NO. 序号	Item 项目	Content 内容
2.1	Cell Technology 电芯类型	EVE 50E
2.2	Nominal Voltage 额定电压	48V
2.3	Nominal Capacity 额定容量	Nominal:20Ah (by standard charge and discharge) 典型值：20Ah（标准充电、放电） Minimum:18.62Ah(by standard charge and discharge) 最小值：18.62Ah（标准充电、放电）
2.4	Standard Charge 标准充电	Constant Current and Constant Voltage (CC/CV) 恒流恒压 Current = 2000mA 电流=2000mA Voltage = 54.6V 电压= 54.6V End Current =400mA 截止电流 =400mA
2.5	Max. Constant Charge Current 最大持续充电电流	3A
2.6	Spark Prevention of Charging 充电防打火	Under specific conditions (overcurrent, short circuit, overdischarge protection, etc.), the charger that needs to detect the voltage of the charging port is not supported. The pulse charger needs to be confirmed before using, otherwise the battery protection cannot be released.特定状态时（过流、短路、过放保护等），不支持需检测充电口电压的充电器，脉冲充电器需确认使用，否则可能会导致电池保护不能释放。
