Expion360 Lithium Battery Monitor Kit with Shunt (BM350) – High Precision LiFePO4 Fuel Gauge | Expion360

Take the Guesswork Out of Your Power Supply Stop relying on vague voltage lights. The Expion360 EX-BM350-KT is a high-precision battery monitor designed specifically for the unique discharge curve of LiFePO4 lithium batteries. Whether you are boondocking in an RV or off-grid in a marine environment, this "fuel gauge" provides the ultimate peace of mind.

Why the BM350 is Essential for Your Lithium Setup:

  • Real-Time Accuracy: Unlike standard monitors, the included high-accuracy shunt measures the actual current flowing in and out of your battery bank.

  • State of Charge (SOC): View your remaining battery capacity as a percentage (0% to 100%), so you know exactly how much "juice" is left in your Expion360 batteries.

  • Comprehensive Data: Track voltage, current (Amps), power (Watts), and remaining amp-hours at a single glance on the backlit LCD.

  • Universal Compatibility: Optimized for 12V, 24V, and 48V systems, making it the perfect companion for the Expion360 LiFePO4 Lithium Batteries

The Complete Kit Includes:

  • High-precision LCD Monitor

  • 500A Shunt (Handles high-surge loads with ease)

  • Shielded data cable for interference-free communication

  • Clear installation hardware for a professional-grade finish

Included: 

  • Battery Monitor display screen
  • Brass power measuring shunt
  • 35 ft data cable (connects shunt to screen)
  • Aluminum shunt bracket
  • Small, 22-gauge positive power wire
