| [title] Safety first | |
| [* icon_note] Before you begin soldering, note the following safety precautions: | |
| [* icon_caution] Never solder on devices that are powered on or plugged in. Unplug, turn off, and remove power sources before soldering. | |
| [* icon_caution] Don't solder directly to hard-shell lithium-ion batteries (such as 18650 cells). The heat from the soldering iron will damage the battery internals. Use a battery spot welder instead. | |

| - | [* icon_note] ***Work with one wire at a time*** to avoid short circuits. Use tweezers and hold each wire to control its movement and ensure it doesn't short. |
| + | [* icon_caution] ***Be extremely careful if you're soldering/desoldering lithium-polymer battery wires!*** You can easily short the battery with solder or your tools, resulting in battery damage and a fire hazard. Follow these precautions: |
| + | [* icon_note] ***Drain the battery below 25%.*** This reduces the battery's ability to start a fire if it was short-circuited. |
| + | [* icon_note] ***Work with one wire at a time*** to avoid short circuits. Use tweezers and hold each wire to control its movement and ensure it doesn't short. If you're desoldering a battery from a circuit board, use flush cutters to ***cut each wire one-at-a-time*** to isolate the battery before you desolder the wires. |
| [* icon_note] Whenever possible, create an indirect path by soldering connectors onto the battery and the circuit board. This reduces the chance of an unintentional short. | |
| - | [* icon_note] If you're desoldering a battery from a circuit board, use flush cutters to ***cut each wire one-at-a-time*** to isolate the battery before you desolder the wires. This prevents accidental shorts and the battery from heating up from the hot soldering iron. |
