Dual LiPo Voltage Checker & Alarm

This two-pack provides an all-in-one voltage checker and low-voltage alarm for 1S to 8S lithium batteries. Each unit reads individual cell voltages and total pack voltage with a precision of +/-0.01V. The built-in buzzer and red LED alert you when cell voltage drops below a user-defined threshold. It supports LiPo, LiFe, LiMn and Li-ion chemistries with JST-XH balance leads.

Verify JST-XH Balance Lead Compatibility

Ensure your batteries use the standard JST-XH balance connector with approximately 0.12 inch pin spacing before ordering. The checker draws power directly from the balance plug, so no separate battery is required for operation. Reverse-connection protection prevents damage if the plug is inserted incorrectly. Units are certified to UL 61010-1 and IEC 61010-2-030 safety standards.

Adjustable Alarm Threshold with Cycle Display

The low-voltage alarm triggers an audible buzz and flashing red LED when any cell falls below the set value. The threshold adjusts between 2.7V and 3.8V per cell in 0.1V increments, defaulting to 3.3V. A single button cycles the LED display through cell voltages, total voltage, lowest cell voltage and remaining capacity percentage. Settings are saved automatically after adjustment.

Questions about this item

What comes in the box and what must I supply myself?

The pack contains two voltage checker and alarm units. Each unit is ready to use with any 1S-8S LiPo, LiFe, LiMn or Li-ion battery that has a JST-XH balance lead. No separate power source is needed because the checker draws power from the balance plug itself.

How do I decide which alarm threshold to set between 2.7 V and 3.8 V?

The alarm triggers when any cell drops below the chosen value. The factory default is 3.3 V per cell. Press the button on the unit to step through the range in 0.1 V increments from 2.7 V up to 3.8 V, or select OFF to disable the alarm. The setting is saved automatically.

What does the ±0.01 V detection precision mean when I am monitoring a pack in the field?

Each cell voltage and the total pack voltage are displayed with a resolution of 0.01 V, so you can see small differences between cells and catch a drifting cell early. The buzzer and red LED activate the moment any cell falls below your chosen threshold, giving an audible warning even when the display is not visible.
