Selection guide
Confirm the motor controller and charger voltage before comparing capacity. Continuous and peak current, target range, enclosure dimensions, mounting, connector, locking or service method and the complete bike's weight constraints should be reviewed together.
Confirm nominal voltage, usable capacity, continuous load, peak demand and charging limits.
Check enclosure space, mounting, terminals, connectors, cable routing and service access.
Share application, environment, quantity, compliance and integration requirements with engineering.

用电压平台、Wh 续航、电流、车架安装和充电器完成更换前核对。
只有控制器、电机、显示器和充电器都支持 48V 才可以。先读取这些部件的最高输入电压和低压截止值;若任一部件仅支持 36V,直接升级电池可能损坏设备。
先把容量换算为 Wh,再除以车辆实际 Wh/km。公式为“能量 Wh = 标称电压 V × 容量 Ah”,“预估里程 km ≈ 可用 Wh ÷ 实测 Wh/km”;实测值应包含骑手体重、助力档位、坡度、速度、温度和胎压。
电池的持续和峰值输出必须不低于控制器实际需求。记录控制器额定及最大电流、峰值持续时间和低压截止,再检查 BMS、连接器、线束和保险;只看电机标称功率可能低估起步和爬坡电流。
使用尺寸图和安装点核对,不能只看外壳照片。测量可用长宽高、滑轨或螺孔、锁止位置、出线方向、充电口、拆装路径和允许重量,并给连接器预留弯曲空间。
仅在电压、充电曲线、电流、连接器和极性全部匹配时可以。尤其要核对充满电压,而不是只看“36V”或“48V”标签;外形相同的插头也可能极性或针位不同。
