Wouldn’t it be great if your goggles could show you that your LiPo is running low and that it’s time to land? No problem!

In the Power & Battery tab, you can even set at which voltage you want to be warned. If the Minimum Cell Voltage is dropped, your OSD will warn you with the message: “LAND NOW!”. Dropping below the warning value only triggers “LOW BATTERY”.

Depending on how you fly and which batteries you use, you should adjust these values to your needs. For example, Li-Ion packs are not really empty at 3.5 V per cell. A constant warning in your goggles would be annoying if you still have 15 minutes of flight time.

To make sure the flight controller measures voltage and current correctly, the Scale and Offset values must match the values specified by the manufacturer. Selecting the flash target usually sets these values correctly, but it’s still a good idea to double-check the documentation for your FC and ESC to make sure the numbers are right.

The rule applies again: it’s better to check everything while you’re at the PC than to get frustrated in the field because the FC is reading 3 volts on a fully charged battery.
