AOICRIE Lipo Battery Checker 6Pack Voltmeter 1S-8S .01V precision 1655

Compact Six-Pack Voltage Checker

This AOICRIE set includes six identical battery checkers that read individual cell voltages and total pack voltage for any 1S-8S lithium chemistry. Each unit plugs directly onto the JST-XH balance lead with 0.12 inch pin spacing and automatically detects the pack without buttons or menus. The built-in reverse-connection protection prevents damage if the plug is inserted backwards. The package suits pilots and technicians who monitor several packs in parallel.

Precision Measurement and Adjustable Alarm

Voltage detection precision is +/-0.01V across the full 1S-8S range, giving reliable per-cell data for LiPo, LiFe, LiMn and Li-ion chemistries. The low-voltage alarm triggers between 2.5V and 3.8V per cell in 0.1V increments, with a factory default of 3.3V. A single button cycles the threshold and saves the new value automatically. When any cell falls below the set point a loud buzzer sounds and a red LED flashes, providing clear warning even in noisy environments.

Replaces Single-Unit Checkers for Fleet Operations

Builders who currently carry one tester and move it between packs gain continuous monitoring on up to six batteries at once. The jump is worth it when pre-flight checks, charge verification and in-flight alarms are needed simultaneously across multiple aircraft or ground vehicles. Users who only ever handle one or two packs at a time will not benefit from the extra units and can choose a single checker instead.
