The idea is that the P-channel FET will disconnect the battery from the load when a power source is connected to the charging chip. The TP4056 still charges the battery, but with no load. The load is directly from the power source powered.
Dual battery disconnect
Disconnect the battery if needed/desired. Connect the battery back first, then the solar panel last. By doing panel this way you are keeping stray and high voltages from hitting the panel and the controller. The battery protects from voltage spikes, is why you disconnect the solar while everything is still on the battery, then reconn the solar
What Happens if You Disconnect a Circuit from Its Positive
The positive terminal of a power source, such as a battery or a power supply, serves as the starting point for the flow of electrons in a circuit. When a circuit is complete, electrons flow from the positive terminal through the conductors and the load, and return to the negative terminal, thus creating a continuous loop that powers the connected devices.

Does A Car Battery Need To Be Disconnected Before Charging?
9 小时之前· Electrical Short Circuit: Charging a car battery while it remains connected can create an electrical short circuit. This occurs when electricity flows along an unintended path, resulting in sparks or damaging the battery and car''s wiring. Disabling power before disconnecting any battery type is vital. Always adhere to safety protocols and

An undervoltage lockout (UVLO) circuit is needed to disconnect the battery from the load. This may be implemented with a comparator, reference voltage, and a solid-state switch.
6 FAQs about [Power battery circuit disconnected]
Do rechargeable batteries need to be disconnected?
To prevent irreparable damage, rechargeable batteries need to be disconnected before going into deep discharge. For a 3.7V Li-Ion cell, this level is around 2.5V. An undervoltage lockout (UVLO) circuit is needed to disconnect the battery from the load. This may be implemented with a comparator, reference voltage, and a solid-state switch.
Can a relay disconnect a motor from a battery?
Assume that the load is a simple motor, can you please design a circuit with the use of a relay which disconnects the motor from the battery while being charged. If you are controlling the motor anyway, just do not turn it on. It will be disconnected from the battery.
What happens if a circuit is disconnected?
Having the circuit disconnected means it relies on you manually putting it in the charger and removing it, so why not have a plug in battery that you unplug from the circuit and plug it into the charger. Disconnected! Edit... How about a barrel jack and use the built in switch contact to disconnect the circuitry -Ve line.
When should you remove a battery from the load?
When the batteries are often fully discharged, their lives will be shortened and destroyed in a few weeks. Therefore, when your battery is weak or needs recharging it is best to remove your battery from the load. So today we are going to discuss “Low Battery Voltage Cuttoff OR Disconnect Circuit”.
Do I need to disconnect the load during charging?
Saw no need to disconnect the load during charging. Even if the charger didn't have enough output to power the radio, it would charge when the radio was off. OK, your application is a little different. Still, if you disconnect the load when the robot docks then how do you reconnect the load without having to do something manually?
What happens if a battery is misinserted with reverse polarity?
If a battery is misinserted with reversed polarity, the load may be damaged if it cannot tolerate negative voltages. A series diode is used to block the negative voltage. But, this diode dissipates power and drops significant voltage during forward operation.
