Features Durable material: silicone key combinations feel comfortable, simplify the operation steps, the acrylic plate effectively protects the screen with good light transmission, the brass shunt and screws have good conductivity and low heat generation. Multiple functions: can set parameters, support BT when viewing measurement data, control instruments and firmware upgrades via the mobile app, automatically detect and monitor current and current direction. Multiple control: supports display control, provides a communication protocol, adopts 485 communication, supports secondary development and can switch communication addresses to control 99 units each; mobile app control, BT connection and display data and curves. Measuring parameters: this battery monitor can measure voltage, current, power, charging and discharging capacity, watt hours, time, etc., with overvoltage, undervoltage, over-current, over-voltage and over-temperature protection. Protection alarm: when the value exceeds the set limit, the protective function of the meter is activated, an alarm will sound and remind you that the relay (not included) disconnects the circuit to protect the meter from damage.
