Manage the constant current to constant voltage charging of a connected lithium battery Over-discharge protection - keeps your battery from being discharged below 2.4V, a healthy minimum voltage level for your batteryIf a connected battery has been discharged below 2.4V the module will cut output power from the battery until the battery voltage has been re-charged above 3.0V (the over-discharge release voltage), which at that time the module will again allow discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows charging of the battery to occur through the parasitic diode of the discharge control MOSFET (FS8205A Dual MOSFET). Overcharge protection - the module will safely charge your battery to 4.2V Overcurrent and short-circuit protection - the module will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs Soft-start protection limits inrush current Trickle charge (battery reconditioning) - if the voltage level of the connected battery is less than 2.9V, the module will use a trickle charge current of 130mA until the battery voltage reaches 2.9V, at which point the charge current will be linearly increased to the configured charge current.

This is a great way to switch on or off AC or DC loads using your Arduino. The relays are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals. This, along with the optical isolation, provides a total galvanic isolation between the input and output. The two grounds could be joined together if desired with the included jumper. The relay coils run on 5VDC, and the module has screw-terminal blocks for sturdy and reusable attachments for the external load. The signal and power inputs run through the male single-row header.

Using the module:Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module Connect cell to charge to B+/B- pads on the right-hand side of the module. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side Important! Disconnect load when charging The red LED indicates charging in progress, the green LED indicates charging has finished. Never charge your battery at a rate greater than 1C. 2. It is better thanthe charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, acurrent of 400mAh is enough. 3. The connection wire should not be too thick. 4. Make sure the connect point is good. 5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is a protection function, auto-subtract the charging current to avoid burn damage to thechip. 6. NO Reverse polarity.Features:Led indicator: red is charging Green is fully charged. Current Protection: Yes Inversed polarity: NO. Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy. Fully machinery automated processing, all patch parts manufacturing.
