² This is battery voltage checker and low voltage buzzer 2-in-1 unit.
² 1S test mode test range 3.7 to 30V, which means you can test the battery pack without balance connectors like RX battery pack etc., LiPb or other power source voltage.
² In other words, this very little devise can be used as a simple digital voltage meter.
² Loudly buzzer can be heard from distance; you can put this device on your plane and use it as on- board alarm, so you can hear the low voltage alarm during flight.
² Application: Use for 1-8S Lipo/LiMn/Li-Fe
² Voltage detection precision: ± 0.01V
² Unit voltage display range: 0.5-4.5V
² Total voltage display range: 0.5 - 36V
² 1S test mode voltage range: 3.7-30V
² Low voltage alarm mode for 2-8S
² Alarm set value range: OFF-2.7-3.8V
² Weight: 8.7g/ 0.31oz
² Size: 40 x 25 x 11mm
² The sound of the low voltage alarm is very big, so please be prep-ared when use it for the first time, and you can turn it OFF when use indoors.
² When the voltage is below the set value, it will buzzer with red LED light, pre-set value 3.3V.
² Push key which can change the voltage settings and save.
