Li-Po 1-8S Voltage Tester with Buzzer Alarm

From the shop's description

Li-Po 1-8S Voltage Tester with Buzzer Alarm Li-Po 1–8S Voltage Tester with Buzzer Alarm is a handheld battery analyzer designed for series pack monitoring. Simply connect the tester’s balance-plug lead to your 1–8S LiPo/Li-Ion/LiMn/LiFe pack; it will cycle through each cell, displaying cell voltages (0.5–4.5 V) and then the total pack voltage (0.5–36 V) on its LCD screen with ±0.01 V accuracy. The built-in buzzer alarm and LED flash when any cell falls below your preset threshold (adjustable 2.7–3.8 V), helping prevent over discharge and extending battery life. Powered directly by the battery under test, it requires no external or internal power source. Its rugged ABS or aluminum housing makes it durable and portable for field use in RC, drones, and other battery-powered electronics applications. Features: Use for 1-8S Lipo/Li-ion/LiMn/Li-Fe The 1-8S Lipo Battery Voltage Tester is a versatile and easy-to-use tool for measuring and monitoring the voltage of LiPo batteries. It can accommodate a wide range of battery configurations, from 1S to 8S, and provides clear and accurate voltage readings for each cell. Compact, easy to carry.
