2026 Bluetooth Battery Monitor with 600A Smart Shunt BT630, Track Volt/Amp/Watt/Capacity, 8 Protection Alarms, for LiFePO4/Lithium/RV/Solar/Marine/Off-Grid, Extend Battery Life, Easy Install
- & The BT630 combines a voltmeter, ammeter, battery fuel gauge, 600A smart shunt, and voltage alarm into one compact unit components that would cost you significantly more if purchased separately. You get a complete battery management system in a single, cost-effective installation. No extra gadgets, no recurring upgrades. Professional-grade monitoring that makes sense.
- " " Stop guessing your battery's state of charge. With Bluetooth connectivity and the PRO BMS App, your smartphone turns into a remote dashboard that shows voltage, current, power, true SOC (state of charge), and time remaining in real time. Whether you're in an RV, on a boat, or off-grid in a solar cabin, you always know exactly what your battery is doing at a glance.

- + Equipped with a 600A smart shunt and ± 0.4 % accuracy, this unit self-calibrates to stay precise year after year.
But we go further: the app stores up to 30 days of historical data on voltage, current, and temperature. See which device drains the most power, detect abnormal usage patterns, and optimize your energy habits before a small issue becomes a costly failure.
/ Set custom alerts for voltage, current, SOC, and temperature whenever readings go outside your preset safe zones, the app pushes instant notifications. An onboard temperature sensor works alongside a protective safety cover that guards against shocks and shorts a key safety advantage over exposed designs. Built to handle enginebay heat and freezing outdoor conditions, it's tough enough for the real world.
& Wide compatibility with LiFePO, Lithium, AGM, Gel, and Flooded LeadAcid batteries. The 600A capacity easily handles large inverters and heavy loads, while the 10V120V wide voltage range covers most RV, marine, solar, backup, and offgrid systems. Plus, a builtin RS485 port enables advanced integration with solar controllers or energy management systems. One monitor, endless applications.
