BQ20Z45-R1 max design capacity?

32Ah is the correct number for 20z45 as far as I am aware. If I find out where the 65535 number came from I'll let you know

Thanks for the follow-up, Mike.

The 65535mAhr comes from the datasheet so I'm curious as to whether the part can actually be programmed to have a design capacity up to that value.

Looking forward to your reply.

Best Regards,

Kevin

we have a foil where we talk about the max capacity of the gauges when we discuss fooling the calibration in high capacity packs which confirms the 32Ah figure for 20z45 ( and 16Ah for z90) , see here

but this datasheet 65535 number has been buggiing me also for a while so I'll try and find out what's behind it.

I'll be interested to hear the reasoning behind it as well.  The Design Capacity field allows for 2 bytes which would be 65535, but I'm wondering if there isn't something else that is driving the 32000mAhr limit.

Hi Mike,

Any update on this?

Thanks,

Kevin
