@teastain2 as you can see from the pic I posted "normal" version has black wire (-?) on the left and red wire (+?) on the right. The "F" version of the connector has polarity reversed.

@teastain2

so the right version is the normal one or the F version of the connector?

Hi everyone, I just ordered a T Deck. I want to make it portable using an internal battery, what are the specs of the connector of the battery?
I think it uses a JST connector but which one? there are a few measures (1.5 2.0 2.54mm) and kinds according to aliexpress sellers.

Which one is the right one? Especially positive is the red or the black wire?

Thank you for your help
