Revolutionizing Electric Two-Wheeler Power Systems
Electric motorcycles and scooters have become the most popular urban mobility tools worldwide. Thanks to their lightweight body, affordable price, small footprint, and outstanding flexibility, two-wheeled electric vehicles perfectly solve short-distance commuting pain points. More importantly, on rugged mountain roads, bumpy rural routes, and congested urban streets where four-wheel vehicles struggle to pass, electric two-wheelers deliver far better accessibility and practicability.
As the core protection component of electric two-wheeler lithium battery packs, a high-quality electric motorcycle Bms (Battery Management System) directly determines vehicle power stability, riding safety, and battery service life. For over a decade, XJBMS has been fully specialized in two-wheeler BMS R&D and manufacturing. With more than 10 years of industry experience, we focus 100% on electric motorcycle and e-scooter bms solutions, accumulating over a thousand mature models to cover global two-wheeler market demands.
3 Main Categories of Our Electric Motorcycle BMS
We classify our two-wheeler BMS into three core series to match different cost budgets, power demands, and intelligent upgrade needs: bare board BMS, hardware BMS, and smart Bluetooth BMS. From basic cost-effective versions to high-end intelligent multi-function models, we provide one-stop battery protection solutions for all electric two-wheelers.
Bare PCBA BMS
Slim and lightweight, designed for direct battery mounting, and highly cost-effective. Best suited for standard civilian electric scooters and low-power commuter two-wheelers.
Range: 7S–13S string range, 10A–35A current range.
Hardware-based BMS
Equipped with professional aluminum heat sinks for superior thermal performance. Supports high current applications and complex road conditions.
Range: 4S–24S string range, 10A–300A current range.
Smart Bluetooth BMS
Equipped with advanced wireless transceivers, supporting LCD screen display, mobile APP monitoring, and host computer data viewing. Features multiple reserved interfaces.
Range: 4S–24S string range, 30A–250A current range.
Bare Board BMS Series
Our bare board BMS features an ultra-thin and lightweight design, which can be closely attached to the battery cells to save internal battery box space. With ultra-low pricing and high cost performance, this series adopts a fixed string design (single model for fixed string count). It is the best choice for daily urban commuting.
