Product overview
The ANAXIN ANX-16-ZB-A is a 12S–18S smart battery (21700) with integrated charge indication, audible warnings and battery management functions. Four LEDs display the current charge level. Each power-on starts a self-test: if the cell voltage difference exceeds 100 mV, all four red LEDs flash together 10 times and the buzzer sounds to signal an imbalance requiring balancing maintenance. Users can manually activate smart maintenance for severe imbalance. When powered on but unused, the battery automatically shuts down after 3 minutes.
CAN and serial communication, including wireless Bluetooth, provide battery information for monitoring and connection to a flight controller. Both communication methods deliver individual cell voltage, total voltage, current, state of charge, temperature, cycle count and abnormal-event count; a mobile app also displays battery information over Bluetooth. The battery management system continuously records operating information, including balancing history, with date-and-time queries and Excel export through PC software. Combined LED and buzzer alarms indicate conditions including overvoltage, undervoltage, charging overcurrent and excessive temperature.
