High-Precision Lithium Battery Internal Resistance Meter Tester

Ultra-Accurate 4-Line Measurement
Professional-grade 4-wire Kelvin sensing eliminates lead resistance interference, delivering lab-level precision (±0.5%) for lithium battery R&D, quality control, and maintenance.
Robust Aerospace-Grade Build
Military-grade aluminum alloy casing with anti-slip silicone grips and scratch-resistant OLED display ensures durability for workshop, fieldwork, or factory use.
Fast Multi-Battery Compatibility
Tests all lithium chemistries (Li-ion/LiPo/LiFePO4) from 18650 to EV packs (0-1000mΩ range) with auto-calibration and 0.1mΩ resolution.
Engineered for Efficiency
Integrated 5000mAh rechargeable battery provides 200+ tests per charge, while the magnetic backplate allows hands-free operation on metal surfaces.
Data-Driven Maintenance
Identifies aging cells (resistance >50mΩ) in solar banks, RC drones, and electric vehicles—critical for preventing thermal runaway in high-drain applications.
Global Compliance Ready
CE/FCC/RoHS certified with IP54 splash resistance, meeting EU/US safety standards for professional and industrial use.
Wholesale Advantage
Direct-from-factory pricing with bulk discounts for labs, recyclers, and battery distributors—no middlemen, pure cost savings.
