BT3.0 Connectors - 10 Pack
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. When welding wires, make sure to pay attention to the positive and negative directions. The connector's design prevents reverse connections, so do not force it in the opposite direction to avoid short circuit risks.
