1, lithium battery only need to connect a 5V power supply, output B + B-connected battery can be. Charging red light, full of self-stop, charging green light finished.

2, for the lithium iron phosphate battery 3.6V, just soldering iron soldering between the two solder pad can be. Power supply battery connection method as described above. If you want to change back to charge 4.2V lithium battery, solder pad can be connected with solder back.

Description:

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.

Instructions:

With the circuit with a red, green or red and green light-emitting diodes, you need to weld to the circuit, as shown in the baby map, the longest foot in the middle of the long legs close to the chip, the shortest foot near the outside

Power termination 4.5-7V power supply, the current is greater than the charging current, this time the green light

Battery termination lithium battery or lithium iron phosphate battery, if the battery needs to charge, will turn red light

If you need to adjust the current, change the current you need in the current sense resistor. Sampling voltage 0.1V, current = 0.1 / resistance value

The circuit has been welded a 0.1 ohm resistor, there is a vacancy

The space is soldered to a 0.2 ohm resistor with a current setting of 1.5A

A 0.1 ohm resistor is soldered and the current is set to 2A

Remove the original R100 (0.1 ohms), solder a 0.2 ohm resistor, the current set to 0.5A

Charging current greater than 1A recommended installation of heat sink

If you need to charge an ordinary lithium battery (3.6 or 3.7V. Cut-off voltage of 4.2V) on the circuit board standard F point on the solder

If you need to charge lithium iron phosphate battery (3.2V. Cut-off voltage 3.6V) please remove the standard F solder on the solder

Features:

Full version of the use of precious metal ceramic capacitors, X7R temperature characteristics, performance + safety + stability far more than tantalum capacitors!

Copper strip 5A large current small volume inductance, fully closed magnetic low loss low interference!

Single-sided machine mounted, the overall 4 mm ultra-thin, small area of good heat dissipation, the back of copper easy to install and paste the heat sink

Based on DC-DC buck, the efficiency is much higher than the linear charging circuit, heat is also much smaller. Charge current 1A, but the input current is only about 0.7A is enough

Optional lithium iron phosphate battery or ordinary lithium-ion / lithium polymer battery, only a jumper can be set

Small size, 1 coin size, 1A charge without additional heat

With overheating protection, overheating will automatically reduce the current to prevent burnout

Full size high-precision resistors, full size 1210 Precious metal multilayer ceramic capacitors X7R The most stable temperature characteristics

Full of self-stop, two-color charging status indicator

Advantages:

Switch buck mode, the efficiency is higher than the linear charging circuit, heat is also much smaller. Charging current 1A, in the constant current full charge to maintain 1A. Do not need additional heat, reducing the impact of heat on the charging current. Reduce the charging time. Optional lithium ion lithium polymer battery or lithium iron phosphate battery, just a jumper can change the settings.

After the efficiency test will be described in detail, if the buyer's own test efficiency, do not recommend testing the battery side voltage, please note that skip the Rs sampling 0.1 ohm resistance test, the test input power close to the circuit board, reduce the length of the connection will be tested for efficiency Impact, it is recommended to increase the capacitance test at the input. Voltage and current test recommendations string accuracy of the ammeter is not recommended direct read power digital display. Current test can be directly connected in series with the battery, only need to ensure that the battery is less than 3.9V using a large range of ammeter test can be.
