Benefits

Battery Protection: Automatically detects the voltage of each lithium battery cell and the total voltage. When the voltage falls below the set value, a buzzer sounds and a red LED flashes, reminding the user to take immediate action to prevent over-discharge and thus extend battery life.

Improved Safety: In applications such as model aircraft, the device monitors battery voltage in real time. When the voltage is too low, a sharp alarm sounds, prompting the user to land or stop the device immediately, preventing damage or accidents caused by battery depletion, such as the risk of a model aircraft crashing.

Accurate Warning: The alarm is highly sensitive, eliminating false alarms and missed alarms. Using a specific frequency, the alarm sound is loud and clear, even in noisy outdoor environments, providing a truly accurate warning and allowing users to monitor battery status in real time.

Easy to Use: Compact and easy to install, it typically requires only connecting to the battery's balance cable and then to a remote controller or receiver. It takes up virtually no space and requires no complex setup. Multifunctional: Not only does it display battery voltage and charge in real time, it also issues an alarm when the voltage is too low. Some models also display information such as remaining flight time, allowing users to clearly understand battery status. This versatile device meets a variety of user needs.

Applications

Model aircraft: This is a common accessory for model aircraft enthusiasts and can be used with various models, including cross-country drones and fixed-wing aircraft, helping players monitor battery status in real time and ensure flight safety.

Unmanned equipment: In addition to model aircraft, it is also suitable for other types of unmanned equipment, such as drones for aerial photography and autonomous vehicles, to prevent loss of control or damage due to low batteries.

Electric vehicles: It can be used in electric bicycles and electric motorcycles, reminding users to charge their batteries promptly, avoiding the inconvenience or danger of low batteries during driving.

DIY battery projects: In some homemade battery projects, such as DIY power banks and solar energy storage systems, it monitors battery voltage, protects battery safety, and ensures stable system operation.

Other Electronic Devices: For specialized electronic devices using 1-8S lithium batteries, such as portable instruments and small power tools, you can also install a 1-8S battery indicator or BB low-voltage alarm to monitor battery status and prevent over-discharge.
