Green Cell ACEBIKE03 is an e-bike battery charger for bikes with a 36 V battery. Its 42 V, 2 A DC output is intended for charging that battery type.
The charger connects through a 3-pin plug, so check that the battery uses this connector. It accepts 100–240 V AC at 50/60 Hz, describing the input range for connecting it to a compatible power supply.
Use it for a 36 V e-bike battery when its connection is the matching 3-pin type; these specifications do not establish compatibility with other batteries or plug formats.
