CGELE Battery Monitor DC Multifunction 0–200V/0–300A with External Shunt, Backlit LCD for Cars RV Solar

The CGELE DC Multifunction Battery Monitor is a compact panel meter with an external shunt that measures voltage, current, power and nine other battery parameters for 12V/24V/48V systems.

This digital monitor consolidates multiple battery metrics onto a full-view backlit LCD so you can track battery state and energy flow at a glance. Designed for cars, RVs, marine, and off-grid solar installations, it combines a high-precision measurement chip with an easy press-terminal wiring design and an external shunt for safe high-current sensing. The unit reads voltages up to 200V and currents up to 300A and reports calculated values such as power, capacity, SOC and accumulated energy.

How does this meter display and organize nine parameters for quick checks?

The CGELE monitor cycles or pages through nine key readings on a single interface so you don’t need multiple instruments. The full-view LCD with backlight offers clear visibility day or night and supports 360° viewing to reduce blind spots.

• Displays Voltage (0–200V) and Current (0–300A) on one screen.
• Shows Power (0–60000W), Energy (0–9999kWh) and Running Time (0–999h).
• Reports Impedance, Internal Resistance, Capacity (0–1000AH) and SOC.
• Backlit, wide-angle LCD for easy reading in all lighting conditions.

How accurate and reliable are the measurements for battery management?

The meter uses a high-precision control chip and a stable welding process to deliver repeatable readings with an accuracy around 1%. An external shunt isolates high-current sensing from the display electronics for safety and long-term stability.

• Measurement accuracy approximately 1% for consistent monitoring.
• External shunt handles up to 300A to protect the meter electronics.
• Solid manufacturing and reliable connections reduce drift over time.
• Measures internal resistance and impedance to help assess battery health.

Is installation difficult and what connections are required?

Installation is designed to be straightforward: press-terminals remove the need for screws and simplify wire insertion and removal. The external shunt connects in series with the negative line, while the meter’s low-voltage sensing leads and power supply complete the setup.

• Press-terminal design—no screwdriver required for wire connections.
• External shunt mounted in-line with the battery negative for current sensing.
• Wiring includes power supply leads, shunt connections and optional sense wires.
• Designed for common battery systems: 12V, 24V and 48V setups.

What systems and use cases is this monitor best suited for?

The CGELE monitor is versatile enough for vehicles, RVs, boats and off-grid solar setups where compact multi-parameter feedback is needed. It’s also useful in industrial prototypes and assembly lines that require voltage/current/power logging without a large footprint.

• Automotive and RV electrical panels for battery and auxiliary load tracking.
• On-grid or off-grid solar installations for energy and SOC monitoring.
• Marine battery banks to check capacity, internal resistance and runtime.
• Light industrial uses where compact, accurate metering is required.

Who is this for: The CGELE DC Multifunction Battery Monitor suits DIYers, RV and marine owners, solar installers, and small commercial users who need a single, accurate display for voltage, current, energy and battery health metrics. If you want a compact panel meter that simplifies wiring, offers wide-angle readable feedback, and supports up to 300A with an external shunt, this unit provides a cost-effective way to keep close tabs on battery performance across 12V, 24V and 48V systems.
