As shown in Figure 1, there are three main power supply overcurrent protection characteristics. The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics where a constant current range is used for charging batteries with a constant current.

The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.
It is not encouraged to attach the system load directly to Li-Ion batteries when using a stand-alone Li-Ion battery charge management controller with automatic termination feature. The charge may never end. Most Li-Ion battery chargers are based on Constant Current and Constant Voltage (CC-CV) modes.
Plugging in the board for charging and while in constant current mode, the USB supply is supplying around 300mA. This means, there is only 200mA available for the rest of the system. Implementing proper downstream system design is imperative to prevent power supply damage.
Constant current control power supplies and power supplies with a CVCC function are recommended for battery charging.
There is a 1000mAH lithium ion battery with a max charge rate of 0.5C (500mA), and max discharge of 1C (1A). The charging IC charges at a maximum of 300mA (this occurs in the constant current portion of the charge cycle). Depending on state, the load can use anywhere between 50mA and 500mA.
As shown in Figure 1, there are three main power supply overcurrent protection characteristics. The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics where a constant current range is used for charging batteries with a constant current.

Load Imbalance: Load imbalance may occur if the power supply cannot adequately share the load with the battery. This imbalance can cause the load to operate inefficiently or erratically. Electrical Engineering studies show that balanced loads are crucial for the longevity of electrical systems (L. Brown, 2021).
Power supplies are categorized in various ways, including by functional features. For example, a regulated power supply is one that maintains constant output voltage or current despite variations in load current or input voltage. Conversely, the output of an unregulated power supply can change significantly when its input voltage or load current changes.
By connecting the FET gate to the input power supply and a diode (normally a Schottky) in series, the system load takes power from the input supply while charging. The diode is required to prevent backfeeding of the battery to the …

Be prepared for power outages and off-the-grid outings with these expert-recommended portable power stations, also known as battery-powered generators.
Adding load sharing is in theory just three extra parts - a P-channel mosfet, a Schottky diode, and a resistor. But if it''s convenient to set things up so you can charge the batteries, or power the device, but not at the same time, then you don''t need load sharing.
By connecting the FET gate to the input power supply and a diode (normally a Schottky) in series, the system load takes power from the input supply while charging. The diode is required to prevent backfeeding of the battery to the input source. You can replace the diode with a MOSFET ideal diode to reduce the voltage drop.
An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
