Should you build a DIY battery pack with lithium-ion cells?

When constructing a DIY battery pack using **lithium-ion cells**, such as 18650 and 21700, safety should be your top priority. These cells are known for their **high energy density** and efficiency, but they also pose significant risks if not handled correctly.

What are the risks of constructing a lithium battery pack?

Problems can easily occur if the battery cells don’t uniformly emit power, the motor doesn’t withdraw the correct amperage, or the bus bars can’t handle the amps running through them. These are all risks when constructing your own lithium battery pack. Conversely, every single Battle Born Battery cell is tested under load before assembly.

Should you keep lithium ion batteries fully charged?

Storing lithium-ion batteries fully charged for long periods can increase internal resistance, shortening the overall life of the pack. Building a DIY battery pack can be a complex process, and there are several common mistakes that hobbyists often make:

Are lithium ion batteries dangerous?

Lithium-ion batteries contain various components that present different chemical hazards to workers, such as lammability, toxicity, corrosivity, and reactivity hazards. These chemicals may enter the workplace as raw materials or recycled materials.

Are lithium ion batteries flammable?

Some of these electrolytes are flammable liquids and requirements within OSHA’s Process Safety Management standard may apply to quantities exceeding 10,000 lb. Many of the chemicals used in lithium-ion battery manufacturing have been introduced relatively recently.

Are lithium batteries a fire risk?

First and foremost, lithium batteries pose a fire risk if not properly built because of their high energy density. If one of the cells fails, which can happen if it’s not made properly, the resulting heat can trigger a chain reaction called thermal runaway.
