Every battery system is only as strong as its weakest link. Capacity testing shows how well the system holds charge over time. Cell voltage monitoring finds the weak link.

Manual cell-by-cell measurements are slow and prone to human error, especially in long discharge tests. Automatic measurement records every cell voltage throughout the test, so results stay consistent and weak cells are caught early.

DV Power’s BVS and BVS-4 battery supervisors automate this process. Combined with the BLU-C and BLU-D series, they measure capacity and cell voltages simultaneously. Every cell voltage is logged for the full duration of the test, so you have a complete record to review afterwards. This integrated system improves data accuracy, speeds up decision-making, and makes battery maintenance more efficient.

Even simpler than with the BLU-A and BLU-T, the BLU-C and BLU-D series have the BVS Control Unit built in, so there is no need for a separate unit or DV-B Win software. Monitoring is possible directly from the touch screen display.

Ideal for stationary batteries in substations, data centers, and industrial backup systems.
