The AIMS Power BATMON500 Bluetooth Battery Monitor is a high-precision battery fuel gauge for lithium and most common battery types up to 80V. It lets users check battery status through the included monitor display or through a smartphone using the Bluetooth app. Using the included current shunt, the monitor measures discharge and recharge current, then calculates ampere-hours going in and out of the battery. It displays key battery data including battery voltage, battery current, state of charge, and total ampere-hour capacity. Designed for lithium-ion, lead-acid, and nickel-metal hydride batteries, this 500A battery monitor is backed by a 5-year warranty.
This AIMS Power battery monitor is compatible with lithium-ion, lead-acid, and nickel-metal hydride batteries. It gives users a clear way to track battery status from the display or smartphone app, making it useful for RV, marine, off-grid, vehicle, and backup power systems.
The included current shunt measures discharge and recharge current to help calculate ampere-hours in and out of the battery. This gives users practical visibility into battery usage, charging activity, and remaining capacity.
The monitor displays battery voltage, battery current, state of charge, and total ampere-hour capacity. High-precision voltage readings are taken through a field-installed sense wire for real-time battery monitoring.
The kit includes the current shunt, shielded wire, display, butterfly nut, 22AWG sense wire, and square bezel. This gives users the core components needed for a clean battery monitoring setup.
This AIMS Power 500A Bluetooth battery monitor helps users track voltage, current, state of charge, and amp-hour capacity from the display or smartphone app.
With support for lithium-ion, lead-acid, and nickel-metal hydride batteries, the BATMON500 is a practical battery fuel gauge for RV, marine, off-grid, and DC power systems.
