Official SUPER73 54.6V 5A High-Speed Battery Charger – Rapid Power Supply

High-Amperage Intelligent Charging

• Drastically Reduced Charge Times: Safely juices a standard 48V 20Ah (960Wh) battery pack from dead empty to absolute 100% saturation in roughly 3.5 to 4 hours (compared to a grueling 7–10 hours on a stock 2A charger).

• Integrated Active Cooling Fan: To manage the thermal demands of high-amperage power transfers, the aluminum housing features robust cooling fins and an internal automatic fan. The fan kicks on during active charging to keep internal components within safe operating margins.

• Dual-LED Smart Status Tracking: Features an intuitive visual monitoring system: a bright Red LED indicates active, high-current power transmission, while a crisp Green LED indicates the battery has reached its maximum top-off point or entered standby mode.

Strict 48V System Compatibility & Safety Mismatch Warnings

Because SUPER73 utilizes fundamentally different voltage platforms across its historical vehicle lineup, checking your bike’s system voltage is critical before plugging this in:

• 100% Native Compatibility: Engineered explicitly for 48V nominal lithium-ion systems that utilize a 54.6V maximum peak saturation threshold. This includes all versions of the S2, RX, RX Mojave, R Adventure, ZX, Z-Miami, and legacy S1 models.

• Critical Volts Mismatch Threat: This charger MUST NOT be used on newer SUPER73 A-Series models (such as the MZFT, M1D, or B1G frameworks). A-Series bikes utilize a higher-voltage 52V architecture requiring a 58.8V peak charger. Connecting a 54.6V charger to an A-Series battery will result in an immediate under-voltage safety lockout, preventing the pack from taking a charge.
