# SL8/Astro Battery Connectors

**We recommend all Astro pilots routinely check the aircraft and SL8 battery connectors for signs of damage, debris, or excessive wear.**

## Inspect Connectors 

* Inspect the battery connectors on Astro for melted plastic and / or solder at the base of the power pins. **Do not fly Astro if a connector is damaged** and contact Freefly Support for further guidance . Note some wear and marking is normal on Astro side connectors  
* Inspect all SL8 battery connectors for melted plastic, debris, or dirt. **Do not fly any SL8 battery if the connector is damaged** and contact Freefly Support for further guidance. 
* Debris and dirt can be gently removed with compressed air from the SL8 connector
* Astro aircraft side connectors can be cleaned with compressesd air or with a toothbrush and 99% Isoproply Alcohol 

{% hint style="danger" %}
Never remove debris from the battery with tweezers. If debris cannot be removed from the battery with compressed air, the battery may need to be returned to Freefly or disposed of.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.freeflysystems.com/astro/maintenance/standard-maintenance-procedures/sl8-astro-battery-connectors.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.
