High-Precision 48V DC Battery Discharge Tester with Digital Display

Accurate Voltage & Current Monitoring
Features a high-resolution digital display for real-time voltage, current, and capacity readings with ±0.5% precision. Built with industrial-grade shunt resistors for consistent performance.
Robust Aluminum Alloy Housing
Durable CNC-machined aluminum casing ensures heat dissipation and impact resistance. Anodized finish prevents corrosion in harsh environments.
Adjustable Constant Current Load
Customize discharge rates from 1A to 120A (model-dependent) via rotary encoder. Ideal for testing EV batteries, solar storage systems, and telecom backups.
Multi-Protection Safety Design
Auto-cutoff for over-temperature, reverse polarity, and short-circuit. Thermal fans and heat sinks maintain stability during prolonged use.
Data Logging & PC Connectivity
Export discharge curves via USB for analysis. Compatible with Windows/Linux for fleet maintenance or lab testing.
Global Compliance Ready
CE/RoHS certified. Works with 48V Li-ion, lead-acid, and LiFePO4 batteries. Bulk orders available at wholesale pricing.
