Feature:1. DELICATE DESIGN: The battery tester is designed with an acrylic shell baffle, making the tester durable and beautiful.2. TESTING DETAILS: The battery tester supports 1 to 24S lithium battery pack (battery voltage is between 2V and 4.5V), and the measurement accuracy of each string of battery voltage is about 0.003.3. DATA DISPLAY: This battery tester displays each string voltage, total voltage, maximum string voltage, minimum string voltage, maximum voltage difference of battery pack, average voltage, balance voltage, battery string number.4. SOUND ALARM: This battery tester has reverse connection, high voltage warning and prompt (more than 4.5V), low voltage (less than 2V).5. CONVENIENT USING: The battery tester supports mixed plug (no need to start from B1), support Type c and DC power supply modes (DC5V), support Chinese and English switching, and use more convenient.Specification:Item Type: Battery TesterMaterial: Acrylic, PCBBattery String Support: 1 to 24 strings (2V-4.5V)LCD Large Screen Display: Voltage of each string, total voltage, maximum string voltage, minimum string voltage, maximum voltage difference of battery pack, average voltage, balance voltage, number of battery stringsLanguage: Chinese, English (switch)Charging Interface: Type C, DC interface (DC5V).Package List:1 x Battery Tester 1 x Type C Cable 1 x Extension Board 3 x Electronic Component
