Official SUPER73 S1 Replacement Battery (48V 14.5Ah) – 700Wh

Bring your classic urban cruiser back to peak performance with the genuine OEM SUPER73 S1 48V 14.5Ah Replacement Battery. Engineered with high-grade lithium cells configured to output a massive 700 Watt-hours (Wh) of energy, this locking power pack acts as a direct hot-swap replacement for a degraded original battery or functions perfectly as a backup pack to instantly double your travel range on long-distance commutes.

Genuine Factory Engineering & Safety

• Convenient Removable Form Factor: Slide the lock, lift the pack off its cradle, and carry it inside to juice up at your desk or home without needing to drag your entire bike near an outlet.

• Complete Security Key Assembly: Shipped with 2 matching physical keys to engage the heavy-duty locking pin, keeping your power pack securely tethered to your downtube frame when parked out in public spaces.

• 3-Pin Multi-Amp Charger Flexibility: Fully regulated to handle safe power input transmission from standard factory SUPER73 3-pin chargers across 2A, 3A, and high-speed 5A fast-charger variations.

⚠️ Important Packing Note: This item includes the standalone battery pack, integrated decals, and locking keys only. The matching lower Battery Mounting Baseplate and the AC Charging Wall Adapter are sold separately.

Critical Cross-Model Compatibility Notice

Because SUPER73 utilizes fundamentally distinct voltage structures, electronic controllers, and physical track plates across its generation lineages, pay close attention to your specific bike model before purchasing:

• 100% Compatible Units: Mapped exclusively to fit the classic SUPER73-S1 framework structure.

• Incompatible Units: This unit will not fit or power newer 48V models like the ZX or Z-Miami (which use distinct sleek longitudinal casings), nor will it interface with 52V systems like the modern A-Series or high-voltage R/S2 platforms.

Dual-Battery Operation Warning

We strongly advise against utilizing third-party “Y-splitters” or modifications to run two of these packs simultaneously to your motor controller. Combining batteries with different internal cycle wear or mismatched firmware states can bypass safe battery management system (BMS) limits, risking severe overheating, permanent cell degradation, or immediate electrical hardware failures. To double your range safely, store your second pack securely in a cargo bag and swap it onto your stock bracket manually once the first pack empties.
