For custom LiFePO4 battery packs, the BMS is the control center. It monitors voltage, current, temperature, state of charge, protection events, and communication with the host device. When OEM buyers ignore communication protocol requirements early, integration delays often appear after mechanical samples are already finished.
Common communication requirements
Many industrial packs require CAN, RS485, UART, Bluetooth, or dry-contact signals. The right choice depends on the charger, vehicle controller, display, cloud platform, and diagnostic tool. Buyers should define message frames, baud rate, alarm codes, SOC logic, and charger handshake requirements before mass production.
Documents to request
Ask for BMS specification, communication protocol table, wiring diagram, connector pinout, protection thresholds, and test report. Related guide: https://www.zjfx-tech.com/post/bms-design-for-custom-lifepo4-battery-packs-buyer-guide
