Hello,

I am not sure about the release note, but there was a tag inside the nPM software that indicated the update and included notes about it. Good to hear that it has reduced the profiling time to a great extent.

Kind regards,
Abhijith

Thanks for the answer and you are right.

After updating the nPM PowerUp to version v2.2.2, it took about 1d15hrs for profiling to pass 3000mAh capacity. I was using v2.2.1.

Then, was the update made to nPM1300 where maximum profiling capacity reduced from 3000mAh to 800mAh an accident? I don't see any release note regarding the change.

The problem is that the current sinking capabilities of the FG Board isn't strong enough to discharge large batteries within the same timeframe as smaller batteries. The process involves discharging the battery using 1/5 C pulses, but the FG board can maximum discharge 600 mA or so. This means that a 5000 mAh battery could take twice as long as normal. However, 5 days does sound a bit excessive. Can you look at the "all events" log file and confirm whether the process is still active? The expected output is idle periods of measurements of ibat=0, followed by active periods where ibat=~0.6. The idle period is typicall 20 minutes, and the active period 10 minutes

Hmm thats sounds about right. I did the profiling with 1800mAh battery and its took two complete days to finish. With 5000mAh battery, 4-5days falls in the range. Not sure though why the profiler takes so long anyways. Could be made faster >>>>>>>>

Hello,

What version of the nPM Power UP software are you currently using? There is a new version available (v2.2.2) that supports up to 3000 mAh. Could you please try it out and let me know how it goes?

Kind regards,
