Keep an eye on your LiPo battery while you fly. This compact tester displays battery voltage on a clear digital screen and sounds a buzzer when the voltage drops too low, helping you avoid over-discharging your pack.
Suitable for 1S to 8S LiPo batteries, it measures just 40 × 25 × 11 mm and weighs approximately 10 g, making it easy to carry in your flight box. The stated measurement tolerance is ±5%.
