TK15 Coulomb Meter & Battery Capacity Tester

Monitor your power systems with industrial precision using the TK15 Coulomb Meter, a high-fidelity battery capacity tester engineered for high-demand electrical environments. Designed to provide real-time data for vehicles, this battery coulometer accurately tracks energy flow, ensuring you never miscalculate your remaining range. Whether installed in an E-bike, balance car, or cleaning machine, this device offers a comprehensive view of your battery's health and performance.

Key Features

• Universal High-Voltage Support: Engineered to handle systems up to 120V, making it compatible with a wide array of battery chemistries including Lithium and Lead-Acid.

• High-Precision Coulomb Counting: Utilizes advanced coulomb meter technology to measure actual current flow (Ah) for a much more accurate reading than standard voltage-based meters.

• Versatile Current Ratings: Available in 50A, 100A, and 350A configurations to match the specific power requirements of your cleaning machine or custom EV.

• Multifunctional LCD Display: Provides clear, high-fidelity readouts of voltage, current, power, and remaining battery capacity percentage at a glance.

• Vehicle-Grade Durability: Built to withstand the vibrations and environmental demands of balance cars and E-bikes, ensuring long-term reliability.

Why Choose This Professional Coulometer

Standard voltage meters are notoriously inaccurate, as voltage "sags" under load; our TK15 Coulomb Meter is optimized for high-fidelity accuracy by measuring every milliampere that enters or leaves the battery. The dedicated shunt design is a critical functional upgrade, allowing for safe monitoring of high-current systems in an E-bike or cleaning machine without overheating. Unlike basic battery indicators, this battery capacity tester provides a professional-grade "fuel gauge" experience for your electric vehicle. By choosing this precision instrument, you are investing in a durable tool that protects your battery from deep discharge and improves operational safety.

Perfect For

• E-bike & Electric Scooter Upgrades: Get an exact percentage of your remaining battery life to plan your trips with confidence.

• Industrial Cleaning Machines: Monitor the discharge cycles of floor scrubbers and industrial sweepers to optimize maintenance schedules.

• Custom EV & Solar Projects: The ideal coulomb meter for hobbyists building high-voltage battery banks or balance cars.
