AILI-041 High Precision Battery Coulometer - 8-100V 50-500A Digital Battery Monitor for Voltage/Current/Capacity/PowerProduct DescriptionMeet the AILI-041 Battery Coulometer—your professional-grade solution for precise battery monitoring, designed to keep you in full control of your power systems! Whether you’re powering an RV, solar energy system, fishing boat, or backup power setup, the AILI-041 delivers real-time, accurate data to protect your batteries and optimize performance.Boasting an impressive ±1% accuracy class, this coulometer monitors a comprehensive range of battery parameters: voltage (8-100V DC), current (50-500A), capacity (0-9999.99Ah), power (0-50KW), total charged/discharged energy (up to 99999.99kWh), SOC (state of charge), SOH (state of health), charge/discharge time, and cycle count (up to 9999 times). Compatible with lithium batteries, it’s the ideal tool for tracking battery health and preventing damage from overcharging, deep discharge, or abnormal current/voltage.Equipped with multi-layer protection, the AILI-041 features automatic alarms for overvoltage, overcurrent, and overtemperature—keeping your batteries and equipment safe. Opt for an optional external temperature probe (sold separately) to monitor battery temperature directly, outperforming ordinary monitors that only track ambient temperature. Its IP-rated waterproof and dustproof design, with an internal rubber gasket and 3M waterproof adhesive film, ensures reliable performance in outdoor or harsh environments, resisting daily splashes, dust, and moisture.Installation is hassle-free with the included accessories: shunt, 2m USB cable, and 2m OT8 cable. The compact size (88×49×21mm) fits easily into tight spaces, making it perfect for RV/camper van life, solar power systems, fishing boats/ vessels, backup power setups, and electronic projects. Backed by a 3-month warranty and built with high-quality components, the AILI-041 is trusted by users worldwide for its consistent performance and long-lasting durability. Whether you’re a DIY enthusiast or a professional, this coulometer takes the guesswork out of battery management.
