This approach results in relatively coarse estimations due to fluctuations in the estimated charge as the measured voltage changes under load.

To configure the basic battery settings for battery 1:

1. Start *QGroundControl* and connect the vehicle.
1. Select the **Gear** icon (Vehicle Setup) in the top toolbar and then **Power** in the sidebar.
1. Select the **Q menu > Vehicle Setup** to open vehicle settings, and then **Power** in the sidebar.

You are presented with the basic settings that characterize the battery.
The sections below explain what values to set for each field.

This opens the *Power Setup* configuration screen

1. Set the values for Battery 1 in the indicated section (the values to enter are discussed in the following sections).
1. If you have a second battery, change the *Source* to "Battery Module" in the Battery 2 section and set the values in the same way as for Battery 1.

:::note
At time of writing *QGroundControl* only allows you to set values for battery 1 in this view.
For vehicles with multiple batteries you'll need to directly [set the parameters](../advanced_config/parameters.md) for battery 2 (`BAT2_*`), as described in the following sections.

This load compensation method estimates the load based on the total thrust that gets commanded to the motors.

:::caution
:::warning
This method is not particularly accurate because there's a delay between thrust command and current, and because the thrust in not linearly proportional to the current.
Use [Current-based Load Compensation](#current_based_load_compensation) instead if your vehicle has a current sensor.
