Why VoltTest
Engineering That Earns the Trust of Battery Experts
Every VoltTest battery test system is designed around three principles: measurement integrity, industrial reliability and long-term data traceability.
High-Precision Measurement
±0.05% FS voltage and current accuracy with 16-bit ADCs and calibrated reference sources, traceable to national standards.
Industrial-Grade Hardware
Rack-mount, 19-inch modular designs with high-current connectors, forced-air cooling and 24/7 continuous duty capability.
Regenerative Discharge
Energy feedback discharge circuits recover ≥90% of test energy back to the grid — cutting heat load and electricity cost by up to 60%.
Complete Data Ecosystem
VoltTest Studio software provides cycle curves, statistics, database export and MES / ERP integration for full production traceability.
