Basic parametersVoltage: 51.2V is the nominal voltage of this lithium battery pack. In practical use, the terminal voltage of the battery will change with the charging and discharging process. During charging, the voltage will gradually increase to around 56V (full charge voltage), and during discharging, the voltage will gradually decrease. When the voltage drops to a certain level (such as around 42V), it usually indicates that the battery is approaching the end of discharge state.Capacity: 200Ah represents the rated capacity of the battery, which is the amount of charge that the battery can release under certain discharge conditions. Taking a constant current discharge of 20A as an example, theoretically it can last for 10 hours of continuous discharge. The actual available capacity of a battery may be affected by factors such as temperature, charge discharge rate, etc.Battery compositionBattery cell: usually composed of multiple lithium-ion battery cells connected in series and ...
