Brainpower manufactures specialized motor controllers and LCD display units for electric bicycles and scooters, popular in DIY e-bike conversion kits.
Brainpower is a manufacturer of electronic control components for personal electric vehicles, specifically known for their brushless motor controllers and digital display interfaces used in electric bicycles (e-bikes) and electric scooters. The brand's product lineup includes versatile controllers compatible with 36V and 48V systems, offering wattages ranging from 350W to 1000W and beyond.
Commonly found in aftermarket conversion kits and replacement parts, Brainpower controllers are frequently paired with LCD dashboards such as the S866 and S886 models. These systems allow riders to monitor speed, battery life, and assist levels while managing motor output. While Brainpower components are widely distributed through global marketplaces like AliExpress and Amazon, the brand is best known among hobbyists and repair technicians for providing cost-effective solutions for e-mobility drivetrain management.

Common questions about manuals, registration, and support for this brand.
Standard Brainpower controllers typically use a 5-wire or 6-wire connector for Hall sensors. Match the wire colors (usually Red, Black, Yellow, Green, Blue) to your motor's Hall sensor output. If the motor runs efficiently, the phase angle is correct; if it stutters, you may need to swap phase wires.
Common error codes for the S866 display include E07 (Motor failure), E08 (Throttle failure), E09 (Controller failure), and E10 (Communication reception failure). Consult the specific manual for your controller model for a full diagnostic list.
Many Brainpower controllers are dual-mode, supporting both 36V and 48V inputs. However, you must check the label on your specific unit to ensure it rates for 48V usage before connecting a higher voltage battery.
