 7.2v nominal li-ion batteries, it is pretty much time to stop recording.

Hey Chris

All three replacements failed. One last Summer and the last two a few weeks ago. I am warning people here not to rely on them. 6 for 6 failure rate was as bad as it can get.

I can echo this as 100% true...  I'm on my third Tekkeon battery, 18 months in (with moderate use, two or three shows a month) and it's totally unreliable.  Died at a show last night, got home, plugged it into the charger, it showed 80% of the battery and charged in 25 minutes to "full" power.  These are garbage for what you pay.  These batteries should cost $30, not $160.  I need to use this thing tomorrow, and I'm taking an A/C adaptor with me and a power strip.  Something that I shouldn't ever have to do after paying that much for a battery.   

Needless to say, I'm looking for new options for powering my V2 (6v).  This feels like a dumb question, but how do I get a cable from: http://www.amazon.com/Lenmar-DVDU923-Universal-Battery-Portable/dp/B0011MZORU to plug into the V2?  The power connector on the V2 is a little weird...  Who makes those around here?   What kind of run-time do people get on those?  When people said 'dual cable,' is that because they are running two batteries?  Is that required, or more for the purpose of swapping? 

Thanks!

I bought two of these and I would not recommend buying them. They are only 2700mah, and only power my V3 for 2-3 hours at most.

Thanks!  I tracked down a 20000 mah battery on ebay that had selectable voltage down to 9v.  It seems those are getting harder to find, or my search skills are worsening.  Once I get it, I'll try to run it down a few times to see what kind of run times I'm getting.

That was my impression from doing the math on the spec.   Thanks for the confirmation.

It's sad that portable dvd players are an outdated concept and we can no longer find and benefit from the batteries that powered them.  I miss the rb-270, though I still have two of them in good condition.  They seem to last for years.  I thought I was paying a lot when I snagged one at best buy way back in 2007 or so.

I know a lot of folks have used nimh rc packs.  Those are still inexpensive, and powerful.  Anyone still running them?

[jdmatt68]

no issues using the naztech at 9v with a 6v V3?

[drchen]

I would not recommending running a 6V V3 with a 9V batt. 
7.2V batt is OK.

[tgakidis]

I ran my v3 for years with 9v DVD batteries until I picked up a tekkeon.

i've run my v3 off a 9v lithium for years
