FAQs about Use soldering iron to produce solar container lithium battery pack
Do you need a soldering iron to solder lithium batteries?
To solder lithium batteries properly, you need a very high-power soldering iron. This may seem paradoxical at first, but a high-powered soldering iron is able to perform soldering operations much quicker, resulting in less overall heat being imparted into the cells from the hot solder.
How do you solder a battery pack?
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.
What happens if you solder a lithium battery?
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.
Can You solder Li-ion batteries without a spot welder?
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.
