Product Details
RELiON InSight Series 12V Fuel Gauge (BI-3140R-12)
RELiON InSight Series 12V Fuel Gauge (Model: BI-3140R-12) – High-Performance Battery Monitoring Solution for RELiON InSight Lithium Batteries
The RELiON InSight Series 12V Fuel Gauge (Part No: BI-3140R-12) is a low-draw, constantly backlit monitoring device that provides real-time state of charge (SOC) for up to 14 InSight batteries connected in parallel. Pulling data from battery CANs, it displays SOC as a percentage from 0-100%, the number of batteries detected, and alerts via “LOBATT” messages (steady below 20% SOC, flashing below 10% SOC) to ensure timely charging. With a minimal operating current of 29 milliamps, it's designed for seamless integration with RELiON InSight series lithium batteries, offering accurate monitoring for RV, marine, solar, and commercial setups without draining power.
Key Features:
- Real-Time SOC Monitoring: Receives current data from parallel-connected battery CANs; calculates and displays remaining amp hours as 0-100% SOC.
- Battery Detection: Shows the number of batteries detected in the parallel configuration for easy system status checks.
- Low Battery Alerts: Displays “LOBATT” message when below 20% SOC (steady) or 10% SOC (flashing) to prevent deep discharge.
- Low Current Draw: Only 29 milliamps operating current, minimizing impact on battery life.
- Backlit Display: Constantly illuminated for visibility in low-light conditions, ideal for marine or RV use.
- Versatile Compatibility: Works with up to 14 InSight batteries in parallel; compatible with 12V systems.
- Rugged Durability: IP67-rated for dust and water resistance; operates from 14°F to 185°F (-10°C to 85°C).
- Eco-Friendly: Complements RELiON’s sustainable LiFePO4 batteries with no additional maintenance required.
