2 Lithium Ion Batteries Charging with TP4056 Charging Module || #tp4056 ...

Components required: 1. Prototyping board. 2. TP4056 charging module(Type-C). 3. DPDT Push switch/Self-locking switch. 4. 2 x 18650 Lithium-ion batteries. 5. Battery holder. 6. Jumper pin. 7. Wires. In this video, I am going to show you how to charge 2 lithium-ion batteries with only 1 TP4056 charging module, instead of using 2 modules. This video is very useful for your robotics projects. Please follow the steps and instructions Step 1: Take the piece of the prototyping board for soldering the components. Step 2: Place the TP4056 charging module on the top of the PCB board and solder in the middle of the board. Step 3: Place the DPDT Self-Locking Switch and place down the side of the TP4056 charging module and solder as shown in the video or circuit diagram.

Step 4: Now solder the middle pins of the switch to the battery terminals of the charging module "+" to the left middle pin and "-" to right middle pin. Step 5: Now Take a twisted pair of wires and solder the red wire to the bottom left pin and solder the black wire bottom right pin of the switch, and take another twisted pair of wires and solder the red wire to the top left pin and solder the black wire to the top right pin. Step 6: Now Solder the wires to the batter holder/batteries as shown in the image.

Step 7: Now Test the Battery's voltage, connect the charger type-C to the Charging module, and press the switch to charge batteries individually. Step 8: Now Connect the Jumper pin and connect the wires in the series to the batteries as shown in the video or circuit diagram. Step 9: Jumper is to connect the 2 batteries in series to get high voltage from the batteries. If we remove the jumper we won't get high volts and series the connection will be disconnected.

Step 10: If we want to charge the batteries, we need to remove the jumper pin for safety and disconnect the batteries. 

 Note: Please don't connect more than 2 batteries to the circuit, it may explode or fire.
