BQ41Z90: max battery capacity

Part Number: BQ41Z90
Other Parts Discussed in Thread: BQ34Z100

Tool/software:

What is the max battery capacity (for fuel cauge)?

  • 65 Ah in device comparison table, 32 Ah in user manual. Which one is true and is there a workaround for >32Ah battery?

  • Hi Esko,

    In the current FW the max value enterable value for design capacity is 32ah. The RTM version of the FW will include a current scale factor that will function similar to the scaling on BQ34z100. This feature will allow for higher capacity cell support.

    Regards,

    Diego
