About This

• EMBRACE THE 400A SWEET SPOT: Why pay for capacity you'll never use? Unlike bloated specs, our 400A rating is precision-engineered for real-world RV, marine, and solar applications (typically 100-300A peaks). This ideal match eliminates the inaccurate readings, excess heat and wasted cost of oversized shunts. You get reliable, stable data and a cooler-running unit, no compromises, just smarter performance
• ±1% ACCURACY TO PROTECT YOUR BATTERY INVESTMENT: Crafted with low-resistance materials and multi-point factory calibration for true ±1% accuracy, even under high loads. Know your exact power left to prevent costly battery damage from over-discharge and use your energy with total confidence
• PROFESSIONAL RESULTS IN MINUTES: Professional installation, simplified. Our "Wrong-Proof" Ports and built-in Bluetooth remove the two biggest hassles: miswiring and complex display setup. No more guesswork. Be guided by our video tutorials for a pro finish in minutes. (Guides via QR code in box)
• CONFIDENT PROTECTION: Designed with built-in reverse polarity and overload protection that anticipates real-world errors before they become expensive failures. It gives you the freedom to install with confidence, knowing even if things don’t go perfectly, your system has your back. We believe reliable energy should also be safe energy—so you can enjoy the road, the water, or off-grid living without worrying about hidden risks
• CONVENIENT BLUETOOTH CONTROL: Move beyond cramped wired displays. Our built-in Bluetooth (with a practical range of approximately 10 meters in open areas) and intuitive app put clear, real-time data—like voltage, current, and SOC—right on your phone. Please note that walls and obstacles will reduce the effective range
• MINIMAL POWER IMPACT FOR MAXIMUM PEACE OF MIND: With an ultra-low 0.5W power draw, BM1000 can typically operate for extended periods without significantly affecting your battery's reserve. This efficient design helps preserve your power for what truly matters, making it a reliable companion for seasonal use or long-term storage
• THE POWER OF HINDSIGHT FOR YOUR BATTERY: Scroll back through 30 days of energy data like a timeline. This "time-travel" insight helps you spot wasteful patterns, optimize your usage, and extend your battery's life—turning past data into future savings
