I'm sure you will check those links again in a year orso, seems to be the way with some connections. Out of the 3 DALY BMS units I have 1 of the 2 200A always calculates the SOC lower than the other one, even when the charge controller was changed and extended the battery cable by 2.5m. I checked today and the 150A BMS in the shed has CAN/485 connection, the 2x200A BMS at the house do not have that connection available for some reason. When everything is working well there is very little (No Work) for the BMS to do...... when there is plenty of solar and plenty of battery capacity left by the next morning.... I will have to put a JUNCTEK on the shopping list.
