Here are some key features and functions of the Cellmeter 8:

Battery Testing: The Cellmeter 8 can test and monitor various types of batteries, including lithium-polymer (LiPo), lithium-ion (Li-ion), nickel-metal hydride (NiMH), and nickel-cadmium (NiCd) batteries. It provides information on the individual cell voltage, total voltage, and the difference in voltage between cells in a battery pack. This data helps users assess the health and balance of their batteries.

Servo Testing: This device can also be used to test and calibrate RC servos. Users can connect a servo to the Cellmeter 8 to check its performance, position accuracy, and response to input signals.

Balancing Function: The Cellmeter 8 includes a balancing function for LiPo batteries. This feature ensures that each cell in a LiPo battery pack is at the same voltage level, promoting safer and more efficient use of the battery.

Digital Display: It features a digital LCD display that shows important information such as voltage, cell voltage, and servo position.

Portability: The Cellmeter 8 is typically compact and portable, making it convenient for use in the field or at the RC flying or racing field.

Multiple Functions: Beyond battery and servo testing, some models of the Cellmeter 8 may offer additional functions like measuring battery internal resistance, serving as a receiver tester, and more.
