Prevent Battery Damage with Instant Voltage Tracking

Lithium polymer (Lipo) batteries are powerful but notoriously sensitive. Dropping below a safe voltage threshold can cause irreversible damage, swelling, or even fire hazards. This 1-8S Lipo Battery Voltage Tester is your first line of defense. By plugging your battery's balance lead directly into the pins, the bright LED display instantly cycles through individual cell voltages and the total pack voltage.

The Ultimate Guard Against Over-Discharge

You don't just need to know your battery's status; you need to be warned before it's too late. This device features a highly audible Low Voltage Buzzer Alarm designed to cut through ambient noise. Whether your drone is hovering in the distance or your custom STEM project is running continuously on the workbench, the dual buzzers and flashing red LED will ensure you never miss a critical voltage drop.

Customizable Alarms for Every Project

Different applications require different safety margins. The onboard push button allows you to easily customize the alarm threshold between 2.7V and 3.8V per cell, or turn it completely off. The device automatically saves your preference for the next use. It is fully compatible with Lipo, Li-ion, LiMn, and Li-Fe battery chemistries, making it a versatile staple for DIY hobbyists, professional electronics technicians, and institutional labs.
