Battery Charge / Discharge Test Systems
Professional battery cyclers for R&D, QC and production — accurate, repeatable and built for continuous 24/7 operation.
Battery Cycler
Precision Charge/Discharge Testing for Every Cell Chemistry
The VT-CDS series is VoltTest's flagship battery cycler family. Each channel runs independently with CC, CV, CP and CR modes, making it the ideal battery testing equipment for cycle life studies, rate capability tests, calendar aging and battery modelling.
- ✓ Independent channels: 8 / 16 / 32 per 19-inch rack
- ✓ Voltage ranges 0–5 V, 0–10 V, 0–60 V, 0–200 V
- ✓ Current from 1 mA to 300 A per channel
- ✓ ±0.05% FS accuracy, 1 ms data logging
- ✓ Regenerative discharge: ≥90% energy recovery

Key Features
Engineered for the Battery Laboratory
High Accuracy
16-bit ADC, four-wire Kelvin sensing and calibrated references deliver ±0.05% FS voltage and current accuracy.
Fast Sampling
1 ms data logging captures voltage, current, power and internal resistance dynamics during pulse testing.
Energy Recovery
Regenerative discharge feeds ≥90% of energy back to the grid, reducing heat and operating cost.
VoltTest Studio
Graphical test programming, cycle statistics, database export, and MES/ERP integration for traceable data.
Multi-Channel
Up to 32 independent channels per rack, expandable to hundreds of channels in one test bench.
Safety Interlocks
Over-voltage, over-current, over-temperature protection and alarm chain per channel.
