Part Number: BQ27426

The design capacity of BQ27426 is 14000 mAh, but the specification is 8000 mAh. Which one is right?

We use three 18650 batteries in parallel, with a total capacity of 10,000 mAh.

Can BQ27426 support it?

Thank you.

Hi Jerry
Did you try programming in 10000 mAh on the gauge and it didn't change? If it changes, then that means the 8000 mAh isn't the valid max for the device. If it is indeed the max, you can still use the gauge following the app note listed below:
