The 1-8S Lipo/Li-ion/LiFe Battery Voltage Tester with Low Voltage Buzzer is a compact 2-in-1 tool that measures individual/total cell voltages (0.5-36V total range) and triggers a loud audible alarm (adjustable 2.7-3.8V, default 3.3V) with red LED flashing when voltage drops too low. Designed for 1-8 cell packs, it plugs directly into the balance connector, preventing over-discharge during RC use. Voltage detection precision: 0.01V Unit voltage display range: 0.5~4.5V Total voltage display range: 0.7~30V 1S test mode voltage range: 4-15V Low voltage alarm mode for 2-8S Alarm set value range:OFF~2.7~3.8V Size: 40mm x 25mm x 11mm Original box: NO Net weight: 9g Package weight: 15g Color: Red
