1-8s Lipo Battery Tester Monitor Buzzer Low Voltage Alarm Voltage Checker with LED Indicator for Lipo Life LiMn Li-ion Battery (6PCS)

General description This voltage display is designed for 1S to 8S lithium battery detection, automatically measuring the voltage and total voltage of each cell. It features reverse connection protection and allows users to monitor the battery's working status to prevent damage from over-discharge or over-charge. The device can be plugged into the battery balance charging connector to check the battery charging status during flight or standby mode. Technical specifications Voltage detection accuracy: ±0.01V Group voltage display range: 0.5V~4.5V Total voltage display range: 0.5V~36V 1S test mode voltage range: 3.7V~30V 2S-8S low voltage buzzer alarm mode Alarm voltage setting range: OFF~2.7~3.8V Dimensions: 40 mm x 25 mm x 11 mm Installation Turn the display so that the digital display side is facing up. Plug the battery balance charging connector into the leftmost pin of the display. If there is no response, try plugging the balance charging connector in backward.
