BICMDO 54.6V 2A Fast Charger for Super73 Z/S/R Series — 3‑Pin XLR, UL‑Certified Portable Adapter

This BICMDO 54.6V 2A fast charger is a compact, UL-certified power adapter designed to recharge 48V lithium battery packs used on Super73 Z, S and R series e-bikes via a 3-pin XLR connector.

Built to be portable and robust, this charger supports universal input voltage (100–240V), intelligent temperature control and multiple electrical protections. It reduces charge time compared with many stock chargers and is intended as a replacement or spare for supported Super73 models — not for Z1 / S1 or lead-acid batteries. The housing resists moisture, dust and vibration so it works in home, garage and travel environments.

How quickly will this charger refill my Super73 battery?

The BICMDO unit delivers 54.6V at 2A (maximum output around 163.8W), which shortens charging time versus many standard 1–1.5A chargers. Actual recharge time depends on your battery capacity and state of charge.

• 2A output provides faster top-up and overnight charging for most 48V Super73 packs.
• Intelligent current control reduces charging speed if the battery temperature rises.
• Compatible with typical Super73 battery capacities used in Z, S and R models.

Will this work with my bike and connector?

The charger uses a 3-pin XLR connector with a 0.34 in pin diameter and is tailored for many Super73 Z, S and R series lithium battery systems. It is important to verify your bike model and battery plug before buying.

• Designed for Super73 Z Series, S Series and R Series e-bikes (including Adventure and RX variants).
• Not compatible with Z1 or S1 models and not for lead-acid batteries.
• Confirm plug type and pin diameter to ensure a secure fit.

Is this charger safe for regular use and travel?

Yes — the charger carries UL certification, includes a flame-retardant aluminum case and several built-in safety systems to reduce risks like short circuits, overload and voltage surges. It also offers automatic temperature monitoring to limit operation under high heat.

• UL-listed with multi-layer protection for electrical faults.
• Aluminum housing resists heat and physical wear during transport.
• Supports 100–240V input for worldwide compatibility with appropriate plug adapter.

How portable and durable is the adapter for everyday riding?

The charger is engineered to be compact, quiet and weather-resistant so you can carry it in a backpack or trunk without worrying about vibration or light moisture. Its noise-free operation and dustproof design make it suitable for indoor and outdoor charging sessions.

• Compact size for easy storage alongside tools or accessories.
• Moisture-, dust- and vibration-resistant construction for varied environments.
• Quiet operation and automatic power adjustment for safer long charges.

Who is this for: Riders who own Super73 Z, S or R series e-bikes (including Adventure and RX variants) and need a reliable, faster replacement charger that is safe for travel and daily use. If you have a Z1 or S1, a different connector, or a lead-acid battery, choose a charger specified for those systems instead.
