# Charging and storing the battery

## Charging the battery

{% embed url="<https://drive.google.com/file/d/1_CTvWV9KBL_xmFeO6WBqGdlTBX2yzMfJ/view?usp=sharing>" %}

{% hint style="info" %}
The DeltaQuad Evo Li-ion battery is capable of charging within 1 hour at 20 Amperes. Charging at this rate will limit the durability of the battery. It is recommended to charge the battery at no more than 15 Amperes for a maximum lifetime.
{% endhint %}

* Power on the DeltaQuad Dual Charger.
* Plug the yellow XT90 connector from the power cables of the battery into the charger.<br>

* Take the balance lead which is the smaller group of cables with the white connector and plug it into the respective balance port of the charger.&#x20;

* With the DeltaQuad dual charger, you can charge two batteries simultaneously. Therefore make sure to connect the cables of one battery to the same channel.

* Per channel, you have two buttons. One for the current and one for the mode.

* Set the mode to "Charge" by pressing the mode button.

* We recommend charging the DeltaQuad Evo batteries at 15 amperes. You can cycle through the available values by pressing the current button.

* Press start.&#x20;

* Your DeltaQuad Evo battery is now charging.

## Storage charge the battery

{% hint style="info" %}
When not using the battery for a longer period of time it is recommended to storage charge the battery with the provided DeltaQuad Dual Battery Charger. By doing so the battery will be either charged or discharged to 3.7V per cell which equals 50% battery capacity.
{% endhint %}

* Plug in the power and balance cable of the battery to one of the channels of the charger.
* Set the mode to "Storage" by using the mode button.

<figure><img src="/files/3b79zQMbd4XpZKzjCZse" alt="" width="386"><figcaption></figcaption></figure>

* Press "Start".
* 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 the storage mode, the battery will be charged to 50% capacity at the set current value.

## Storing the battery

The battery should be stored in a safe and dark location between 5 and 30 degrees Celsius. If the battery has been fully discharged, putting at least some charge (+- 50%) before long-term storage is recommended. This can be done by using the storage mode of the dual charger.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.deltaquad.com/evo/setup/deltaquad-evo-battery/charging-and-storing-the-battery.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
