KG-F Bluetooth Battery Monitor 0-120V

Bluetooth Battery Monitoring For DC Power Systems

The JUNCTEK KG-F Bluetooth Battery Monitor is designed to give a clear view of battery voltage, current, power, capacity, amp-hours, watt-hours and operating time across compatible DC battery systems. It is a practical monitoring upgrade for caravans, RVs, 4WD touring setups, battery boxes, workshops, off-grid systems and other DC electrical applications.

0-120V Battery Voltage Range

The KG-F series supports DC voltage measurement up to 0-120V when externally powered, with a 10-120V range when self-powered. This makes it suitable for a wide range of battery systems, including lithium, LiFePO4 and lead-acid batteries, provided the battery is within the supported voltage measurement range.

Clear 2.4-Inch Colour LCD Display

The display module uses a 2.4-inch high-definition colour LCD screen to show key readings clearly. It displays real-time battery and electrical data in an easy-to-read format, helping you monitor charging, discharging and system performance without relying on guesswork.

Bluetooth App Control And Data Viewing

The monitor supports Bluetooth connection through a mobile app, allowing you to view battery data, curves and settings from your phone within the supported communication range. The app can display real-time and historical voltage and current curves, and also supports exporting historical data for easier system tracking.

Current Options For Different Installations

The KG-F series includes different current measurement options depending on the selected model. The KG110F supports 0-100A, while the KG140F supports 0-400A. This allows the monitor to be matched to the scale of the battery system, whether used for smaller DC setups or higher-current battery installations.

Tracks Capacity, Power And Energy Use

The unit can monitor battery capacity from 0% to 100%, with amp-hour measurement up to 9999.99Ah and watt-hour measurement up to 9999.99kWh. It also supports power measurement up to 72kW, making it useful for checking battery usage, charging performance and total energy consumption across compatible DC systems.

Charge And Discharge Direction Detection

The monitor can automatically identify current direction during charging and discharging. This helps show whether power is flowing into or out of the battery, making it easier to understand system behaviour in vehicle, caravan, auxiliary battery and off-grid power setups.

Adjustable Protection Functions

The KG-F series supports multiple adjustable protection functions, including over-voltage, under-voltage, over-current, over-power, over-temperature and time-limit protection. When used with a suitable relay, these protection settings can help disconnect output when values move outside the selected limits.

Configurable Recovery And Delay Settings

The protection recovery time can be set from 0 to 99 seconds, with delay time also adjustable from 0 to 99 seconds. This gives installers more control over how the system responds to protection triggers, making it suitable for different battery and accessory setups.

Pure Copper Shunt Hardware

The shunt and screws are made from pure copper material to support good electrical conductivity, lower heat generation and low power consumption. The shunt-based design allows the monitor to measure high-current battery systems while keeping the display positioned where it is easy to view.

Suitable For Multiple Battery Types

The monitor is suitable for a variety of battery types within the supported voltage range, including ternary lithium, lithium phosphate and lead-acid batteries. The actual battery capacity value can be set, helping the display provide more relevant capacity information for the specific battery system being monitored.

Useful For 4WD, Caravan And Workshop Electrical Setups

This Bluetooth battery coulomb meter is well suited to battery monitoring panels, dual battery systems, caravan power systems, RV electrical installs, touring vehicles, workshop DC benches and other applications where voltage, current, capacity and energy use need to be checked regularly.

Included Installation Components

The kit includes the display module, measuring module, sampler, sampler mounting plate, temperature sensor, terminal, communication cable, connection cables, screws and spacers. Correct wiring, relay selection where required and model selection should be confirmed before installation to suit the intended battery system.
