BX100 1-8S Lipo Battery Voltage Tester

BX100 1-8S Lipo Battery Voltage Tester is an essential safety and monitoring device for anyone operating Li-Po, Li-Fe, or Li-Ion battery packs. This compact and lightweight unit provides immediate, accurate readings of your battery’s overall voltage and the individual cell voltages, offering crucial insight into the pack’s health. By quickly identifying any unbalanced or failing cells, the BX100 helps prevent over-discharging, which can permanently damage expensive batteries. A key safety feature is the integrated low-voltage alarm, which pilots and drivers can configure to sound a loud buzzer when any cell drops below a user-set threshold. Simply plug the balance connector into the tester to ensure your power source is ready for optimal performance and a long life.

Key Features:

• Versatile Compatibility: Accurately measures Li-Po (Lithium Polymer), Li-Fe (Lithium Iron), and Li-Ion (Lithium Ion) batteries from 1 cell (1S) up to 8 cells (8S).
• Cell-by-Cell Monitoring: Displays the voltage for each individual cell in the pack, allowing you to check for balance and diagnose problems quickly.
• Integrated Low-Voltage Alarm: Features a loud, audible buzzer that alerts the user when any single cell falls below a configurable safe voltage level.
• Overall Voltage Display: Shows the total voltage of the battery pack, in addition to the individual cell readings.
• Clear LCD Screen: A bright digital display ensures you can easily read the voltage values even in bright outdoor conditions.
• Reverse Polarity Protection: Built-in circuitry protects the tester from damage if you accidentally connect the balance lead incorrectly.
