Wide Cell Support (2S to 8S or More)
Can test batteries with different numbers of cells, from small 2-cell packs up to large 8-cell packs, making it versatile for various drone and RC battery sizes.

Individual Cell Voltage Accuracy
Measures the voltage of each cell separately with good precision, so you can easily spot any weak or damaged cells that might affect battery performance or safety.

Voltage Bar Graph or Digital Display
Shows battery status clearly using either LED bars or numeric LCD screens, allowing quick and easy reading of the battery condition.

Compact and Portable Design
Small and lightweight enough to carry around comfortably, so you can check batteries anywhere—from your workshop to the flying field.

Easy Plug-and-Play Connection
Connects directly to the battery’s balance lead without needing extra cables or setup, making it user-friendly for beginners and pros alike.

Low Power Draw During Testing
Uses minimal battery power during the check, so it doesn’t drain or harm the battery while measuring voltages.

Built-in Safety Features
Some models protect against common mistakes like reversed connections or shorts, preventing damage to both the tester and the battery.

Battery Condition Indicator
Gives clear alerts or visual signals if any cell’s voltage is out of the safe range, helping you maintain battery health and avoid dangerous situations.
