    Before I can determine what's going on in your situation, I need some clarification on what you're using.

    • Are you using TI's EV2300 or 2400 USB interface and the accompanying bqEVSW software?
    • Are you using a TI bq20z45 gas gauge EVM (evaluation module) or your own circuit board?
    • Do you have screenshots of the SBS data registers from the bqEVSW software?
