• Dual display power + voltage, up 8 color bars display battery power, downstream (display battery voltage)
• It can be used in a wide range of applications, such as 18650 , polymer pack, - battery, electric vehicle battery, nickel-hydrogen battery, etc.
• Usage: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test. The digital tube displays the real-time battery power (do not the positive and negative electrodes, otherwise it will be directly damaged )
• Working current: 5-15ma, the lower the battery voltage, the smaller the current.
• 8-band power resolution: 10% 25% 40% 50% 60% 75% 90% 100%. More voltage calculation, the same principle as the electric vehicle's power display.
