For the charging side of the equation, see our companion article on lithium-ion battery charger circuit design and load sharing.

Lithium Ion batteries are one of the best technologies to use for a battery in portable electronics. They can also be one of the most dangerous if safety precautions are not taken. In this video I go into understanding what UL listing for a product means, and how it can help increase the safety of a product. Using this knowledge I show several battery protection techniques to help protect your circuit from catastrophic failure.

We design custom battery management systems that incorporate these safety considerations from the ground up.

Battery safety is critical in any product design. At MicroType Engineering, we specialize in custom electronics design including battery management systems with proper safety protection built in. Contact us to discuss your project.
