Can lithium-ion batteries be connected in parallel or in series?
Connecting lithium-ion batteries in parallel or in series is not as straightforward as a simple series-parallel connection of circuits. To ensure the safety of both the batteries and the individual handling them, several important factors should be taken into consideration.
Can two batteries be connected in parallel?
The parallel connection of two identical batteries allows to get twice the capacity of the individual batteries, keeping the same rated voltage. Following this example where there are two 12V 200Ah batteries connected in parallel, we will therefore have a voltage of 12V (Volts) and a total capacity of 400Ah (Ampere hour).
