1. PCB size:21.5*14.5*4.2mm
2. Input voltage: DC 4.5-9V(Recommended not to exceed 7V)
3. Output voltage: DC 4.2V/3.6V(default 4.2V)
4. Output current: 1A(Default max)
5. LED Indicator: Charging-Red/Green Flashing,Charged-Green
6. Features:Charging for Lithium battery(4.2V) and Lithium iron phosphate battery(3.6V)
7. Switch mode:
1>. F Welding point ON for Lithium battery and output 4.2V
2>. F Welding point OFF for Lithium iron phosphate battery and output 3.6V
8. Adjust output current(need to modify two resistance value on mark "SANYA"):
1>. Default weld 1pcs R100(0.1ohm) resistor and output 1A(max)
2>. Welding 1pcs 0.2ohm resistor next to R100 and output 1.5A(max)
3>. Welding 1pcs 0.1ohm resistor next to R100 and output 2A(max)
4>. Removed R100 and welding 1pcs 0.2ohm resistor on its place and output 0.5A
5>. It requires additional heat sink if output current more than 1A.
