Topic: JB3 external power

[John R]

the fuse is in the cig adapter plug.  so i'll be adding one down the line for an xlr end, and keeping it in the adapter for direct 12v times.

sorry, it's a 250v 1.6a

6hrs again for the JB3 and UA5.  just started UA5 tests only w/ the jb3 on ac power and the ua5 on the 7.2 SLA.  

i'll keep ya'll posted.  

tin foil to protect the fuse seems to be working, lol.

the flashlight and lantern come in handy.  thought about running the emergency flashers in a few crowded venues.  powers the jb3 and UA-5 with the help of a power inverter...even jumped the band's bus for the trip home.  gotta love a power supply that multi-tasks...

If you want REALLY long run times and don't mind the weight


12v 18ah for $30 (14lbs)

http://www.batterymart.com/battery.mv?p=SLA-12V18


or if you have a new friend that really wants to help you tape, get this one

12v 35ah for $42 (29 lbs and has its own handle)
http://www.batterymart.com/battery.mv?p=SLA-12V35




The one thing that will make a big difference on run time is the charger.  You have to get a good charger to get good results.  Look for Xantrix or Batteryminder.  (or any pulse type charger)

Just so ya'll know.  I did a test with my jb3, ua-5, and svu-2 on (2) 3000mha rc batts.  Headphones cranked on the svu-2, and ua-5 at almost clip.  I pulled the batts out of the JB3, and used a hacked walmart multi 12v adaptor set at 4.5v.  I got 2 full rounds of 3hr waves on continuous.  Is it supposed to save the last partial wav? Or are we just measuring in 3hr chunks.  If I left the jb3 bats in, would that continue without a source and then i could listen to see where the music stopped for the full time that the batts worked?  One last somewhat unrelated question for all you jb3 gurus:  When I listen to a large wav and try to fast forward to a particular spot, it freezes and goes back to the begining.  The only way I can get it to work is to hit the ff button then quickly hit pause, play, pause, play, pause... then it works.  Is this normal?

Bean, whats up man. Here are your pics. I think Im really gonna love having a digital cam!!!!!

First I hacked the cig lighter part off:


Then, I soldered a 4pin in its place (I also cut off some cable to make it shorter):


This is the final product:


Looks pretty good! If you want any more pics, let me know!  Pretty easy solution. I didnt do all the adaptaplug stuff like SickRick, but this will work just fine for me. THANLKS to everyone who helped in this thread!!! +T!

That right angle was a lot harder to do than I thought it would be!!!

[F.O.Bean]

hehe, when i did mine about 6 months ago, they took about 2 hrs max, but that was only 2 4pins

[fozzy]

The right angle do suck.  I am re-running my 12v tests and snapped a few more pictures i will post tomorrow.  Also my markertek order showed up today w/ some 4pins and green cables so i have been soldering all night.  

[Sterling]

So you guys are Not going to try to run both the Jb3 adn Ua5 off on ebattery?

I thought this would be a good solution, maybe run one battery a day at roo?  

I could just run the UA5 on RC's and the JB3 on a 12V...hmmmm...what do you guys think?
