BMS: JBD UP16S010, UP16S015 Decoding based on firmware versions 10.2.1, 12.1.7, 13.2.4, 13.3.2
Commands can be sent via the RS485-1 port, by the RS232 port, or UART (9600baud, N81). At least with these firmware versions, the Bluetooth/Wifi UART port is the only port on master that forwards all 0x78 and 0x79 commands to the slaves. On other ports, only the pack status is available for slaves.
CRC calculation: crc16 with initial_value=0xffff and polynomial=0xa001, LSB 1st
