Definition of Series and Parallel Connection of Lithium Batteries
The process of assembling lithium cells together is called PACK, which can be a single battery or a lithium battery pack connected in series or parallel. The lithium battery pack usually consists of a plastic case, PCM, cell, output electrode, bonding sheet, and other insulating tape, double-coating tape, etc.
A custom 18650 battery pack is a versatile energy storage solution, commonly used in applications like electric vehicles and portable electronics. It typically consists of multiple 18650 lithium-ion cells connected in series and parallel configurations to achieve the desired voltage and capacity. Proper design and management ensure safety …
Electrical Equivalent Circuit Models of Lithium-ion Battery
Lithium-ion batteries have a terminal voltage of 3-4.2 volts and can be wired in series or parallel to satisfy the power and energy demands of high-power applications. Battery models are important because they predict battery performance in a system, designing the battery pack and also help anticipate the efficiency of a system [1, 2].

• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.
Series connections increase voltage, while parallel connections increase capacity.Voltage Compatibility Ensure that the voltage of your battery pack is compatible with the voltage requirements of your devices or system. Make sure you check compatibility at the highest charge and lowest discharge voltages.

It involves aligning the total voltage output of the battery pack with the device or system it powers, ensuring compatibility and optimal functionality without under or over-voltage issues. ... For instance, if four 18650 cells with a nominal voltage of 3.7 volts are connected in series, the total voltage output would be 14.8 volts (3.7V * 4 ...
Overview of cell balancing methods for Li-ion battery technology
Li-ion batteries are influenced by numerous features such as over-voltage, undervoltage, overcharge and discharge current, thermal runaway, and cell voltage imbalance. One of the most significant factors is cell imbalance which varies each cell voltage in the battery pack overtime and hence decreases battery capacity rapidly.
The following formula applies to series circuits: (V total = V 1 +V 2 etc.). This will provide you with extra voltage for the load, but no extra current (I total = I 1 = I 2 …
