BT3.0 Connectors

The BT3.0 connectors are a 3PIN terminal, two metal pins with a diameter of 1.3mm are used for battery discharge, and two metal pins with a diameter of 1.3mm and a metal pin with a diameter of 1.0mm are combined into a 3PIN connector as a balanced charger for battery charging. The BT3.0 connectors have polarity marks on their welding cup but don't support reverse connections.
