5Pcs 3V37V To 5V 1A Lithium Battery Step Up Module Board Mini Mobile Power Boost Charger With Undervoltage Indication

Features : 1. Using high quality chips and expanding MOS tubes. 2. The output current is expanded to 1A, and the maximum output is 1.5A. The 2A Schottky diode is used to recharge the balance. 3. With the new scheme design, the circuit design does not require electrolytic capacitors and tantalum capacitors (the electrolytic capacitors have a short life and the tantalum capacitors are in danger of explosion). 3 ceramic capacitors (MCC) used in high-end circuits. 4. The same load indicator and undervoltage indication (when the battery voltage is less than 2.7V, the indicator will go out under load, when the battery voltage is greater than 2.7V with load, the indicator light is on, when there is no load, the indicator light is micro bright). 5. Ultra-small size, 14.1 18.8 5.5 mm. 6. The circuit conversion efficiency is high, the efficiency is higher than 90 procent and the efficiency of the single-cell lithium battery is also less than 80%. 7. Input low power reverse connection protection.
