If you limit your charging voltage to 4.20V then yes, it should be sufficient to charge the battery (very slowly). You should also ensure that if the charger is not powered it won''t discharge the battery (eg. disconnect the charger when it is not powered, or put a reverse current blocking diode in the charging circuit).
If you have a Li-ion battery that has been deeply discharged, the battery can be charged slowly, and one can restore the charge to the battery. To implement this method, you can connect a multi-meter between the battery and the charger.

Charging lithium batteries at a rate of no slower than C/4 but no faster than C/2 is recommended to maximize battery life. The charge cutoff current is typically determined by the charger, and the voltage range should stay within the limits
A lithium battery charger is just a fixed voltage power supply with current limit. Sure - you can set the voltage wrong but if you know what you are doing and are careful, you can charge a lithium battery WITH A BMS safely with a bench supply.
You can slow charge a Lithium cell, but you cant not trickle or float charge one. What the poster meant by ''slow charge'' is the constant current charge that is applied as a float charge to lead acid, NiCad, and even NimH cells. Lithium cell will NOT tollerate this float charge.
Because of difficulties in detecting full charge with nickel-based batteries, I recommend charging only lead and lithium-based batteries manually. Before connecting the battery, calculate the
Lithium specifics are as follows, do not charge them when they are below freezing, if possible only charge them above 40F. LiFePO4 batteries have a self-discharge rate of 1-3% per month, best thing to do is leave them around 80% and disconnect them (make sure there is no power being used) since they will be at 50% 10 months later, the can still
It is generally recommended to charge lithium-ion batteries at rates between 0.5C and 1C for optimal performance and longevity. A lithium-ion battery is considered fully charged when the current drops to a set level, usually around 3% of its rated capacity.
No, an adjustable constant voltage supply can''t be used to charge batteries, because a power supply is not a charger. A power supply like the LRS-350-24 tries to keep the output supply voltage constant. For example you can set it to 26V. A somewhat empty LiFePo4 could have 22V.
A faster rate causes more unevenness; a lower rate causes less unevenness. If a battery heats up while getting charged, it is more malleable, and accordingly more susceptible to damage. Therefore, no matter how slowly you charge a lithium ion battery, over time its internal organization decreases, and it loses capacity.
Running a lithium battery pack at extreme SoC levels – either fully charged or fully discharged – can cause irreparable damage to the electrodes and reduce overall capacity

To effectively tackle slow charging issues with your lithium-ion battery, diagnosing the problem accurately is essential. Here''s how you can identify potential causes: Inspect Your Charger and Cable: Check for visible
Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged. Many
Most ebike chargers charge batteries to 100%, there are a few exceptions like the Luna Advanced ebike chargers which allow you to charge to 80% or 90% and the Grin Cycle Satiator which allows you to charge to any voltage but they are the exceptions to the rule. All lithium chargers that I know of charge with a Continuous Voltage Variable Amperage style.

To effectively tackle slow charging issues with your lithium-ion battery, diagnosing the problem accurately is essential. Here''s how you can identify potential causes: Inspect Your Charger and Cable: Check for visible wear and tear on your charger and cable.
Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated.
If you have a Li-ion battery that has been deeply discharged, the battery can be charged slowly, and one can restore the charge to the battery. To implement this method,

Charging lithium batteries at a rate of no slower than C/4 but no faster than C/2 is recommended to maximize battery life. The charge cutoff current is typically determined by the charger, and the voltage range should stay within the limits to prevent damage.
I''m trying to charge the pack using a 25.5V dc power source as specified by the BMS manufacturer, using a 500W power supply I had which is fairly similar to this one. The BMS are connected parallel to each other. Technically, the system works. However, the charge rate is very, very slow - to the tune of plugging it in at 22.2V, and
Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged. Many believe that

This is when the voltage is kept constant and the current slowly falls to zero. DIY Battery Chargers Vs Buying A Charger. When you buy a charger you are limited to that charger''s specific voltage and current level.
If you have a Li-ion battery that has been deeply discharged, the battery can be charged slowly, and one can restore the charge to the battery. To implement this method, you can connect a multi-meter between the battery and the charger. A slow current setting should be selected, and that is it.
The slow charging method is by far the easiest and safest way to solve lithium battery problems. You have to use the same battery to apply only a low current for the slow charge. The slow charge method is a docile approach in which you gradually restore the battery’s functionality.
A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
The slow charge method is a docile approach in which you gradually restore the battery’s functionality. This will not let the battery load much so that it might not get damaged beyond repair. If you have a Li-ion battery that has been deeply discharged, the battery can be charged slowly, and one can restore the charge to the battery.
Charging lithium batteries at a rate of no slower than C/4 but no faster than C/2 is recommended to maximize battery life. The charge cutoff current is typically determined by the charger, and the voltage range should stay within the limits to prevent damage.
Swelling is one of the very first signs that a lithium-ion battery cannot be fixed. This swelling is a sure indication the battery has internal damage, such as too much gas or an overheating of the battery. If your battery is swollen, do not use it or charge it. Trying to repair a battery in this condition can cause it to break or even explode.
