The Epoch Pro APP is specifically designed for Epoch Pro batteries and supports information monitoring of individual batteries, as well as battery systems in air connection or wired connection, etc. You can also easily realize the Bluetooth function of the GC2 batteris by connecting the Bluetooth module for more comfortable and convenient user experience. Make sure you have the latest app version. Turn on your Bluetooth. Tap the icon to open the App. It will search for all Epoch Pro batteries within the range of your Bluetooth device and provide a list. If all the batteries are not listed, move closer to the battery location and refresh the screen. Choose the battery you want to look at. The Epoch intelligent battery management system and the active equalizer are connected via Bluetooth to monitor the battery status, collect, store and process information during battery operation in real time, exchange information with external devices, and solve the safety, usability and usage of the lithium battery system. The key issue of life is to extend the service life of the battery to a certain extent, and to enhance the stability of the battery pack to a certain extent. 1. Display real-time SOC, voltage, current, capacity, temperature, and other parameter values, and display them in the form of instrument panels and numbers; 2. Display the real-time voltage and alarm status of all single batteries. If the reported parameters trigger the alarm value or protection value, an alarm will be prompted; 3. Cell temperature warning. Real-time alarm for over temperature, over current, over voltage, under voltage. 4. Record the warnings/protection that occur at each moment. Best Regards!
