You can choose the real-time dynamic tracking interface, where the high-definition display screen draws the battery power change curve in real time, accurately capturing fluctuations during the charging/discharging process, making the energy flow clear at a glance. You can also choose the real-time monitoring interface for battery information, with a simple and elegant UI design that displays real-time changes in battery parameters more clearly. Accurately grasp battery voltage/current/capacity parameters, use batteries healthily, and improve battery life. Support custom low capacity alarm values. Support zero capacity/full capacity voltage settings Support brightness adjustment function (automatic/manual) Support shutdown voltage setting Specification: Voltage applicable range:6-60V Display screen:TC169SE:280x240 pixels high color gamut Maximum current resolution: 1mA (0.001A) Display content: current, voltage, SOC (percentage), capacity, power, remaining time, sampling temperature, charge and discharge status.
