You can safely set 800 mAh for the larger battery. The profiling process will calculate the actual capacity regardless of the value you enter there.</p> <p>The profiling process for batteries larger than 800 mAh will take longer and the &quot;time remaining&quot; estimate is likely to be off. This is due to the current sinking capabilities on the nPM1300-EK FG board not being designed for large batteries, but it does not affect the quality of the resulting battery model.</p> <p>Best regards,</p> <p>Audun</p><div style="clear:both;"></div>
