This 54.6V 2A AC adapter is a replacement charger for 48V Li-ion e-bike battery packs using the STC-8205LD model. It accepts 100-240VAC at 50/60Hz for worldwide use and supplies a 54.6VDC output.

Who This Charger Suits and Who It Does Not

Riders with a Kunshan ST Electronics STC-8205LD charger requirement and a barrel-connector battery will find this a direct match. Buyers whose battery uses a different voltage, a higher current rating or a non-barrel connector should look elsewhere. The adapter is not suitable for 3A charge ports or for battery chemistries other than the specified Li-ion type.

Deciding Specification: 54.6V 2A Barrel Output

The single specification that decides compatibility is the 54.6V 2A DC output delivered through a barrel connector. Only battery packs designed for exactly this voltage, current and connector will charge correctly and safely with this adapter.
