Solder with the Qianli Spot Welder. Note that one end of the spot welding pen is placed on the conductor material (copper). The other end is placed at the point to be soldered.

Folder well the tabs after soldering. Apply the protection tape.

Put on the protection bracket. Wrap another layer of protection tape on the outside.

Connect the programmer to the laptop.

Then connect the battery to the programmer. Click reading. Recalibrate the cycle times and battery efficiency.
