Smart 12V-80V 500A Bluetooth Battery Shunt Monitor with App Data Logging for RV, Marine & LiFePO4 Off-Grid Systems

GFL Tech™ Smart 12V-80V 500A Bluetooth Battery Shunt Monitor

Stop guessing how much house battery power you have left. Designed for RVs, camper vans, marine vessels, and off-grid solar setups, this heavy-duty 500A smart battery shunt measures real-time current, voltage, remaining capacity (Ah), and state-of-charge (SOC). Integrated Bluetooth 5.0 streams precision battery health analytics and historical trend logs straight to your smartphone.

Why DIYers & Rig Builders Choose This Shunt

• Precision High-Current Monitoring: Includes a heavy-duty 500A brass shunt with ±1% current and voltage accuracy, ensuring reliable measurement under heavy inverter loads or high-amp alternator charging.

• Real-Time Bluetooth App Tracking: Syncs instantly via the mobile App (iOS/Android) to monitor instant watts, current draw, time remaining, and historical discharge cycles—no bulky dashboard cutout required.

• Ultra-Wide Voltage Compatibility: Operates natively from 8V to 80V DC, making it fully compatible with 12V, 24V, 36V, and 48V battery banks.

• Universal Battery Chemistry Support: Fully programmable parameters for LiFePO4 (Lithium Iron Phosphate), AGM, Gel, and Flooded Lead-Acid battery chemistry setups.

• Ultra-Low Power Draw: Consumes only 1-2mA in standby, preventing parasitic battery drain during seasonal storage.
