# 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.
* allows authentication of the battery
* allows diagnostics to verify the safe operation of the battery
* allows CAN, I²C and NFC communication
* implements SWD and JTAG debugging interfaces, works with standard Segger J-Link and other debuggers
* 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/bms3.4-9.1/getting-started-with-the-rddrone-bms772/configuring-the-hardware#power-mosfets-and-heatsinks).
