FAQ
Q: Why is this battery pack so wide?
A: Because it houses 3 parallel 32700 cells side by side. The 99mm width flat design is perfect for square boxes or control cabinets. Please double-check the internal width of your battery box before purchasing.
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 (-).
