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

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

chargin my 7.2ah 12v right now to run some JB3 and UA-5 tests.  I will be testing jb3 w/o internal w/ ua5(home digi mod) into mk012's.  need to upgrade my firmware to set into continuous. i will send results as they come in.  Goal is to have one 7.2 12v run for 10-12 hrs pushing the ua5 and the jb3.  @ $17 thats good for one a day a b-roo

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:
