Fly for Fun

Feature: 1. Super thin Type Electricity Display: 5 Pieces indicator lamps. 2. Wide Application Fields:lithium battery pack. 3. Using Method: connect display board positive and negative terminals with tested battery positive and negative port. 4. Slightly hold down the red button with your finger, then lights will be on and show real-time battery electricity quantity.(Note: The first light is for power Indicator light) 5. Release the finger, the lights will be off after 3-5 seconds delay, it completely does not consume electricity when in the static state. 6. With anti-transposition function, even if the positive and negative ports are connected with wrong direction and it will not burn, simply correct it. Lithium Battery Pack Display Electricity Quantity Parameter: (note: N represents battery quantity) 1. When battery voltage is over N*3.2V, it will illuminate 1 block electricity quantity. 2. When battery voltage is over N*3.4V, it will illuminate 2 blocks electricity quantity. 3. When battery voltage is over N*3.6V, it will illuminate 3 blocks electricity quantity. 4. When battery voltage is over N*3.9V, it will illuminate 4 blocks electricity quantity. 5. When battery voltage is less than N*3.2V, 4 blocks display will be off; it represents battery is less than 3.2V, and you can charge the battery.
