| Sequential number of the record. If you selected a rate is 1 sec / point, then this is the relative number of seconds
| Time of the clock of the computer that runs the GUI
| Time since the BMS was powered-up or reset.
days:hours:
minutes:seconds
| Current seen by current sensor that is active when the BMS is powered by the Vsource supply input [A]. Positive = discharge
| Current seen by current sensor that is active when the BMS is powered by the Vload supply input [A]. Positive = discharge
| Total pack current [A] Positive = discharge
| Total pack voltage [V]
| State of Charge [%]
| Depth of Discharge [Ah]
| Number of cell boards whose balance load is on
| Cell voltage [V] above which its cell board turns on the balance load.
4.55 V = balancing is off
