# Main Battery Placement

{% hint style="warning" %}
Always fly with a fully charged battery **(at least 95%)**.

## Placing the Main Battery

The DeltaQuad Evo has a battery bay (blue), a payload bay (green), and an avionics bay (red).

The main battery needs to be placed on the tray in the battery bay which is located at the front of the fuselage.&#x20;

The tray has the same form and shape as the underside of the battery.&#x20;

The battery must be placed in such a way that it fits on the tray.

The thicker power cables must exit the bottom of the battery and lead over the top of the battery toward the XT90 socket of the DeltaQuad Evo.

{% hint style="info" %}
The battery tray will move forward or backward to correct for the center of gravity depending on which payload is installed.&#x20;
{% endhint %}

{% hint style="warning" %}
Always make sure that **no battery cable** is located between the battery and the back wall of the battery bay.
