Electrical Safety First: Lithium-ion batteries

Safety tips

Lithium-ion batteries have become widely used in a range of items including mobile phones and tools through to larger items such as electric bikes, e-scooters and electric vehicles.
Lithium-ion batteries have the ability to store an enormous amount of energy in a very small space; this guide concentrates on portable lithium-ion batteries such as those that you can charge in your home.
The ability to store an enormous amount of energy in a very small space is also one of the main disadvantages of lithium-ion batteries which can lead to risks of fire and explosion if they are not stored and charged safely. When used properly, lithium-ion batteries are convenient and safe to use but batteries can present a fire risk when over-charged, short-circuited, or if they are damaged.

Charging them safely is really important.
