If you are going to solder lithium batteries, apply lots of flux to the cell before touching it with the soldering iron. This will ensure that the cell surface is in the best possible state to be soldered which will require less soldering time for a good connection. In this article, we will discuss how to solder lithium batteries.
Soldering Li-ion batteries such as 18650 or 21700 cells can be risky. If overheated, these cells can catch fire, or even explode. That’s why spot welding is always the preferred and safest method for making Li-ion packs. However, if you don’t have access to a spot welder, soldering is still possible with care and the right tools.
Step 1: Disassemble the battery pack, if you need to, so you can get to the cells. Step 2: Clean the cell ends so that when you solder, you will be able to make a secure, strong connection. Step 3: Turn on the soldering iron and allow it to heat up all the way.
The problem with soldering lithium batteries is that the heat from the soldering process damages the cells to some degree. Not only does it damage the cells, but it damages the cells to an inconsistent degree in most cases. This can cause the battery pack to come out of balance later on.
