Frequently Asked Questions About how big a soldering iron should i buy to make a solar battery cabinet lithium battery pack

Find answers to common questions about energy storage cabinets, outdoor cabinets, telecom cabinets, battery systems, and industrial BESS solutions in South Africa.

Do I need a soldering iron to build a battery pack?

Whether you are building a battery pack with a soldering iron or using a spot welder, you are going to need a soldering iron. While we do cover how to build a battery pack from 18650 cells using spot welding vs soldering methods, we strongly recommend going the spot-welding route.

How do you solder a battery with a soldering iron?

Try to use a thicker soldering iron tip as it transfer heat more effectively. Quickly tin both terminals (apply a small blob of solder to each battery terminal). The goal is to get in and out fast — ideally in under a couple of seconds. If the iron is in contact with the battery for too long, heat will build up and it becomes risky.

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.

How do you sand a radio battery before soldering?

Sandpaper or file: To roughen the battery contacts. Before soldering, it’s a good idea to discharge the cells to around 3.0V per cell. Lower voltage = less stored energy = reduced fire risk. You can do this using a 18650 battery holder, like the one comes with any Radiomater radio.
