How to solder 18650 battery nickel strip?

Soldering nickel strips to 18650 LiFePO4 cells can be done effectively with the right tools and steps. Here's a step-by-step guide:

Materials Needed:

- Soldering iron capable of 800-850°
- Wide soldering tip 5mm
- 60/40 rosin core solder
- Flux Pen
- Sanding Stick
- Tabbing, minimum 5mm
- Scissors
- Popsicle stick
- Combination Square
- Medium viscosity super glue
- Super glue accelerator

Steps:

1. Clean the Battery and Nickel Strip: Use a sanding stick to clean the surface of the battery and the nickel strip where you will be soldering.

2. Apply Flux: Apply flux to the area where you will be soldering. This helps the solder flow and adhere better.

3. Heat the Soldering Iron: Heat your soldering iron to around 800-850°.

4. Apply Solder: Apply a small amount of solder to the tip of your soldering iron, then touch the tip to the area where you want to solder. The heat will transfer the solder to the nickel strip and battery, creating a bond.

5. Cool Down: Allow the soldered joint to cool down before handling it.

Remember, safety always comes first! Always work in a well-ventilated area and wear appropriate safety gear. Practice makes perfect, so don't be discouraged if your first few attempts don't go as planned.
