battery voltage indicator display 5V to 7V
-
5V will shouw empty battery while n 7V it will show all bar lighting
-
Warm sound tips: This model is not waterproof. If it is used outdoors, please waterproof it, because electronic components should be used in a dry environment.
-
Lithium lead acid battery NiMH battery display board.
-
How to use: connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under the test. Digital tube displays real-time battery.
-
Power supply display parameter:
-
Battery voltage is greater than N × 3.3v, clear 1 mains supply (Note: N is the number of battery segments) (the following data is a reference value, there will be about 2% error range, do not shoot with high accuracy)
-
Battery voltage is greater than N × 3.5 v, bright 2 grids
-
Battery voltage is greater than N × 3.7 v, bright 3 grids
-
Battery voltage is greater than N × 3.9 v, bright 4 grids
-
Battery voltage is less than N × 3.3 v, a all four segments are off, which means that the battery is lower than 3.3 v. At this time, the battery is charged.
-
Digital tube color: the frame is red, the display is yellow, green and blue. The battery is fully charged.
