Tamiya connector polarity

[desmobob]

As I anticipate building the Tamiya Hornet Evo kit I have en route, I was digging through my old RC stuff and found two 7.2V 6-cell stick packs. The plugs are wired in different polarities.

Which is correct for the Tamiya car... red/positive to the half-round side of the plug, or black/negative to the half-round side?

It will become obvious when I get a look at the model's supplied ESC and I'll probably convert to Deans, but I'm curious.

Thank you, gentlemen.

Just as a heads up, I believe Tamiya mini molex are backwards to 6 cell.

Help,
I've attached a photo of two batteries. The small battery came with my Redcat Ridgerunner with the
As you can see from the photo the I have it plugged into a multi cord adapter to charge but the red and black are switched around. So to charge this battery do I need to switch the wires on the battery or the cord adapter. And if I do then it would be wrong for when it's plugged into the car. And if it needs switched those it need switched on the 3S battery? I'm so confused, don't want to burn up $40 batteries.. Would like to run the 3S battery in my Ridgerunner, is there a better way...

Always double check the plug on the vehicle, you never know when someone is in a hurry and assembling some backwards.
