The Electric Battery Capacity Indicator is a battery capacity indicator, battery level indicator, and battery gauge designed to provide a real-time battery indicator display, showing battery charge indicator and battery level meter for accurate power monitoring in different systems.
Precision real-time battery monitoring with full data visibility
- Simultaneously displays voltage (V), current (A), power (W), and remaining capacity (Ah) – giving you a complete real-time snapshot of battery health, charge/discharge status, and overall system performance.
- Calculates estimated remaining runtime (e.g., 02:08:34) based on real-time load, allowing you to schedule usage, avoid unexpected shutdowns, and maximize efficiency during trips or work shifts.
- Supports a wide capacity range from 0.1 to 1000 Ah and works seamlessly with lithium, LiFePO4, lead-acid, AGM, gel, and NiMH batteries – covering everything from small mobility scooters to large off-grid solar storage systems.
- Offers three shunt options (50A/0-75A, 100A/0-150A, 350A/0-500A) with solid copper construction and gold-plated sockets, ensuring high accuracy and low resistance for e-bikes, golf carts, RVs, marine vessels, and industrial forklifts.
User-friendly interface & flexible installation for any vehicle
- Auto-dimming backlight with a built-in ambient light sensor adjusts brightness automatically for clear visibility in sunlight or darkness. You can also switch to manual dimming via front buttons for personalized preference.
- Dual mounting options are included. Choose the snap-in panel mount for dashboards of RVs, forklifts, and yachts. Alternatively, use the handlebar bracket mount for e-bikes, electric scooters, and mobility carts.
- Features a high-color-gamut LCD screen (72.5×20.75 mm) with wide viewing angles. Intuitive menu navigation (PLUS/MINUS, MENU, ENTER/EXIT) makes setup of capacity, alarm thresholds, and voltage points quick and hassle-free.
- The host has a compact size (15×15×5 cm) and a lightweight build (210-420g). It fits tight spaces without adding bulk. Its low-profile design blends seamlessly into any vehicle or equipment dashboard.
IP68 waterproof engineering & intelligent safety protection
- Rated IP68 waterproof and dustproof. It is fully protected against prolonged immersion and fine particles. This makes it ideal for rainy decks, dusty job sites, outdoor RVs, and marine applications.
- Features an adjustable low-capacity alarm with a custom threshold (e.g., 30.0Ah) and instant alerts, helping prevent deep discharge that can damage lithium or lead-acid batteries.
- Equipped with precision copper shunts. The 50A shunt includes an insulated back and protective cover to prevent short circuits. All shunts deliver ultra-low resistance and accurate current sensing for reliable overcurrent protection.
- Consumes only 60-250 mW in standby mode. This minimizes parasitic drain on your battery during idle periods. It is essential for long-term storage, solar installations, and weekend camping trips.

Wiring Method
Q1: What is the Electric Battery Capacity Indicator used for?
A1: The Electric Battery Capacity Indicator is a battery monitor designed to measure and display real-time battery capacity, voltage, current, and state of charge (SOC). It works as a battery gauge and coulometer, helping users clearly understand remaining power, energy usage, and system status. This allows better battery management, prevents over-discharge, and improves overall energy efficiency in daily and industrial applications.
Q2: Which battery systems are compatible with this battery monitor?
A2: This battery capacity indicator supports a wide range of rechargeable battery systems, including lithium batteries, LiFePO4 batteries, lead-acid batteries, and NiMH batteries. It is suitable for both low-voltage and medium-voltage systems and can be used in 12V, 24V, and higher voltage battery setups, making it a flexible solution for various energy storage and power management needs.
Q3: What applications is this battery gauge suitable for?
A3: The device is widely used in RV power systems, marine battery monitoring, electric vehicles, solar energy storage systems, and backup power supplies. It provides reliable SOC battery monitoring and real-time energy tracking, making it ideal for mobile, off-grid, and industrial environments where accurate battery status is critical for system safety and performance.
Tips: How to Choose the Right Electric Battery Capacity Indicator?
- Battery type compatibility. Choose a battery monitor that supports your system, such as a lithium battery, LiFePO4 battery, lead-acid battery, or NiMH battery. Correct compatibility ensures accurate battery capacity indicator reading, stable battery gauge performance, and precise SOC calculation.
- Current range selection. Select an appropriate shunt (50A, 100A, or 350A) based on system load. Low-current systems require smaller ranges, while RV, marine, and industrial systems need higher-range battery monitor configurations for stable battery level indicator and coulometer performance.
- Installation environment. For outdoor, marine, or vehicle applications, IP68 waterproof protection is essential. It ensures the battery capacity indicator operates reliably under vibration, humidity, dust, and temperature changes, maintaining a stable battery level meter and battery gauge performance in harsh conditions.
- Monitoring functions required. Different applications may require different features, such as a battery charge indicator, battery state of charge display, real-time voltage/current monitoring, remaining runtime estimation, and battery level indicator alerts. Choose a battery monitor based on whether basic display or full coulometer functionality is needed.
