FAQ
Q: Why doesn't the battery come with a connector?
A: For maximum DIY freedom. Connectors (such as SM, JST, DC barrels) vary significantly by device. By providing bare wires, you can match the exact connector needed for your specific project, avoiding mismatched terminals.
Q: What happens if I connect the red and black wires reversed?
A: The BMS has reverse-polarity protection, but forcing a connection with reversed wires may still damage the board. Please strictly follow: Red wire to the device's positive (+), Black wire to the device's negative (-).
