Can lithium-ion batteries be connected in parallel?

Connecting lithium-ion batteries in parallel or series is more complex than merely linking circuits in series or parallel. Ensuring the safety of both the batteries and the person handling them requires careful consideration of several crucial factors.

What is a series parallel battery?

There is series-parallel connected batteries. Series-parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system. For example, you can connect six 6V 100Ah batteries together to give you a 12V 300Ah battery, this is achieved by configuring three strings of two batteries.

When should a lithium battery be connected in series?

You should connect lithium batteries in series when your device requires a higher voltage than a single battery can provide. For example, if your device operates at 7.4V, connecting two 3.7V batteries in series would be appropriate. This setup is commonly used in applications like electric scooters, drones, or other high-voltage devices.

Can a lead acid battery be connected in parallel?
