Deep discharge is the number one cause of premature death for Li-Po batteries. With this 2-in-1 voltage sensor, you have total control over the remaining energy in your model, whether you're on land, in the air, or on the water.
An Essential Dual Function
Digital Voltage Tester: Simply plug your battery’s balance connector into the module. The LED screen will display the total pack voltage, then scroll through the individual voltage of each cell with surgical precision. Perfect for checking if your batteries are charged before takeoff!
Low Voltage Alarm (Buzzer): Install the module in your plane, drone, or car. Thanks to its ultra-powerful dual buzzer, it emits a piercing sound as soon as any cell drops below the critical threshold you have set. Impossible to miss, even with a gas engine nearby!
Fully Adjustable
A simple press on the button located between the two buzzers lets you set the alarm trigger threshold (from 2.7V to 3.8V, or OFF mode). The module remembers your setting for future use.
Key Features:
Universal: Compatible with all 1 to 6 cell Li-Po / Li-Ion / LiMn / Li-Fe batteries.
Precision: Clear and accurate digital display to within 0.01V.
Sound Power: Buzzer audible from a great distance for maximum safety in flight.
Lightweight & Compact: Fits easily anywhere without weighing down your model.
Expert Opinion
"This is the accessory we always recommend to all our customers, beginners and experts alike. We use it every day in the workshop to check our packs. Its real plus? The buzzer is really strong: even if you fly a bit far, you'll hear it whistle to tell you it's time to land. A tiny investment to save batteries that cost a lot!"
