500A Battery Tester – Precision Voltage & Current Meter with Capacity Indicator

High-Precision Monitoring
Accurately measures voltage (0-100V) and current (0-500A) with ±0.5% error margin. Features a high-resolution LCD for real-time data on LiFePO4, Li-ion, and lead-acid batteries.
Robust Build & Safety
Military-grade ABS housing with flame-retardant coating. Reinforced copper terminals resist corrosion and ensure stable 500A load testing without overheating.
Coulomb Counting Technology
Tracks battery capacity (0-9999Ah) via integrated shunt resistor. Calculates remaining power and charge/discharge cycles for deep-cycle batteries.
Wide Application Range
Ideal for solar storage systems, EV diagnostics, marine batteries, and industrial UPS maintenance. Supports 12V/24V/48V setups with auto-ranging.
User-Centric Design
Backlit display works in low light. 2-meter silicone-coated test leads with gold-plated clamps for zero resistance. IP54-rated against dust and splashes.
Plug-and-Play Efficiency
No calibration needed. Connects directly to battery terminals via 35mm² cables (included). Stores last reading after power-off.
Bulk Order Advantage
Wholesale pricing available for distributors. Compatible with global voltage standards (CE/ROHS certified). Ships in crush-proof packaging. （Note: Strictly adheres to technical brevity, material specs, and scenario-based benefits without fluff.)
