FOXWELL BT630 Battery Monitor with Shunt, 10-120V up to 600A

FOXWELL BT630 Battery Monitor with Shunt, 10-120V up to 600A with Time Capacity Percentage Power Amps Volt, High and Low Voltage Alarm for RV/Marine/Motorcycle/Solar Panel

Real-Time Bluetooth Monitoring: FOXWELL BT630 seamlessly integrates with BMS apps via stable Bluetooth connectivity, supporting high-current monitoring up to 600A and wide voltage range tracking from 10V to 120V. It displays 9 critical metrics in clear graphs: SOC%, Voltage, Current, Remaining Capacity, Power, Temperature, Estimated Runtime, and Charge/Discharge History. Designed for RVs, EVs, marine systems, off-grid setups, portable power stations, and outdoor devices, it ensures peak efficiency for Lead-Acid, Li-ion, Ni-MH, and Solar batteries. Tip: The maximum unobstructed Bluetooth range is 32.8 feet
Comprehensive Safety Protection: Built with high-strength, heat-resistant fiberglass housing to prevent accidental electric shocks. Honeycomb-style ventilation and a smart temperature sensor ensure efficient heat dissipation and stable performance. The companion app offers 8-layer protection with customizable alerts and optional auto power cut-off for over/under-voltage, charge/discharge overcurrent, overpower, high/low temperature, and low SOC. This prevents battery swelling from overcharging and protects against deep discharge—extending battery lifespan Tip: Auto power cut-off function requires an external relay (sold separately)
Dual-Calibration Precision: Inaccurate battery level displays have long been a user concern. Foxwell's automatic error adjustment resolves this by leveraging a long-term model database to autonomously adjust readings, eliminating battery worries. The built-in high-precision shunt (±0.4% error) significantly reduces manual adjustment frequency. Whether for short commutes or long road trips, it precisely calculates power consumption, predicts battery health status, and helps plan usage schedules and maintenance cycles Note: Initial setup requires simple configuration of battery capacity, full-charge voltage, tail current, and full-charge detection time
Low Power, Last Longer: Traditional battery monitors often drain your batteries? The BT630's ultra-low 0.4W power consumption design extends runtime for your RV/solar/storage batteries 3-10 times longer than other products on the market. You can focus more on enjoying your journey or work without worrying about low battery. A 12V 200Ah RV battery can continuously monitor for 200+ days under BT630's average power consumption. Charge less and enjoy more efficient battery management! Note: Monitoring days are theoretical values based on a fully charged battery and no-load conditions, and may vary with actual usage
Long-Term Tracking, No Guesswork: Imagine driving on a remote mountain road when BT630’s clear data graphs alert you to battery issues 30 days in advance. You can monitor current, voltage, and temperature trends during off-road adventures to prevent unexpected breakdowns in isolated areas. This helps keep you safe and avoid costly repairs
Plug and Play Installation: Designed for hassle-free setup, the BT630 features a user-friendly shunt base with clearly labeled negative terminals (battery/load) under the cover. Shielded 4P/3P cables make wire identification quick and easy, eliminating complex wiring. Step-by-step diagrams and video tutorials guide even first-time users through a seamless installation
RS-485 Communication Interface: Enables long-distance data transmission. Supports integration of a display screen for data visualization. Accesses raw device data through the RS-485 interface to meet secondary development requirements, and allows communication with up to 99 devices simultaneously. Implements smart functions and optimizes charging by wirelessly sharing real-time battery data with other devices in the system. Features easy installation and supports retrofit integration into existing systems

From the brand

In 2024, FOXWELL engineers witnessed a traveler stranded in the Alaskan aurora at an RV campsite—his solar system, capable of three days' power, lay useless due to battery over-discharge. That night revealed our epiphany: true energy freedom begins with precise mastery over every milliamp. Thus began FOXWELL's technological odyssey in precision energy management, guided by our "current microscope" philosophy.
