Measure the open-circuit voltage of the battery. If it is lower than the following values, the battery is in undervoltage protection, and it refuses to charge: - 12V battery (10V) - 24V battery (20V) ------Possible Results------ Positive: Confirm that the battery is in undervoltage protection. Please follow the steps below to resolve the issue:
1. The battery is over-discharged, and the Battery Management System (BMS) is in undervoltage protection, preventing the battery from charging. 2. The BMS is in protection states such as low-temperature protection and over-current protection, causing the battery to be unable to charge.
when the gas gauge detects that the battery voltage is below 3.2 V, a warning is shown to the user (low battery) when the board is powered up. The system will go to sleep and the power consumption will then be quite low (100 to 500 uA). the board then relies on the battery's built-in safety PCM to cut-off the power if the voltage goes below 2.75 V.
Lithium-ion batteries can experience overvoltage and undervoltage effects. As noted in Figure 1, the operating voltage and temperature of the battery must be maintained at the point marked with the green box. If it is not, the cells can be damaged. Figure 1.

If you want to charge the batteries up to 2V, maybe set the voltage to 2V then so it stops the current once it reaches those 2V. Be wary though: if the battery voltage recovers on its own to higher than the set voltage, the PSU will be forced to sink current, which most don't support.
Unfortunately, when your Lithium-ion battery can not be fully charged, there could be a variety of reasons behind the problem. The issues might stem from a damaged battery or external factors unrelated to the lithium battery itself. It may require some trial and error as well as battery troubleshooting to uncover the underlying cause.

The Ultimate Guide to LiFePO4 Lithium Battery Voltage Chart
12V Like New Batteries ... A fully charged LiFePO4 battery may reach 14.6V, while a fully discharged one may drop to around 10V to 11V. Temperature and Load: These factors can cause minor deviations from the nominal voltage. 3. Examples of Nominal Voltages for Common Battery Types: LiFePO4 battery cell: 3.2V; Lead-acid battery cell: 2.0V (nominal), with a full charge …
[Solved] New Battery New Alternator Still Not Charging
You''re sure your alternator is working perfectly, and you just replaced your old car''s battery with a brand new one, and still, the battery isn''t charging; the problem could be from the new battery you got. They might have sold a bad battery to you, or probably something drained the battery. Sometimes, new components fail, so double-checking won''t hurt you at all.

If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles. Most EVs with LiIon batteries have less than 4.2V maximum charge voltage and recommend charging up to 80-90% of available capacity when possible. (Source: my ID.4 owners manual)
