# Board features

The RDDRONE-BMS772 integrates the following functions and features: 

* LiPo Battery from 3s to 6s, with stack voltage ranging from 6V to 26V 
* ambient temperature range from -20°C to 60°C 
* measures battery stack and cell voltages with an accuracy of +/-5mV, battery charge or discharge current up to 200A peak and 90A\* DC with an accuracy of 1% for the complete chain and cell temperature with an accuracy of +/- 2°C (including AFE, PCB and NTC inaccuracies) 
* active cell balancing during charging 
* offers a deep sleep mode (for transportation and storage) with <80μA leakage current, as well as an automatic sleep mode with <200μA current consumption on the battery.&#x20;
* allows authentication of the battery&#x20;
* allows diagnostics to verify the safe operation of the battery&#x20;
* allows CAN, I²C and NFC communication&#x20;
* implements SWD and JTAG debugging interfaces, works with standard Segger J-Link and other debuggers&#x20;
* implements DCD-LZ combined debug and uart console interface for use with PX4 DroneCode and HoverGames platforms

***Note**: The 90A DC maximum current is obtained only when all MOSFETs and heatsinks are mounted. See* [*Power MOSFETs and heatsinks*](https://nxp.gitbook.io/rddrone-bms772/getting-started-with-the-rddrone-bms772/configuring-the-hardware#power-mosfets-and-heatsinks).

# Agent Instructions: 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:

```
GET https://nxp.gitbook.io/rddrone-bms772/board-user-guide/getting-to-know-the-hardware/board-features.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
