3PCS Lipo Battery Checker Module RC Lipo Battery Voltage Detector with Adjustable Low Voltage Buzzer Alarm and LED Indicator for 1S-8S Iithium Battery

Product Features: 1-8S New 2 in 1 Battery Monitor BB Low Voltage (Adjustable) Alarm/Dual Function. One product has two functions, battery display and low voltage alarm (low voltage alarm can be adjusted). Warm Tips: Set the alarm on the black button between the two speakers. Product Introduction: This voltage display is used for 1S~8S lithium battery detection, automatically detects the voltage and total voltage of each cell of the lithium battery. Supports reverse connection protection. It allows you to understand the working status of your battery anytime and anywhere, so that your battery will not be damaged by over-discharge or over-charge. When the voltage is lower than the set value, the buzzer will sound and the red LED light will flash; the factory default setting value is 3.3V, press the button to change the voltage setting value, and automatically save the user's current setting value. Product parameters: 1. For 1S-8S lithium battery detection 2. Voltage detection accuracy: ± 0.01V 3. Group voltage display range: 0.5V~4.5V 4. Total voltage display range: 0.5V~36V 5. 1S test mode voltage range: 3.7V~30V 6. Low voltage buzzer alarm mode: 2S - 8S 7. Alarm voltage setting range: OFF~2.7~3.8V 8. Dimensions: 40mm x 25mm x 11mm 9. Weight: 9g/pcs Package contains: 3PCS Lipo Battery Voltage Detector Low Voltage Buzzer Alarm Module
