J5019 3V to 9V 12V Booster 3 With 1s BMS 3A

• Input voltage: 4.5-8V
• Output voltage: continuous adjustable 4.3-27V (Counter clockwise to boost voltage)
• Charging voltage: 4.2V
• Charging current: up to 1A
• Discharge current: the maximum 2A
• Output reference maximum current: 5V 1.4A, 9V 0.8A, 12V 0.6A
• Quiescent current: about 0.5 mA
• Overshoot protection: Yes
• Over discharge protection: None (also can be said yes, because 2V cut-off boost but does not block the output, output has 2V)
• Deadline boost:: 2V, depending on whether added the additional protection board
• Size: 3.3 x 2.3 x 0.9cm
• Connecting example, VIN + connect 5V solar panel, BAT + terminal can output 4.2V to charging 3.7V 18650 battery, OUT + side can output an adjustable voltage
• Can be used for multimeter, modified lithium battery charging

Features:

• 1. Micro USB input terminal with a female, can be directly input to do with the phone charger rechargeable lithium battery, And still retains the input voltage wiring pads, can be very convenient DIY
• 2. It can be used for voltage 3.6 3.7V, etc. 18650, polymer and other lithium battery charge and discharge protection
• 3. It Support charge discharge over current protection
• 4. It Supports simultaneous charging and discharging
• 5. Charge cutoff voltage: DC 4.2V±1%
• 6. Charging mode: linear charge
• 7. Working environment temperature: -20-85 degrees Celsius
• 8. For example: VIN+Port input 5V solar panels, BAT+port can output 4.2V to charge 3.7V 18650 battery Note: The OUT+Port can output an adjustable voltage
