# Charging the Battery

{% embed url="<https://youtu.be/3ZmXkAarzbs>" %}

{% hint style="info" %}
The DeltaQuad Evo Li-ion battery can be charged within 1 hour at 20 amperes. Charging at this rate may limit the battery’s durability. It is recommended to charge the battery at no more than **15 amperes** to maximize its lifetime.
{% endhint %}

* Power on the DeltaQuad Evo Dual Charger.&#x20;
* Plug the yellow XT90 connector from the battery's power cables into the charger.

* With the DeltaQuad Evo Dual Charger, you can charge two batteries simultaneously. Therefore, make sure to connect the cables of each battery to the appropriate channel.

* Each channel has two buttons: one for **Current** and one for **Mode**.

{% hint style="info" %}
The higher the charging current, the greater the impact on the battery's life expectancy; conversely, the lower the charging current, the longer the battery's life expectancy.
{% endhint %}

## Storage Charge the Battery

{% hint style="info" %}
When not using the battery for an extended period, it is recommended to store it with the provided DeltaQuad Dual Battery Charger. This will ensure the battery is charged or discharged to 3.7V per cell, which equals 50% of its capacity.
{% endhint %}

* Plug the power and balance cables of the battery into one of the channels on the charger.&#x20;
* Set the mode to **Storage** by pressing the **Mode** button.

* Press **Start**.

{% hint style="info" %}
If the battery is fully charged when using the **Storage** mode, the charger will discharge the battery to 50% of its capacity. This process can take longer as the discharge power per channel is only 40W.

If the battery is below 50% capacity when using Storage mode, the charger will bring it up to 50% capacity at the set current value.
