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

Adjustable Sur-Ron Ultra Bee 125 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 provides stable, secure, and perfectly adapted charging for the 72V architecture of this high-end electric motorcycle.

Unlike most chargers on the market which 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 not in a hurry, you can charge quietly at 3A or 5A, and when you need to quickly regain range, you can go up to 10A. The ability to adapt the charging current also helps to further preserve battery life while maintaining fast charging when needed.

Thanks to its aluminum casing with active ventilation and high-quality electronics, this charger delivers a perfectly regulated 84V voltage, limiting heat build-up and ensuring excellent reliability.

Its integrated OLED screen displays the charged capacity, battery voltage, and selected charging current in real time. Adjustment is easily done via a rotary knob.

🚀 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 simply refuses to charge.

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

This innovation allows the use of a fast and adjustable charger while maintaining full compatibility with the manufacturer's battery, without modification of the motorcycle, without external adaptation, and without intervention on the electrical wiring.

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 for a 55Ah or 60Ah battery, which is 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 – Adjustable Sur-Ron Ultra Bee 72V 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 don't classic chargers 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 recharging.

How did Source'IT solve this problem?

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

Is 10A mode dangerous for the battery?

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

Does the charger have active cooling?

Yes. It has active ventilation combined with a heat-dissipating aluminum casing to maintain a stable temperature even during long charging sessions.
