After you install the BCB box, adjust the disconnection protection threshold of the end-of-
discharge (EOD) based on backup time to avoid overcurrent disconnection. The default values
are as follows:
1.
If backup time < 1 h, EOD is 1.67 V/cell.
2.
If 1 h ≤ backup time < 3 h, EOD is 1.75 V/cell.
3.
If backup time ≥ 3 h, EOD is 1.80 V/cell.
