BICMDO 54.6V 3A Fast Charger for Super73 48V Lithium Bikes — 3-Pin XLR, UL-Certified Weather-Resistant Adapter

The BICMDO 54.6V 3A fast charger is a compact, UL-certified power adapter built to quickly and safely recharge 48V lithium battery packs on many Super73 Z, S, and R series e-bikes using a 3-pin XLR connector.

This charger is engineered as a replacement or spare for riders who need faster turnaround between rides without adding bulk. It delivers up to 163.8W of power from a universal 100–240V input, includes multiple safety protections and a durable weather-resistant case, and is optimized for travel and garage use. Before buying, check your Super73 model: this unit is compatible with many Z, S and R variants but not with Z1 or S1 models and it is not for lead-acid batteries.
