Safety first

  • Before you begin soldering, note the following safety precautions:

  • Never solder on devices that are powered on or plugged in. Unplug, turn off, and remove power sources before soldering.

  • 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.

  • 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:

  • Drain the battery below 25%. This reduces the battery's ability to start a fire if it was short-circuited.

  • 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.

  • Whenever possible, create an indirect path by soldering connectors onto the battery and the circuit board. This reduces the chance of an unintentional short.

安全第一

开始焊接之前，请注意以下安全预防措施：

切勿在已通电或已插入电源的设备上进行焊接。焊接前，请拔下、关闭并移除电源。

不要直接焊接硬壳锂离子电池（例如 18650 电池）。烙铁产生的热量会损坏电池内部。请改用电池点焊机。

如果您正在焊接/拆焊锂聚合物电池线，请务必小心！焊料或工具很容易使电池短路，从而导致电池损坏和火灾危险。请遵循以下预防措施：

将电池电量降至 25% 以下。这样可以降低电池短路时起火的可能性。

每次只操作一根导线，以避免短路。用镊子夹住每根导线，控制其移动，确保不会短路。如果要从电路板上拆焊电池，在拆焊电线之前，使用平头切割器逐一切割每根电线，以隔离电池。

尽可能通过在电池和电路板上焊接连接器来创建间接路径。这样可以减少意外短路的机会。
