Before first start-up, make sure the board is configured properly:
The board MUST be configured, connectors and solder jumpers need to be soldered and installed to match your exact battery cell count
Solder your power in and power out connectors or wires on the J4 and J5 footprints
Solder the correct cell terminal connector at the JP1 location. Ensure it is correctly positioned and aligned
Configure the board for your application by soldering the corresponding SJxx connectors
Configure the board with additional and/or optional components as described in Configuring the hardware to fit the application requirements
Once the board is configured properly (see Configuring the hardware for more details about configuration), it is time to connect the board.
To power on the RDDRONE-BMS772 board, *first* connect the battery to the power input connector (J4) and then the cell terminal connector (JP1). This protects the boards form internal damage due to hot plugging.
Similarly, to disconnect the battery from the board, the cell terminal connector (JP1) should be disconnected first. Then the power input (J4) can be disconnected.
