DJI TB47 Intelligent Flight Battery for WM610 is a 4500mAh, 22.2V LiPo 6S battery, supporting up to 18 minutes of flight time. The battery also has built-in sensors and bright LEDs that let you know the status and remaining power. It contains automatic discharge feature to avoid swelling (fully charged LiPo cells release hydrogen). Permanent Failure feature is also there, but disabled.
The battery management system chip is queried for data by a small micro-controller (TI MSP430) through a Smart Battery System protocol. That micro-controller sends updates to the FC in regard to current battery status.
The SBS protocol defines battery-related commands to be transferred over SMBus, which in turn is deviced from I2C.
There are multiple versions of the board.
