It uses a closed-loop control principle to ensure that the discharge current reaches a set value and remains constant regardless of voltage changes. The tester uses a low-drift Manganin resistor for current sampling and a MOSFET as the current control device, keeping the controlled current error within 0.4%. An MPU controls the entire circuit, including the display interface, adjustment buttons, and timing. The timing on this tester is based on the product of current and time, which is used to calculate the battery capacity.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb style=\"background-color: rgb(255, 255, 0);\"\u003eSafety Warning:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003eThis tester is a bare-board device, and the battery connection terminal is connected to the heatsink. Operators must have electrical safety knowledge and must operate it under safe voltages! During the discharging state, the heatsink becomes extremely hot; operators should take appropriate protective measures to avoid burns.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb style=\"background-color: rgb(255, 255, 0);\"\u003eDisplay Interface:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e* Intuitive Display: The tester features a dual 4-digit LED display and five indicator lights for Measured Voltage (V), Battery Capacity (AH), Discharge Current (A), Cutoff Voltage (V), and Temperature (°C), providing clear and easy-to-read measurement data.\u003c\/div\u003e\u003cdiv\u003e* Measured Voltage (V): Displays the actual voltage of the battery or other power source connected under test.
