When charging, use a bulk charge process first to reach the target voltage quickly. After that, a float charge is used to maintain the battery without overcharging, usually around 3.4 V per cell. Avoid lead-acid chargers, as they can damage LiFePO4 batteries. There is so much about different battery voltages and how their state of charge relates to their voltage
As an example, the diagram below compares the discharge curves between a lead battery and a Lithium-Ion battery. Lithium LiFePO4 vs Lead dicharge curve It can be seen that lead-acid batteries have a relatively linear curve, which allows a good estimation of the state of charge : for a measured voltage, it is possible to estimate fairly precisely the value of the associated SoC.

The lithium battery charging curve illustrates how the battery's voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.
This charge curve of a Lithium-ion cell plots various parameters such as voltage, charging time, charging current and charged capacity. When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method.
The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).
The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve. To understand the discharge characteristic curve of a battery, we first need to understand the voltage of the battery in principle.
This discharge curve of a Lithium-ion cell plots voltage vs discharged capacity. A flat discharge curve is better because it means the voltage is constant throughout the course of battery discharge.
During the charging process of a lithium battery, the voltage gradually increases, and the current gradually decreases. The slope of the lithium battery charging curve reflects the fast charging speed., the greater the slope, the faster the charging speed.
