RAK19016 Efficiency at Different Voltages

Hello,
I was wondering if there is data regarding the RAK19016 efficiency at different input voltages? I’d like potentially use this module in an ultra low power application.

In my case, I’d like to power the board as well as a motor from the same battery (thinking something like 3x 18650’s in series to get in the 10.8v range).

Without a battery connected, the efficiency is defined by the SGM61230 and SGM6036 chips.

We do not have made specific measurements regarding the efficiency.
