Battery Testers

Features: 1. Application: This voltage indicator is used to test 1-8S lithium batteries. It can automatically check the voltage of each battery and the maximum voltage of the lithium battery, and features reverse polarity protection. 2. Overcharge Protection: Allows you to know the battery's operating status anytime, anywhere, preventing damage from over-discharge or overcharging. 3. Real-Time Display: By inserting the voltage indicator into the battery charging and balancing interface, you can view the battery's charge status in flight or standby mode. 4. Display Modes: This battery monitor displays the battery voltage, total voltage, minimum voltage, and remaining charge. 5. Safety Alarm: When the voltage falls below the preset value, an alarm sounds and an LED indicator flashes. The factory default value is 3.3V. You can readjust the voltage value and save the settings.
