Fast Charger Sur-Ron Ultra Bee 72V-84V 15A (Original Battery)

Sur-Ron Ultra Bee 125 Fast Charger – 72V (84V) – 15A – Original CAN BUS Compatible

The 72V 15A Source'IT fast charger for Sur-Ron Ultra Bee 125 has been specially developed for the original 72V 55Ah and 72V 60Ah batteries found in Ultra Bee models. Unlike most 84V chargers on the market that are incompatible with the original electronic system, this charger is designed to work directly with the manufacturer's battery thanks to the integration of the CAN BUS communication system.

With its 15A power, it restores the performance of the manufacturer's charger while benefiting from modern electronics, enhanced cooling, and excellent charging stability.

Thanks to its ventilated aluminum casing and active ventilation system, the temperature remains perfectly controlled even during long full-power charging sessions.

This charger delivers a perfectly regulated 84V voltage, precisely matching the maximum charge voltage of the 72V (20S) lithium-ion batteries used in the Sur-Ron Ultra Bee.

🚀 Source'IT Innovation – Ultra Bee CAN BUS Technology

The original batteries of the Sur-Ron Ultra Bee use a CAN BUS electronic system that allows the BMS to communicate with the charger.

Without this communication, the battery automatically refuses to charge, making most universal fast chargers on the market incompatible.

After several months of research and development, Source'IT has developed its own solution integrating the Ultra Bee CAN BUS electronics directly into the charger.

This technology allows original Sur-Ron Ultra Bee batteries to be recharged without modifying the wiring harness, without an external adapter, and without interfering with the battery.

Each charger is individually configured to replicate the electronic dialogue expected by the Sur-Ron manufacturer's BMS.

🔒 Safety and battery preservation

A 15A charge represents approximately 0.25C for a 60Ah battery and approximately 0.27C for a 55Ah battery. These values are perfectly suited for the lithium-ion cells used in original Sur-Ron Ultra Bee batteries.

The active ventilation system maintains a stable charger temperature throughout the charging process.

To optimize your battery's lifespan, it is recommended to let it cool for about 30 minutes after use before starting the charge.

❓ FAQ – Sur-Ron Ultra Bee 125 Fast Charger

➡️ Is this charger compatible with all Ultra Bees?

Yes, with Sur-Ron Ultra Bees equipped with their original 72V 55Ah or 60Ah battery using the manufacturer's CAN BUS system.

➡️ Why don't classic 84V chargers work?

The Ultra Bee battery requires CAN BUS communication with the charger before allowing recharging. Without this communication, the BMS automatically blocks charging.

➡️ What does Source'IT technology offer?

Our system directly integrates the CAN BUS communication required for the operation of original Ultra Bee batteries to enable the use of a powerful and reliable fast charger.

➡️ Does the charger get hot?

Very little, thanks to its dissipating aluminum casing and active ventilation that ensure excellent cooling even during a 15A charge.

➡️ Is the charger faster than the original model?

It offers the same 15A charging power as the manufacturer's charger while benefiting from an optimized design and better thermal management.
