Is there any way to run the battery profiler at 20 uA for the low discharge current? The minimum in the UI is 100 uA.  
Thank you

Hi,

Regarding the lowest possible discharge current, there is a difference between Otii Arc and Otii Ace.  
Otii Arc has the lower limit of 100uA and Otii Ace has the lower limit of 1uA.  
You can find the specification differences here:

> **[Hardware - Qoitech](https://www.qoitech.com/hardware/)**

> Otii hardware High-level comparison. For details see the product datasheets. Otii Arc Otii Ace MAIN Output voltage 0.5V to 5V 0V to 25V Output power, max continuous 12W 30W Output power, max peak 25W 50W Isolated No +-200V   Sink current Max...

Best regards,
