Feature: 1. [Remote Monitoring] The battery monitor supports real time remote monitoring via WiFi, Bluetooth, and APP connectivity. Keep track of your battery status anytime, anywhere by staying connected to the battery monitor from your smartphone or other devices. 2. [Enhanced User Interface] Featuring 2.4 inch HD color LCD screen with optimized interface, offering larger, clearer text. With dark and light mode options, ensuring easy visibility of information. The silicone key provides smoothly operations, fast response, and comfortable touch. 3. [Multiple Parameter Measurements] This battery monitor can measure voltage, current, power, charge discharge capacity, watt hour, time, and other physical parameters. Set parameters to enable functions such as overvoltage, undervoltage, overcurrent, overpower, overtemperature, and time limited protections. 4. [Built in Reminder] With a built in reminder, you can set low capacity or low voltage reminders. Once the values fall below the preset levels, the buzzer will sound immediately, accompanied by a pop up reminder, allowing you to stay informed of the device status. 5. [Wide Battery Compatibility] Compatible with various types of batteries including VRLA, LFP, Li Ion, NI MH, and other battery types within the voltage range of 10 to 100V.

Package List: 1 x WiFi Battery Monitor 1 x Shunt 1 x 1m Red Positive Wire 1 x 5m Communication Wire 1 x User Manual Note: Before first use, the battery effective capacity and current remaining battery percentage must be correctly set. If the effective capacity of the battery or the current remaining battery percentage is unknown, follow the steps below to check: 1. Charge the battery pack completely. 2. Input preset battery capacity setting in the system settings, for example, if the rated battery capacity is 150AH, we set 150AH as the preset battery capacity. (You can check the rated capacity on the battery nameplate). 3. Set the remaining capacity percentage to 100%, then discharge the battery pack. 4. After discharge, the remaining capacity value displayed on the display is 10AH. The actual battery capacity is 140AH (150 minus 10), which means the battery has discharged a total of 140AH and cannot be completely discharged. Therefore, we set the actual discharged capacity of 140AH as the preset capacity and set the capacity percentage to 0%. This completes the battery setup.
