JST-Anschlussâ bestätigen Sie die Polarität des Geräts und des Anschlusses vor dem Kauf
In their picture the polarity on the connector is reverse to ours. You will have to switch + and GND of the cable.
Despite their message, I donât see an option to select a different polarity when ordering.
However, I have many batteries that came with wrong polarity. It is quite easy to switch the cables directly on the connector.
(1) Lift up the small plastic nose
(2) pull out the cable with the metallic clip
(3) push it back into the connector on the correct position
