Compact Color Screen Lithium Battery SOC Monitor TC169 with Multi-Parameter Display

The TC169 is a compact color screen lithium battery SOC monitor engineered for precise real-time monitoring of lithium battery packs. Featuring a 1.69-inch TFT color display, this monitor presents battery state of charge (SOC), voltage, current, and power simultaneously on a single screen, eliminating the need to toggle between readings. The compact design allows direct surface mounting on battery packs used in electric scooters, electric motorcycles, portable power stations, and backup battery systems, making it a practical solution for battery pack power monitoring in space-constrained installations.

One common issue with low-cost battery monitors is SOC readings that jump erratically between charges. The TC169 uses impedance tracking algorithms combined with coulomb counting to deliver stable and accurate lithium battery SOC monitoring across the full 0.1-999Ah detection range. With ±1% accuracy on voltage, current, and capacity measurement, the TC169 provides reliable battery status data that users can trust for their lithium iron phosphate (LiFePO4), lithium-ion, and other lithium battery packs. The multi-parameter simultaneous display shows SOC percentage, real-time voltage, current draw, and remaining capacity on one compact color screen, enabling quick at-a-glance battery health assessment.

• Compact 1.69-inch color screen fits directly on battery pack surfaces without adding bulk
• Stable SOC readings using coulomb counting with impedance tracking to prevent erratic value jumps
• Multi-parameter simultaneous display shows SOC, voltage, current, and capacity on one screen
• Wide 8-90V input range compatible with various lithium battery pack configurations
• Three shunt options (30A, 50A, 100A) to match different battery pack current requirements
• Four-button operation with selectable simplified or standard interface modes
• Optional membrane keypad version with front splash and water resistance for outdoor use
• Customizable UI interface and communication protocol for OEM integration

This compact color screen lithium battery SOC monitor is designed for lithium battery pack power monitoring in applications including:

• Electric scooter and electric motorcycle battery packs
• Portable power stations and backup battery systems
• DIY lithium battery pack projects (LiFePO4, Li-ion)
• Small-capacity energy storage battery systems
• Recreational vehicle and marine auxiliary battery monitoring

Q: Does the TC169 work with different lithium battery chemistries?

The TC169 is compatible with mainstream lithium battery types including LiFePO4, lithium-ion, and lithium polymer batteries. The SOC monitoring algorithm can be calibrated for the specific discharge curve of your battery chemistry to ensure accurate readings.

Q: How does the TC169 prevent SOC readings from fluctuating?

The TC169 uses a combination of coulomb counting and impedance tracking to deliver stable SOC measurements. Unlike basic voltage-only monitors that show erratic percentages, the TC169 continuously tracks energy in and out of the battery pack and cross-references with voltage characteristics to provide consistent readings across the full charge-discharge cycle.

Q: What parameters are shown on the multi-parameter display?

The compact 1.69-inch color screen displays battery SOC percentage, real-time voltage, current draw (amps), power (watts), and remaining capacity (amp-hours) simultaneously. Users can choose between a simplified interface with essential data or a standard interface with comprehensive parameters.

Q: How is the TC169 installed on a lithium battery pack?

The TC169 features a compact form factor measuring 58.4 x 40.4 x 9.6mm and can be surface-mounted directly on battery packs. The rear-mounted 30A shunt option allows direct integration behind the display for maximum space efficiency.
