Foxwell BT705 PLUS+Foxwell BT630

• 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 efficien
• Comprehensive Safety Protection: Constructed with high-strength, heat-resistant fiberglass housing to prevent accidental electric shocks. Honeycomb ventilation paired with an advanced temperature sensor ensures optimal thermal management and efficient operation. The dedicated app integrates 8-layer safety protect for customizable alerts and power cutoff (requires external relay), including over/under-voltage, charge/discharge overcurrent, overpower, over-temperature, low-temperature, and low SOC
• Dual-Calibration Precision: Inaccurate battery level displays have long been a user concern. Foxwell's automatic error calibration resolves this by leveraging a long-term model database to autonomously adjust readings, eliminating battery anxiety. The built-in high-precision shunt (±0.4% error) significantly reduces manual calibration frequency.Whether for short commutes or long road trips, it precisely calculates power consumption, predicts battery health status, and helps plan usage schedules
• 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: Monitori
• Long-Term Tracking, No Guessing: Imagine driving your beloved car on a remote mountain road when sudden abnormal battery alerts strike – BT630's visualized data graphs detect hidden risks 30 days in advance. Monitor current, voltage, and temperature trends during off-road adventures to preempt failures, avoiding breakdowns in isolated areas and paid costly repair bills.
