High-Precision Battery Testing
The ET5410A+ and ET5420A+ deliver lab-grade accuracy with 0.05% resolution for voltage and current, ensuring reliable performance validation for lithium-ion, lead-acid, and NiMH batteries.
Dual-Channel Versatility
Simultaneously test two batteries with independent control, featuring 0-60V/0-30A per channel—ideal for R&D labs, production lines, and quality assurance in EV or solar storage systems.
Dynamic Load Simulation
Patented constant current/resistance/power modes mimic real-world drain scenarios, from smartphones to industrial UPS backups, with programmable step loading up to 500Hz.
Enhanced Thermal Design
Aircraft-grade aluminum housing with CNC-machined cooling fins maintains stable operation at 95% load capacity, backed by silent dual-ball-bearing fans.
Smart Data Management
Export CSV via USB or Bluetooth to analyze discharge curves, capacity fade trends, and internal resistance—compatible with LabVIEW and Python scripts.
Global Compliance Ready
CE/FCC/RoHS certified with universal 100-240V AC input, deployable in OEM factories, repair centers, or field service kits worldwide.
Bulk Purchase Advantage
Direct-from-factory pricing cuts middleman costs by 40%, backed by 24/7 technical support and same-day shipping for wholesale orders.
