Mojo only works when the battery is not charging( i.e what the battery power is being consumed)?

The LTC2959 measures voltage (1.8V-60V), does this also apply to Mojo?

When powered via USB does the notecard charge the battery via Mojo?

Hi @Pius4109,

Can you check that you are on the latest firmware for the Notecard, you’ll need to update to ensure all the features of the Mojo are available.

Yes, the Mojo does also measure voltage.

Let me know if these issues persist after updating,

Thanks,  
Alex

I am just asking questions, based on what I have read about Mojo.

The Mojo works in a positive direction (mAh consumed) when draining and a negative direction when charging. You can still charge the battery via USB with the Mojo connected, it simply counts the Coulombs in either direction.
