Can You solder lithium batteries with a soldering iron?

Work quickly, spending as little time as possible with the soldering iron on the cells. If you are going to solder lithium batteries, apply lots of flux to the cell before touching it with the soldering iron.

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.

Does a soldering iron heat up a battery?

The longer the iron is in contact with the battery, the more heat will build up. To accomplish this, use a powerful, temperature-controlled soldering iron. A less powerful iron won’t maintain its temperature as effectively since the heat will be absorbed while soldering large pieces of metal.

How much power do you need to solder a lithium battery?

To solder a lithium battery, you’re going to need at least 100 watts of power at the tip. Having triple-digit watts at your disposal is required to be able to get in there, form an excellent connection, and get you- quick. It may seem counter-intuitive, but the best soldering iron-to-solder lithium-ion batteries is going to be the hottest one.

Can You solder lithium-ion battery cells?

As you have probably heard by now, it's not ideal to solder lithium-ion battery cells. While a great solder joint can carry just as much current as a spot weld, if not more, the soldering process requires an intense amount of heat that does not dissipate quickly.

What wattage soldering iron should I use?

Use a high-wattage soldering iron (100 watts or more) to minimize the amount of time needed to be spent with the soldering iron in contact with the battery. Keep the soldering iron in contact with the battery for as short a time as possible to minimize heat damage. Unlike a spot welder, soldering releases a high amount of fumes.
