Hi Javier
in my v19 bms the settings are
UART - 001 (able to be changed)
UART2-016 (not able to be changed - greyed out)
there is no UART 3
I have CAN protocal set to 004 (Victron CAN bus)
One other thing. If you work with slave batteries, then set the RCV and 100% voltage on the slaves a bit lower then the master.
This way the batteries will better sync to 100%.
Hello Darktooth
You mention: Lower RCV to the recommended voltage for your cell (3.45 as per data sheet)
What datasheet are you referring to?
My batteries are also YiXiang Energy units. I don’t know if I have a JK V19, the model number is JK-PB2A16S20P. I have six of them, and they work perfectly with the following DIP switch settings:
Battery 1 (master): 0000
Battery 2: 1000
Battery 3: 0100
Battery 4: 1100
Battery 5: 0010
Battery 6: 1010
0 is down, 1 is up. So it’s just binary counting, except the least significant bit is on the left instead of the right.
I haven’t messed with a UART setting; I don’t see one in my setup.
CAN Protocol: 004 – Victron_CANbus
I hope this helps to all.
