| + | [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. | |
| [* black] If you're soldering lithium-polymer battery wires, follow these precautions as well: | |
| [* 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. *** | |
| [* 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_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. |
