So, I just wanted to let everyone know, with full rig running, I got a little over 45 hours... Not too much different from before! This sucker really does not draw that much...

I'm sorry... I'm too damn lazy to read a 15 pg thread to figure out what I missed!!!  Am I correct in thinking that the concensus is that a 7.2 Ah sla will run a jb3 for 45 hrs by using a hacked car charger?  Will (should) that work with a 9.6 nimh ( time based on amp'g) as well?  And a general question:  how many mAh's in = 1Ah?   Is it 1000 mAh = 1 Ah?  And is full rig running meaning that its the jb3 + x?  Thanks for doing all the work guys, but could someone post a full recap?

Thanks and +T's

I do think taping is the reality of the business..it is also an impetus for artists to create studio CDs that are ART, not just another recording...    Fareed Haque  2-4-2005

I got a little over 45 hours...

180 mA according to the Powersonic graph. Download here:

http://www.power-sonic.com/techman.pdf GRAPH IS ON PAGE 6.

The more the discharge current is, the lower the capacity becomes. This graph shows the discharge time v. current.

Enjoy taping some LONG festivals this summer everyone! Thanks to Alex for running the tests!

So, the JB3 and UA5 (assuming 550 mA for UA5) can be run for about 11 hours with a 7.2 mAh, 16 hours with a 12 mAh.

Will (should) that work with a 9.6 nimh ( time based on amp'g) as well?  

62 hours on a 9.6 by my graphing skills...

And yes, 1 Amp = 1000 mAmp

so who wants to sell me a 12v plus charger, if the jb3 can go THAT long, a 7.2a would be ideal, but id take a 4.2a also

Wow I have a 12V 12amp battery...actually two fo them...is that too much? Man...I'm kinda drunk right now (hee hee)! Hey Bean if you want I'll sell ya one of these big dogs but I just want to see how long this big mother will run for both the UA5 adn the JB3. Are the 12V 7a ALOT less heavy than the 12amp? this is going to be great  :pepper:
