Topic: 7.2v/4500mah NIMH DVD battery cable question....

[F.O.Bean]

OK folks, I bought a 7.2v/4500mah NIMH DVD battery, and all it came w/ was the AC Adapter/wall wart. I stopped at Radio Shack tonight and bought an "M" Adaptaplug, and the appropriate cable for the adaptaplug, so I can solder an RC connector on the other end. I'm just in need of assistance. Do I want the tip to be positive

• or negative[-] And how should I go about building it? Just see if the ac adapter has the tip
• [-], and then do the same to the output cable

I DO have a multi-meter so just let me know what I have to do, so I can start using this battery

Thank you VERY MUCH in advance for any help you can give me

You can use your multimeter to find out if the output tip is +.
Is the MM digital?
If you test the output tip (of the battery) with the red lead of the MM, and the tip is -, then the MM will read -7.2 instead of 7.2
Does that make sense?

Also, you have to know if the gear you're going to power is tip+.  Much gear is, but not all.

I am pretty sure you want positive unless you plan on using a UA5 or r4/r44 w/ the battery pack.

Bean as far as I know onlt edirol products use a negative tip.
