TC147 Shunt Based Battery Monitor 1.47 Inch Color Screen 8-80V DC 0-150A

TC147 Shunt Based Battery Monitor Overview

The TC147 is a shunt-based battery monitor featuring a 1.47-inch color TFT LCD screen, designed for real-time monitoring of small battery packs. It measures working voltage from 8V to 80V DC and current from 0 to 150A via an external shunt, with ±1% measurement accuracy. The capacity detection function supports a range from 0.1Ah to 999Ah, making it suitable for various battery pack configurations across 12V to 72V systems.

With compact dimensions of 52.4*29.4*9.4mm and a panel cutout requirement of only 48*26.5mm, the TC147 integrates easily into tight instrument panels. The 1.47-inch color screen presents voltage, current, and capacity percentage on a single interface for quick status assessment.

Technical Specifications

Key Features and Advantages

• Shunt-Based Current Measurement with ±1% Accuracy: The TC147 shunt based battery monitor employs an external current shunt for stable and reliable data acquisition across the full 0-150A range. This measurement method delivers consistent ±1% accuracy for both voltage and current readings, ensuring dependable battery status tracking for small pack applications.
• 1.47-Inch Color LCD Display for Clear Multi-Parameter View: The vibrant 1.47-inch color screen clearly presents voltage, current, and capacity percentage readings simultaneously. The color-coded interface improves data legibility compared to monochrome meters, allowing operators to quickly assess battery conditions including charge level and current draw.
• Wide 8-80V DC Voltage and 0-150A Current Range: Covering battery pack voltages from 12V through 72V, the TC147 accommodates common configurations in small energy storage, mobility, and backup power systems. The 0.1-999Ah capacity detection range ensures compatibility with various battery capacities within these voltage and current limits.
• Compact Panel-Mount Design for Space-Constrained Installations: With a slim 9.4mm depth and minimal 48*26.5mm panel cutout, the TC147 battery monitor fits into tight dashboard and control panel spaces where larger meters cannot be accommodated. The 52.4*29.4mm front face maintains a clean, professional appearance.

Typical Applications

• Small Solar Energy Storage Systems: Monitor 12V or 24V battery banks in off-grid solar setups. The shunt-based current measurement tracks charging and discharging currents, while the capacity display helps users manage energy consumption and charging schedules.
• Electric Scooters and E-Bikes: Suitable for 24V, 36V, and 48V battery packs in personal electric vehicles. The 1.47-inch color screen fits within compact dashboard spaces, displaying remaining capacity and real-time current draw during operation.
• UPS and Backup Power Systems: Track backup battery status in small uninterruptible power supplies. The capacity percentage display provides clear indication of remaining runtime, and the compact dimensions allow integration into UPS front panels.
• Golf Cart and Mobility Vehicle Battery Packs: Monitor 36V or 48V traction battery systems. The 0-150A current range covers typical cruise and peak currents for golf carts and mobility scooters, while the color display is easy to read in outdoor cabin environments.

Frequently Asked Questions

Q: What battery voltages does the TC147 shunt based battery monitor support?
A: The TC147 operates within an 8-80V DC working voltage range, covering common configurations from 12V to 72V systems. The unit is powered directly from the monitored battery circuit.

Q: How is the external shunt connected for current measurement?
A: The external current shunt connects in series on the negative side of the battery circuit. The TC147 measures the voltage drop across the shunt to calculate current flow within the 0-150A range. The shunt is included with the unit.

Q: How do I configure the battery capacity setting?
A: Navigate to the capacity setting menu using the front-panel buttons, enter your battery pack's rated ampere-hour value within the 0.1-999Ah range, and confirm. The monitor uses this value as the reference for capacity percentage calculation.

Q: Can the TC147 monitor multiple battery packs at once?
A: Each TC147 unit monitors one battery pack. For systems with multiple independent banks, install separate units per pack. The compact 52.4*29.4mm footprint allows side-by-side panel mounting of multiple units.
