Feature:1. ENERGY SAVING: The shunt and screws of the battery monitor are made of copper material, which has good conductivity, low heat and low power consumption. Will not consume too much battery power in standby state2. PREVENT DAMAGE: You can set over voltage, under voltage, over current, over power, and external over temperature protection. When the value is out of the protection value range, the output state of the coulometer is turned off (need to be used with a relay) to prevent damage to electrical equipment3. SETTABLE TIME: The protection recovery time and delay time of coulometer can be set, suitable for various occasion4. SHORTCUT KEY DESIGN: Battery meter adopt shortcut key design, not only greatly simplifies the operation steps, but also feels comfortable5.
