Ultra-Fast Charger Sur-Ron Ultra Bee 72V-84V 20A (Original Battery)

Sur-Ron Ultra Bee 125 Adjustable Ultra-Fast Charger – 72V (84V) – Adjustable 3A-20A

The 72V adjustable ultra-fast charger up to 20A Source'IT 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 integrated CAN BUS communication system.

Thanks to its adjustable charging current of up to 20A, it allows you to precisely adapt the charging speed to your usage. For a gentler daily charge, you can reduce the intensity, while the 20A ultra-fast mode allows you to quickly regain power when you need it.

At full power, this charger can recharge a 72V 55Ah battery in approximately 2h45 and a 72V 60Ah battery in approximately 3h00.

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

This charger delivers a perfectly regulated voltage of 84V, corresponding to the maximum charging voltage of the 72V (20S) lithium-ion batteries found in the Sur-Ron Ultra Bee.

🔒 Battery safety and preservation

The main advantage of an adjustable charger up to 20A is being able to choose the intensity according to your needs. It is therefore not necessary to systematically charge at full power.

For daily recharging when you have time, a lower intensity allows for a more gradual charge. When you want to get going quickly, the 20A mode allows you to exploit the full power of the charger and significantly reduce downtime.

A 20A charge represents approximately 0.33C for a 60Ah battery and approximately 0.36C for a 55Ah battery.

The active ventilation system maintains a stable charger temperature throughout the charging period, even at full power.

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

❓ FAQ – Sur-Ron Ultra Bee 125 20A Adjustable Ultra-Fast Charger

➡️ Is this charger compatible with all Ultra Bees?

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

➡️ Why don't conventional 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 necessary for the operation of original Ultra Bee batteries to allow the use of a powerful and reliable ultra-fast charger.

➡️ Is the charging current adjustable?

Yes. The charger allows you to adapt the intensity according to your needs. You can opt for a gentler charge when you have time or use up to 20A when you need an ultra-fast charge.

➡️ What is the charging time at 20A?

72V 55Ah battery → approximately 2h45
72V 60Ah battery → approximately 3h00

➡️ Is 20A mode suitable for the battery?

The 20A mode represents approximately 0.33C to 0.36C depending on the battery capacity. The charger is regulated, ventilated, and communicates directly with the BMS thanks to the integrated CAN BUS system.

➡️ Does the charger heat up at 20A?

High power naturally generates more heat than low-intensity charging. The aluminum heat sink casing and active ventilation are specially designed to maintain a controlled operating temperature even at full power.

➡️ Is it faster than the original charger?

Yes. With a maximum power of 20A, it significantly reduces charging time to approximately 2h45 for the 55Ah battery and 3h00 for the 60Ah battery.
