Just received a pair of Lipo 7.2 volt batteries (RB-Sta-07). The batteries have a balance charge connector (which works), a small 2 pin PCB connector (which is showing the correct voltage) and a 2.1mm barrel connector which is not showing any voltage on either of the batteries. Anyone have the same issue with this product?
Hi,
how are you measuring the voltage on the barrel connector?
It is possible that the pin of your multimeter is not touching the inside of the barrel.

Hi, I have done an analysis and it looks like the ground going to the barrel plug is not connected (on both batteries). I am getting a good voltage on the small connector. No voltage between ground on the barrel and positive on the small connector but good voltage (8+) between ground on the small connector and positive on the barrel. I need the barrel connector and don’t want to have to do a splice on a new battery.
I have made a test with the battery and end up with the same result as you.
I believe that there is a circuit inside the battery and the barrel connector is to charge the battery only.
Let me know if you try it in application.
