Generally, the discharge rate of lithium-ion batteries is recommended to be between 0.2C and 1C. Therefore, for a 100ah lithium battery, the discharge current is preferably between 20a-100a. Beyond this value, the current should be exceeded, which can be damaging to the battery. [pdf]
[FAQS about 48v lithium battery pack discharge current]
A high voltage at one end of a lithium battery pack can indicate several issues:Voltage Imbalance: Lithium-ion batteries in series can experience voltage imbalances, where one cell may charge or discharge differently than others, leading to a higher voltage at one end1.Discharge Characteristics: The voltage of lithium-ion batteries typically drops gradually as they discharge, with a steep drop towards the end of the discharge cycle. A high voltage at one end may suggest that the battery is not discharging evenly2.Fluctuations During Charge/Discharge: The voltage can fluctuate significantly during charging and discharging, influenced by various factors, which may lead to one end showing a higher voltage3.It's important to monitor and manage battery voltage to prevent damage and ensure optimal performance.
