9 volt Lithium Ion battery
« on: May 23, 2004, 05:49:22 PM »
$49.97 at most walmarts this thing, IMHO, is pretty sweet!

I'm testing to see how long I get powering the ua-5 and after 7 hours it's still 1/2 full!!  I'll report back with the final time.

Here are some pics of it and the ua-5 as well as some pics with the one of the Hosa converters.

Great find by VA_TAPER!!

I might have a line on a few of these in distressed (read opened) packages)  They would be around $35 shipped, pm me if you would be interested.  

Looks like they are 7.2's not 9v.

Works for UA-5 from what fozzy says tho... Will post update as soon as they arrive...

Do they sell other versions of this battery? Looking for either more voltage or more Ah.

I only ran the test for 8 hours and still showed the battery as 1/2 full.  From this I'm guessing an easy 10+ hours off 1 charge for the ua-5.   Also.....it only took about 5 hours to completely recharge!

A couple questions here.   Is that blue hosa box required to run a UA-5 off this battery?  Instead of a 4 pin connection can I use a RC battery connector?  Also please explain how to reverse the polarity.   I would love to run this with my UA-5 but still a little unclear about how to hook it up.

From the looks of the picture you could just could take an adaptaplug cable and two plugs and hook them up.  To switch ring and tip polarity you just have to rotate the plug 180 deg.

So, BC, the polarity of the battery matches the DC IN on the UA5?  Your photos would seem to indicate that.

Thanks

No the polarity is not matched.....tip and ring have to be swapped.

Like wtreynol said you can easily do this with the adaptaplug.


The Sax??   I'm not familiar with the sax but if it will take 9 volts externally you can always find a way to connect it!!

brian, in those photos, it appears that you're running the ua-5 with no load.  have you run tests powering mics?

They're right next to the portable DVD players.
