Sur-Ron Light Bee Custom 72V-84V 10A Charger – Source'IT

⚡ Adjustable 72V – 84V 3A to 10A Charger for Modified Sur-Ron Light Bee (OLED screen + knob)

This 72V – 3A to 10A adjustable charger (84V output) is designed exclusively for modified Sur-Ron Light Bee bikes with custom controllers (Torp TC500, TC1000, SinTech, ASI, Nucular, and other high-performance configurations). It allows for fast, stable, and secure charging of custom 72V (20S Li-ion) batteries. ⚠️ Not compatible with stock (60V) Sur-Ron Light Bee bikes.

When charging overnight and you're not in a hurry, you can charge slowly at 3A or 5A, and when you need to charge quickly, you can go up to 10A. This flexibility also helps preserve battery life in the long term by adapting the charging intensity.

Its integrated OLED screen displays the charged capacity, battery voltage, and selected current in real-time. Current adjustment is simple via a rotary knob, for intuitive and precise use.

🔒 Safety and Compatibility

This charger is designed for modified 72V batteries: it respects the voltage, temperature, and current thresholds recommended by specialized tuners. Custom 72V batteries generally have a BMS adapted to charging up to 20 - 50A and high-discharge 21700 or 18650 cells (Samsung 50E, LG M50LT, etc.), ensuring excellent charge acceptance.

The power adjustment allows you to alternate between slow charge (3A) and fast charge (10A), thus optimizing the overall durability of your battery.
