Hi guys,
When I go to check the voltage on my 6V 2700 mah NiMh battery I get two voltages. When I have the connector's curved part (JR Connector) looking one way I get a low voltage of 6.5V. When I flip the connector around, I get a higher voltage of 7.2V. I also used my Triton Jr. to check the voltage and I'm getting the same thing with two different voltages. Which is the right reading?

Using a standard voltmeter on the battery will give you an un-loaded reading which is usually higher than the 'loaded' or the voltage under load, such as plugged into a receiver that has all the servos attached.
But, as I said, I don't quite understand what you are trying to describe by 'the curved part'. If you can take a picture of it or provide a drawing of some sort to describe what you are talking about, then we may be able to help you out.

I'm sorry about the vague description. The JR lead, which goes into the voltmeter, has a red wire and a black wire.I get one voltage with the red wire looking up (the connector is sideways) and I get another voltage with the black wire looking up. So it's flipped 180 degrees when I get the other voltage.
I just connected the charger and something interesting happened. The charger charged the battery with the red wire looking up and not with the black wire looking up. I now know how the connector should be connected because when I go to charge with the black up, the charger rejects it and does not charge. It shows some kind of weird voltage and quits.
This is now why I like Futaba "J" connectors, but no problem!
Thanks for your help!
