Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. You might even decide to reduce the target voltage to preserve the electrode. [pdf]

Here are the key differences between high voltage (HV) and low voltage (LV) energy storage batteries:Efficiency: HV batteries typically enhance overall system efficiency by reducing current, which lowers energy losses and conductor sizes1. LV batteries require higher currents to deliver the same power, potentially leading to increased energy losses1.Applications: HV batteries are often used in larger energy storage systems, such as grid storage and electric vehicles, while LV batteries are commonly found in smaller applications like home energy storage systems3.Cost: HV systems may have higher initial costs due to more complex components, but they can offer long-term savings through improved efficiency3. LV systems are generally less expensive upfront but may incur higher operational costs over time1. [pdf]

Lithium battery packs can be used in series to increase voltage while keeping the capacity the same. Here are some key points:Voltage Addition: When lithium batteries are connected in series, their voltages add up. For example, two 3.7V cells in series will provide 7.4V2.Capacity: The overall capacity (Ah) remains the same as that of a single cell in the series1.Balancing: It is crucial to balance the batteries in series by charging them individually to the same voltage to prevent issues3.Internal Resistance: Connecting batteries in series increases the internal resistance, which can affect performance1.Configuration: A common notation for battery packs is XsYp, where X is the number of cells in series and Y is the number of cells in parallel4.
