GRUNDIG WiFi Battery Coulomb Meter - Up to 60KW / 600A Wireless Remote Battery Capacity Monitor with App, 2.4" Color Display, Bidirectional Current Detection for Lead-Acid LiFePO4 Lithium Batteries

GRUNDIG WiFi Battery Coulomb Meter with App Remote Monitoring - 2.4" Color Display, Bidirectional Current Detection, Smart Alarm, Power-Off Memory - 105F/110F/140F/160F (50A to 600A)

Meet the GRUNDIG WiFi Battery Coulomb Meter -- your battery's smart manager. This advanced wireless monitor gives you real-time voltage, current, power, remaining capacity (Ah & percentage), and estimated charge/discharge time, all directly on your smartphone from anywhere in the world.

Unlike a simple voltmeter, the GRUNDIG coulomb meter measures actual energy flow in and out of your battery with high precision (voltage accuracy +/- (5 per thousand + 0.02V), capacity tracking down to 0.001Ah). Whether you are charging or discharging, the bidirectional sensor automatically detects the direction and updates every parameter instantly.

Key Highlights at a Glance:

• Triple connectivity: Bluetooth (nearby) + WiFi LAN + Cloud remote (worldwide)
• 2.4-inch HD color LCD with dark/light dual display modes for any lighting condition
• Bidirectional current detection -- auto-switches between charging (A+) and discharging (A-)
• Full parameter readout: voltage, current, power, Ah, percentage, estimated time remaining
• Smart alarm: low voltage + low capacity alerts with buzzer + pop-up (thresholds adjustable via app or display)
• Power-off memory: saves all settings automatically, restores on reconnection
• All-copper shunt with protective housing for superior conductivity, low heat, and safe installation
• Dedicated mobile app with animated charging UI, full parameter control, and multi-device management (Junce Home platform)
• Compatible with lead-acid, ternary lithium (NMC), LiFePO4, and other batteries within 10-100V range

One-Liner Summary

"Check your battery status anytime on your phone -- know every charge and discharge at a glance. The smart battery manager for your RV."

What's in the Box

The Problems We Solve

Still guessing your battery level? The GRUNDIG WiFi Coulomb Meter eliminates the most common battery frustrations:

• Stranded with a dead battery mid-ride: No more vague estimates. See your exact remaining capacity and estimated run time so you always know when to recharge.
• Dashboard lies after battery upgrades: Swapped to a bigger battery or converted your ride? Factory gauges become unreliable. Get true, calibrated readings.
• Charging in the dark: Watching a battery charger with no feedback? The coulomb meter shows charge progress in real time -- you will know exactly when it is full.
• Range anxiety wherever you go: Camping off-grid, cruising on a boat, or hauling gear in your RV -- check your battery from your phone without leaving your seat.

GRUNDIG turns guesswork into knowledge.

Detailed Features

1. WiFi + Bluetooth + Cloud Remote -- Triple Connectivity Connect three ways depending on your needs: Bluetooth for quick nearby checks (works without internet), WiFi LAN for local network access, and Cloud remote for worldwide monitoring from anywhere with an internet connection. The dedicated mobile app keeps you in the loop whether you are inside the RV or a thousand miles away.

2. 2.4-Inch HD Color LCD with Dual Display Modes Bright, clear color screen showing voltage, current, power, remaining capacity (Ah), percentage, and estimated time remaining. Switch between dark mode (default) and light/white mode for optimal readability in direct sunlight or low-light conditions.

3. High-Precision Full-Parameter Measurement Goes far beyond voltage alone:

4. Smart Adjustable Alarm System Never over-discharge your battery again. Set your own low-voltage and low-capacity thresholds via the mobile app or directly on the display unit. When triggered, the built-in buzzer sounds and an on-screen pop-up alert appears -- giving you both an audible and visual warning.

5. Intelligent Power-Off Memory Built-in storage chip preserves all settings and accumulated data during unexpected power loss. When power is restored, the meter automatically resumes operation with your previous configuration. No need to re-enter parameters after every shutdown.

6. All-Copper Hardware with Protective Housing High-purity copper shunt and copper terminal screws deliver low electrical resistance, minimal heat generation, and ultra-low standby power consumption (barely any drain on your battery). The shunt comes with a protective housing for safe, easy installation and effective heat dissipation.

7. Powerful Mobile App (Junce Home Platform) The companion app features a newly designed dynamic interface with animated charging visuals. Beyond real-time monitoring, you can:

• Configure full battery capacity
• Set alarm thresholds for voltage and capacity
• Adjust screen brightness and auto-off time
• Manage multiple GRUNDIG devices from one dashboard
• View historical data and trends

Compatible with both iOS and Android.
