Sur-Ron Ultra Bee 72V-84V 10A Charger (Original Battery)

Sur-Ron Ultra Bee 125 Adjustable Charger – 72V (84V) – 3A to 10A with OLED Screen (Compatible with original CAN BUS battery)

The 72V – 3A to 10A adjustable charger for Sur-Ron Ultra Bee 125 is specifically designed for Sur-Ron Ultra Bee models equipped with their original 72V 55Ah or 60Ah battery. It allows for a stable, secure, and perfectly adapted charge for the 72V architecture of this high-end electric motorcycle.

Unlike the majority of chargers on the market that are incompatible with original Ultra Bee batteries due to the CAN BUS communication system, this model has been specifically developed to work with the manufacturer's Sur-Ron battery.

When charging overnight and you are not in a hurry, you can charge slowly at 3A or 5A, and when you need to recover range quickly, you can go up to 10A. The ability to adjust the charging intensity also helps preserve battery life while maintaining fast charging when necessary.

Thanks to its aluminum housing with active cooling and quality electronics, this charger delivers a perfectly regulated 84V voltage, limiting heat and ensuring excellent reliability.

Its integrated OLED screen displays the charged capacity, battery voltage, and selected charging current in real time. Adjustments are made simply via a rotary dial.

🚀 Source'IT Innovation – Ultra Bee CAN BUS Integration

The original batteries of the Sur-Ron Ultra Bee use a CAN BUS communication system between the charger and the battery's BMS. Without this communication, the battery will simply refuse to charge.

After several months of development, Source'IT has developed its own electronic solution that directly integrates the CAN BUS unit with the charger.

This innovation allows for the use of a fast and adjustable charger while maintaining total compatibility with the manufacturer's battery, without any modifications to the motorcycle, external adapters, or intervention on the electrical wiring harness.

Each charger is assembled and configured to reproduce the electronic dialogue expected by the original Sur-Ron Ultra Bee BMS.

🔒 Safety and compatibility

Is this charger safe for the Sur-Ron Ultra Bee?
Yes. A 10A charge represents less than 0.2C on a 55Ah or 60Ah battery, which remains very comfortable for the modern lithium-ion cells used by Sur-Ron.

The adjustment also allows for a gentler charge at 3A or 5A when speed is not necessary.

Tip: let the battery cool down for 30 to 60 minutes after use before charging at 10A.

❓ FAQ – Sur-Ron Ultra Bee 72V adjustable charger

Is this charger compatible with the original Ultra Bee battery?

Yes. It is specifically developed for original Sur-Ron Ultra Bee batteries equipped with the CAN BUS system.

Why do standard chargers not work on the Ultra Bee?

The original battery requires CAN BUS communication with the charger before authorizing charging. Without this communication, the BMS completely blocks the charge.

How did Source'IT solve this problem?

We developed a solution that directly integrates the CAN BUS communication system necessary for the operation of the original Ultra Bee battery.

Is the 10A mode dangerous for the battery?

No. A 10A charge remains very reasonable for a 55Ah or 60Ah battery and stays well within the recommended operating limits.

Does the charger have active cooling?

Yes. It features active ventilation combined with an aluminum heat sink housing to maintain a stable temperature even during long charging sessions.
