bt630 bluetooth battery monitor delivers real-time, high-precision tracking for rvs, evs, marine systems, off-grid setups, and portable power stations, supporting lead-acid, li-ion, ni-mh, and solar batteries. with stable bluetooth connectivity (32.8 ft range), it monitors up to 600a current and 10v–120v (12v/24v/36v/48v/60v/72v/84v/96v/108v/120v) while displaying 9 key metrics—soc%, voltage, current, remaining capacity, power, temperature, estimated runtime, and charge/discharge history—in clear graphs via its dedicated app. engineered for safety, its heat-resistant fiberglass housing and honeycomb ventilation prevent electric shocks, while an 8-layer protection system (over/under-voltage, overcurrent, overpower, temperature extremes, and low soc) ensures safe operation with customizable alerts and external relay cutoff (relay not included). advanced auto-calibration eliminates inaccurate readings using a long-term model database, and its high-precision shunt (±0.4% error) minimizes manual adjustments, providing reliable power consumption tracking and battery health predictions. ultra-low 0.4w power consumption extends monitoring runtime up to 200+ days on a 12v 200ah rv battery (theoretical, no-load conditions), far outperforming traditional monitors. the bt630’s trend analysis detects potential failures 30 days in advance, preventing breakdowns in remote locations. installation is effortless with labeled terminals, shielded cables, and step-by-step guides, while the rs-485 interface enables long-distance data transmission, secondary development, and integration with up to 99 devices for smart charging optimization. designed for adventurers and professionals alike, the bt630 combines precision, safety, and ease of use to eliminate battery concerns and keep your power systems running efficiently. (note: relay and display screen not included. monitoring duration is a reference value under ideal conditions.)
Smart Battery Monitoring at Your Fingertips – The BT630 battery monitor connects via the PRO BMS app to instantly display remaining usage time, SOC, voltage, current, power, temperature, and cumulative charge/discharge. Whether you're powering an off-grid RV, electric propulsion system on a boat, or managing a solar-powered cabin, this battery capacity monitor supports up to 600A & 120V to handle heavy-duty loads, and gives you full control over your battery's health and performance. Prevent overloads, extend battery life, and keep lithium, AGM, and solar storage batteries running safely in any adventure.
Always Accurate with Auto Calibration – Unlike typical battery monitoring systems lose precision or need manual recalibration, this BT630 battery management system features a lab-grade shunt and self-calibrating design that locks in ±0.4% accuracy. It eliminates 1–2% drift and delivers long-term, precise readings.
Real-Time Alerts for Safer Power Management – After setting custom alert thresholds for voltage, current, SOC, power, and temperature, you’ll receive instant notifications through the app whenever values exceed safe limits, helping you prevent costly battery damage before it happens. A built-in temperature sensor and heat-resistant housing ensure stable operation in demanding RV, solar, or marine environments.
Easy Setup with RS-485 Expansion – The smart shunt is easy to install, with clearly labeled terminals to prevent wiring errors and shielded 4P/3P cables that reduce inverter and high-current interference. Step-by-step instructions, videos, and wiring photos are accessible via QR codes in the box and on the product page—ideal for tight or remote setups. For advanced users, the built-in RS-485 interface enables long-range data transmission and smooth integration into existing battery monitoring systems.
Long-Term Monitoring Without Drain – Tired of battery monitoring systems draining your battery while away? This BT630 battery management system uses just 0.4W—monitor 12V 200Ah batteries nonstop for 200 days (no accelerated discharge). Perfect for seasonal RVs, solar systems, or boats and cabins left unattended for extended periods, providing peace of mind while you're off-grid or in storage. Note: Monitoring duration is based on lab conditions and may vary in actual use.
30 Days Trends to Spot Issues Early – Beyond real-time monitoring, the marine RV battery monitoring system stores up to 30 days of voltage, current, and temperature data—shown as clear trend charts in your dashboard. By reviewing these history trends, you can quickly spot abnormal usage patterns, catch hidden battery issues before they escalate, and adjust your energy plan for safer, more efficient performance.
