DC 5V Typec LCD Battery Capacity Tester MAh MWh for 18650 Lithium Battery Digital Measurement Battery Power Bank Detector Module

Features: 1: Widely used 2: Added charging function 3: Exquisite and compact appearance 4: LCD display 5: Preset three working modes 18650 battery capacity tester LCD display (with charging function) type-C port Test voltage: ≤ 5V Display mode: 128 × 64px LCD Capacity range: 9999mah Energy range: 9999mwh Timing range: 999:59:59 Working battery: flat head 18650 battery Power interface: type-C External working power supply: 5V 1a (the power supply is self-contained, and the mobile phone charger can be used). The charging mode (charge) and automatic mode (auto-test) can be used normally only when the external working power supply is connected. Product size: 115 × eighty-one × 31mm (product); one hundred and fifty × one hundred × 40mm (package), Product weight: 110g (including packaging); Net weight 74g Safety tips: when discharging, the load resistance will release a high temperature of 60 ~ 80 ℃. During use, keep ventilation to avoid approaching flammable and explosive substances. Notice to pay attention to safety and avoid scalding. Working mode (5V power supply is required) Auto-test automatic mode (boot default mode) Start → charge (when the charging current is less than 0.12A, trigger full charge and stop charging) → discharge (when the load voltage is less than 2.7V, trigger discharge is completed) → charge (when the charging current is less than 0.12A, trigger full charge and stop charging) → complete stop ① When charging, the capacity and energy values are not recorded, only timing. ② When discharging, record the capacity and energy value, which is the same as timing. Charge (charge mode) Start → charge (when the charging current is less than 0.12A, trigger full charge and stop charging) → complete the stop ① Only the charging time is recorded, and the charging capacity and energy are not recorded Discharge mode Start → discharge (if the load voltage is less than 2.7V, trigger discharge completion → complete stop) ① Record discharge capacity, energy and time. Note: ① In the discharge process, as long as the battery load voltage is detected to drop to 2.7V, the discharge will stop. After the discharge is stopped, the battery will be unloaded and the voltage will rise; A single discharge process can only detect the capacity released by the battery at the stage when the voltage drops to 2.7V for the first time after the discharge starts, which can be simply understood as a single available capacity rather than a calibrated battery capacity. ② Shutdown and restart; Switching mode; Long press the start key to clear all data, and shut down without saving historical data. ③ Test ① install 18650 battery for test. Test ② test through type-C external charging treasure or power supply ≤ 5V. However, test ① and test ② cannot be used for test at the same time to avoid accidents caused by overshoot of 18650 battery without protection. ④ To operate the charging mode, an external working power supply must be connected Package Include: 1 * battery capacity tester
