The red LED lights up, indicating the battery is charging. 2. Cut-Off Mode: As the battery reaches the pre-set voltage threshold (adjustable using the potentiometer): The voltage at the transistor''s base increases, turning it on. This energizes the relay coil, switching it from NC to NO, cutting off the charging current to the battery.

Lithium battery packs have revolutionized how we power our devices by providing high energy density and long-lasting performance. These rechargeable batteries are composed of lithium ions, which move between the anode and cathode during charge and discharge cycles. such as the use of I1 constant current charging to the cut-off voltage
Power tools and medical devices drawing high current tend to push the battery voltage to an early cut-off prematurely. This is especially apparent at cold temperatures and in cells with high internal resistance.
The lithium battery industry has not only nominal voltage, but also float voltage and cut-off voltage, for 3.7V lithium battery, the float voltage is 4.2V and cut-off voltage is 2.5V, the actual situation will be slightly different
Cut-off Voltage: The cut-off voltage is the minimum voltage at which the battery is allowed to discharge during charging. Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging
In general the answer is no, there is no minimum supply current needed to stabilize the output of a battery. (Switching power supplies do have a minimum current.)

The cut-off voltage varies depending on the type of cell or battery being used, as well as its specific chemistry and construction. For example, a lithium-ion battery might have a cut-off voltage of around 3.0-3.3 volts per cell, while a lead-acid battery might have a cut-off voltage of around 1.75 volts per cell.

The cutoff voltage for a lithium battery is 2.75V, which means it is not suitable to discharge any longer if the lithium Battery Voltage reaches this value. This may result in irreversible damage to the partial capacity of the lithium battery or even serious damage to the battery itself. The rated voltage of a single lithium battery is generally 3.7V.
In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which battery discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved.
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the "charging cut-off current." II. Key Parameters in Lithium-ion Battery Charging
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
It seems standard for a lithium-ion charger to cut off the applied voltage when the CV-mode current draw dips below 0.1C (or thereabouts). Why is this necessary? Why can't the charger continue to apply 4.2V indefinitely? According to Battery University: Li-ion cannot absorb overcharge. When fully charged, the charge current must be cut off.
Batteries themselves have no cutoff values, managing circuitry around them has. Please edit your question its a little confusing, you can draw a battery to near zero volts if you continue drawing current out of it. Which will kill the battery Lithium, lithium ion (Li+) and lithium polymer (LiPo) batteries all have different characteristics.
