Low Voltage Battery Tester with Buzzer Alarm

This electronic device battery tester is designed for DIY electrical projects and is compatible with 1-8S Lipo, Li-ion, LiMn, and Li-Fe batteries. It offers precise voltage detection with an accuracy of 0.01V, ensuring reliable results every time you test your batteries. The unit voltage display ranges from 0.5V to 4.5V, while the total voltage display accommodates a range of 0.5V to 36V.

For specialized testing, the 1S test mode operates within a voltage range of 4-15V, making it versatile for various battery configurations. Additionally, the low voltage alarm mode is suitable for 2-8S batteries, with alarm set values adjustable from OFF to 2.7V to 3.8V. This feature allows you to monitor your batterys health and prevent over-discharge, prolonging battery life and performance. The incorporation of a buzzer alarm adds an extra layer of safety, alerting you when voltage levels fall below your set threshold.
