<p>The product automatically recognizes and detects the current in both charging and discharging directions. When charging, the color of the current is green; when discharging, the color of the current is blue.</p> <p>Suitable for a variety of batteries: ternary lithium batteries, lead-acid batteries, lithium phosphate batteries, etc., as long as the battery is within the voltage measuring range.</p> <p>The shunt and screws are made of pure copper material, which has good electrical conductivity, low heat generation, and low power consumption. In the standby state, it not consume too much battery power.</p> <p>After configuring the relay, it can realize over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, Low temperature protection and over-power protection (the delivery list does not include relays)</p> <p>The product has added a self-calibration function, and the current and capacity values can still remain accurate after long-time work.</p> <p>Amp-hour, watt-hour, and time data can be cleared during the measurement process without affecting measurement. The voltage and current values can also be fine-tuned to accurate capacity.</p> <p>The product can accurately measure parameters such as voltage, current, battery capacity, power, power consumption, ambient temperature, battery life, charging time, and battery cumulative capacity.</p> <p>Tips:The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use.</p> <p>Colour:As Shown</p> <p>Material:Plastic</p> <p>Package Contents:</p> <p>1 * Battery monitor with terminal connection cable</p> <p>1 * Temperature sensor</p> <p>1 * Sampler</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.</p>
