Product Description KG-F Series Wireless Bluetooth Battery Coulomb Counter Description The KG-F Series color screen wireless Bluetooth battery coulomb counter is a professional device for accurately monitoring battery capacity. This advanced instrument also keeps track of battery voltage, current, power, ambient temperature, electrical energy, and the time required for full charge. Additionally, it measures energy consumption during charging and discharging. It supports a current range of 0-100A, 0-400A, or 0-600A, and is compatible with batteries up to 120V when fully charged. Features 2.4-inch high-definition color screen with enhanced clarity and aesthetics. Mobile app connectivity through wireless Bluetooth to view data and configure settings. Real-time and historical voltage and current curves are accessible via the mobile app, with exportable historical data. Connected with a 3m 4P telephone line, extendable up to 30 meters for easier installation. Constructed with pure copper shunts and screws to reduce standby power consumption. Configurable relay settings for over-voltage, under-voltage, over-current, over-temperature, and over-power protection. Wireless firmware updates available through the mobile app. User-calibrated parameters for voltage, current, and temperature.
