New Energy Sources WhatsAppFor copper tabs I use RC battery bars (on the same page as the above link), I dont think it very economical but it works for me. For soldering direct to my Emoli cells I use silver bearing solder and a 140 watt solder gun. A hot solder gun is needed to solder direct to the battery.
New Energy Sources WhatsAppFor iron soldering on lithium-ion battery cells, the solder''s liquidus temperature should be below ca. 150 °C. Other heating techniques, such as laser soldering, seem more promising, because the heat input is rapid and extremely localized. As a conclusion, soldering is a good option for connecting battery cells.
