TC147 Compact Color Display High Precision Lithium Battery Monitor 8-80V 0-150A

TC147 Compact Color Display Lithium Battery Monitor Overview

The TC147 is a compact lithium battery monitor equipped with a 1.47-inch color TFT LCD screen, purpose-built for high-precision monitoring of LiFePO4, lithium-ion, and other lithium battery packs. It delivers ±1% measurement accuracy for voltage (8-80V DC) and current (0-150A via external shunt), with capacity detection spanning 0.1 to 999Ah. The miniaturized design measures just 52.4*29.4*9.4mm and requires a panel cutout of only 48*26.5mm, making it ideal for space-constrained lithium battery system installations.

The color display presents voltage, current, and capacity percentage on a single interface, enabling quick status assessment of lithium battery packs. Powered directly from the monitored battery circuit, the TC147 high precision monitor operates reliably across a -10°C to 50°C temperature range.
