Wireless RV and Caravan Smart Battery Monitor with Bluetooth App and 500A Smart Shunt

Take full control of your off-grid power system with this advanced wireless smart battery monitor, designed for RVs, caravans, campers, and solar setups. Monitor your battery performance in real time, prevent unexpected power loss, and maximise battery life with precise data and intelligent tracking.

A smart battery monitor uses a high-precision shunt to measure energy flow in and out of your battery, allowing you to accurately track usage, remaining capacity, and overall battery health .

This system is ideal for lithium battery setups, where voltage alone isn’t enough to determine remaining charge. With real-time data and app connectivity, you’ll always know exactly how much power you have left.

Key Features

Real-Time Battery Monitoring

Track critical battery data including voltage, current, power consumption, state of charge (SOC), and remaining capacity directly from your smartphone. Smart shunt systems calculate energy usage by measuring current flow in and out of the battery .

Bluetooth App Connectivity

Connect wirelessly via Bluetooth to monitor your battery from your phone. View live performance data, historical usage, and system status anytime.

High Precision 500A Smart Shunt

Built for high-demand RV and caravan systems, the included shunt accurately measures current flow up to 500A, making it perfect for lithium battery banks and off-grid setups .

Supports Multiple Battery Types

Compatible with lithium (LiFePO4), AGM, gel, and lead-acid batteries, making it suitable for a wide range of setups and upgrades.

State of Charge (SOC) Accuracy

Unlike basic voltage meters, this system calculates true battery capacity and remaining runtime, helping you avoid unexpected power loss on the road.

Advanced Battery Data

Monitor key performance metrics including:

• Voltage
• Current (Amps)
• Power (Watts)
• State of Charge (%)
• Remaining time
• Cycle count and battery health

Improves Battery Lifespan

By monitoring usage and preventing overcharging or deep discharging, a battery monitor helps extend battery life and improve overall system efficiency .

Wide Voltage Compatibility

Supports 12V, 24V, and 48V systems, making it ideal for caravans, motorhomes, solar systems, and 4WD dual battery setups.

Easy DIY Installation

Simple installation with included shunt and wiring harness. Mount in your battery system and connect to your phone in minutes.
