0-600A Smart Battery Monitoring: The FOXWELL BT630 monitors currents up to 600A, so you can safely run high-demand loads like RV air conditioners, industrial inverters, and electric boat propulsion without worrying about overloads or shutdowns. It displays real-time voltage, current, power, battery level, temperature, and remaining runtime, helping you stay on top of system health during peak usage. Designed for RVs, boats, EVs, solar panel, industrial systems, home/medical backup systems, emergency power and off-grid Cabins, it supports 10–120V lead-acid, lithium-ion, NiMH, and solar batteries. Bluetooth and the app let you view critical data without climbing into cramped compartments
Precision Auto Calibration: When you rely on your battery monitor to plan power use or avoid outages, accuracy matters. This battery monitor 12v uses a ±0.4% high-accuracy shunt and automatic calibration to ensure stable readings over time—without drift or guesswork. Whether you're deciding if your RV battery can keep the A/C running until morning, or checking if your off-grid solar system has enough charge to last through a cloudy weekend, precise readings help prevent surprises, shutdowns, and early battery failure. No more recalibrating or second-guessing your battery status
Smart Alerts & Protection: Battery issues often go unnoticed until swelling, deep discharge, or permanent damage has already set in. The lithium battery monitor provides eight layers of built-in protection with customizable alerts through the app, instantly notifying you if voltage drops, temperatures spike, or overcurrent occurs. Whether your boat is docked under the sun or your cabin system is quietly draining during an outage, early warnings help you take action before things go wrong. A built-in temperature sensor and heat-resistant housing ensure safe, reliable performance—even in harsh conditions
Ultra-Low Power 0.4W: Traditional 12v battery monitor consume more power than they save, especially in systems left idle for weeks. The BT630 is designed differently. With just 0.4W of power draw, it runs 3 to 10 times longer than typical models without draining your battery. A 12V 200Ah battery can support over 200 days of continuous monitoring under ideal conditions. Whether your RV is stored for the season or your solar backup is waiting for an outage, the BT630 keeps monitoring silently—so you won't return to find your battery drained by the monitor itself. Note: Monitoring duration is based on lab conditions and may vary in actual use
Easy to Set Up: The lifepo4 battery monitor battery monitor is designed to make setup simple. Clearly labeled terminals help prevent wiring errors, and the included shielded 4P and 3P cables reduce interference from nearby inverters or high-current devices. Installation pictures and video tutorials on the product page, along with QR codes in the box and manual, let you access guides anytime—even while working in tight spaces or remote locations. If you have questions, our support team is ready to assist, so you can complete installation with confidence. Tip: Initial setup is easy. Just follow the steps provided
RS-485 Communication Interface: Enables long-distance, stable data transmission, supporting up to 99 devices. It integrates with display screens for clear, real-time visualization and provides raw device data access via RS-485 for advanced customization. Smart functions wirelessly share real-time battery data to ensure safe, efficient charging. Designed for easy retrofitting, it seamlessly integrates into existing smart shunt battery monitoring systems
