Digital LCD display provides clear digital readings with high accuracy. Power meter displays amps, volts, and watts continuously in real time after connection. High accuracy: 0-150 amp measurement, 0.01 amp resolution. Measures 0-60 volts, resolution 0.01 volts. 0 - 6554W, 0.1W resolution. 0 - 65 Ah, resolution 0.001 Ah. 0 - 6554 Wh, resolution 0.1 Wh. Provides 8 electrical measurements: current (A), voltage (V), watt (W), amp-hours (Ah), watt-hours (Wh), peak amps (Ap), minimum voltage (Vm), peak watt (Wp). Multifunctional tool: check that the working voltage is sufficient under load. Prevent surge current from damaging batteries, controller, motors, wiring and connectors. Check that the battery charger is working correctly (connect battery and charger). unction: the individual cells are balanced. Set the cut-off voltage and check the battery capacity. Identify the receiver and the actual operating current to determine if the UBEC, etc. happened. Feature: 1. Digital LCD display provides clear digital readings with high accuracy. 2. Has a wide working voltage from 4.8V to 60V, which can measure more accurately. 3. High plastic and copper wire material quality, corrosion resistance and long life. 4. Small, light, easy to install, can bring you more convenience for testing. 5. Can measure both current and voltage capacity to better meet your measurement needs.
