The three main types of battery charging are constant current charging, constant voltage charging, and pulse width modulation. Constant current charging is the most common type of battery charger. It charges batteries by supplying a constant current to the batteries until they are fully charged.
RECONDITION is an option for the NORMAL and HIGH charging programs and can be selected by pressing the MODE button again after selecting the desired charging algorithm. During
There are many types of BMS (and many definitions of "normal"), but generally, in case of too high a charging current, a BMS will not limit the current to an acceptable level but simply stop the charging, and yes, this does protect the battery, but there will be no charging.

Battery level: Lastly, a crucial factor to remember is the state of charge of the battery before starting a charging session. The duration of a charging session will not be the same for an electric vehicle with a state of charge at 15% or at 65% when the charging session begins.
During battery charging, the current level determines how quickly a battery will charge. The appropriate charging current varies by battery type. While excessive heat from charging can harm battery life, overnight charging under normal conditions is generally safe. It''s Best to Let Batteries Fully Discharge Before Charging:

As a general rule, the maximum charging current of a battery is around 10 to 20% of its entire capacity. For example, if you have a 12V lithium battery with a capacity of 100 Ah, the maximum charging current should not be more than 20 Amps. It is better to speak with your supplier to determine your batteries' exact maximum ampere rate.
Once the voltage achieves its maximum, charge cut-off voltage, the circuit switches to constant voltage charging mode. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage. When the batteries are fully charged, the charging current drops to 0.1C.
The larger the capacity of the battery, the higher the charge current is usually. Similarly, the higher the charging ratio, the higher the charging current and the shorter the charging time. For internal resistance, the greater the internal resistance, the lower the charging current.
