Charging a Lithium battery with a higher Lead-Acid charging voltage will cause the Lithium Battery's Battery Management System (BMS) to self-protect and disconnect the battery from the charging source. Additionally, determining state-of-charge and charge termination using voltage is more difficult with Lithium than with Lead-Acid.
Traditional fast charging methods usually entail charging the battery with high currents. Nonetheless, prolonged high-current constant charging can cause a progressive rise in battery temperatures. Excessive temperature can shorten the lifespan of LIBs, leading to decreased battery performance and driving range .
Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.
This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery's capacity over time.
It’s a common belief that the voltage of a lithium-ion battery can accurately indicate its charge state. However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature.

Balance Current: This is the current used to equalize the voltage across all cells in a battery pack during balance charging. Higher balance currents allow the charger to balance the cells more quickly, reducing overall charging time. Look for chargers with higher balance current ratings to enhance charging efficiency.
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.
