TBB-BM500 High-Precision Battery Monitor
Professional 500A Shunt & Display Kit with Bluetooth
The TBB-BM500 is a professional-grade battery monitoring system designed to give you total control over your power reserves. Whether you are managing an off-grid solar setup, a marine vessel, or a high-end campervan, this high-precision coulometer tracks every amp-hour entering and leaving your battery bank. By measuring current directly through the included 500A shunt, it provides real-time data on your State of Charge (SoC), remaining capacity, and time-to-go, ensuring you never run out of power unexpectedly.
RELIABILITY: Built to meet or exceed OEM specifications for long-lasting performance in demanding RV and marine environments.
