Generic Chinese Bluetooth BMS communication protocol

This is the command sequence sent by the JBDTools software to obtain the battery information. It is a binary string which in HEX format is. I have added the EOLs for clarity.
DD A5 03 00 FF FD 77
DD A5 04 00 FF FC 77
DD A5 05 00 FF FB 77

First two bytes are the header, bytes 3 and 4 are the command, bytes 5 and 6 are the checksum, the last byte is the EOR.

The battery current along with other information that I haven't decoded is returned by the BMS board by the first command. The second command returns the individual cell voltages and the third returns the BMS name in ASCII format and maybe other information.

The reply packet is a binary string in HEX format is. I have added the EOLs for clarity
DD A5 00 1B 13 78 00 00 00 00 03 E8 00 00 22 C7 00 00 00 00 00 00 19 00 03 0C 02 0B 64 0B 5F FC 83 77
DD A5 00 18 10 39 10 3A 10 38 10 3A 10 3C 10 39 10 37 10 39 10 3B 10 3F 10 36 10 3A FC 74 77
DD A5 00 14 4C 48 2D 53 50 31 35 53 30 30 31 2D 50 31 33 53 2D 33 30 41 FB 39 77

The first two bytes are the header, bytes 3 and 4 are the length of the reply data in bytes, the data follows followed by the checksum, and finally the EOR.

The battery current is in bytes 7 and 8 of the first line

The second line are the individual cell voltages. Each voltage is a 16 bit number so 0x1039 gives a voltage of 4153mV
10 39 10 3A 10 38 10 3A 10 3C 10 39 10 37 10 39 10 3B 10 3F 10 36 10 3A
These converted to decimal in mV are 4153 4155 4152 4155 4157 4153 4151 4153 4156 4159 4150 4155

Third line is the BMS name.
