The Heart of Light Electric Mobility
As the global transition toward sustainable urban transportation accelerates, Light Electric Vehicles (LEVs) like e-scooters, electric bicycles, and power-assisted vehicles have become the backbone of modern micro-mobility. At the core of every reliable LEV is a sophisticated Battery Management System (BMS). Our specialized BMS solutions are engineered to handle the rigorous demands of daily commuting, providing unmatched safety, efficiency, and longevity for your battery packs.
Optimized Voltage Range
Specifically designed for 10S to 20S configurations, supporting system voltages from 36V to 72V. Perfect for standard and high-performance LEV applications.
Multi-Chemistry Support
Whether you are using LiFePO4 (LFP) for safety, NMC for energy density, or the latest Sodium-ion (SIB) technology, our BMS provides tailored protection profiles.
Advanced Protection
Equipped with NTC temperature monitoring, passive balancing, and weak current switches to ensure the battery operates within its safest parameters at all times.
Technical Excellence & Specifications
Why 10S-20S Matters?
Light electric vehicles typically operate on 36V, 48V, 60V, or 72V platforms. Our BMS covers the entire spectrum:
- ✅ 10S (36V): Ideal for lightweight e-bikes and entry-level scooters.
- ✅ 13S-14S (48V): The industry standard for commuter scooters and delivery bikes.
- ✅ 16S-20S (60V-72V): Engineered for high-speed electric motorcycles and heavy-duty tricycles.
Current Handling (15A - 50A)
The working current is the lifeblood of LEV performance. Our BMS supports a continuous working current of 15A to 50A, accommodating both efficient city cruising and high-torque hill climbing. With peak current thresholds designed to handle motor start-up surges, we prevent nuisance tripping while maintaining absolute safety.
Smart Features for Smarter Mobility
NTC Temperature Protection
Heat is the enemy of battery life. Our BMS utilizes high-precision NTC thermistors to monitor cell and MOSFET temperatures, automatically throttling or cutting power to prevent thermal runaway.
Passive Balancing Technology
Maintain cell consistency effortlessly. Our passive balancing circuit ensures that every cell in your 10S-20S pack stays at the same voltage level, maximizing usable capacity and extending the pack's lifespan.
Weak Current Switch
Safety meets convenience. The integrated weak current switch allows users to turn the battery output on or off without needing massive, expensive high-current breakers, reducing standby drain.
Split/Common Port
Common port BMS shares terminals for charging and discharging.
Split port separates charge and discharge ports for lower heat and high-power stability.Smart/Normal BMS
Smart BMS supports Bluetooth monitoring and parameter adjustment.
Regular BMS provides basic over-charge, over-discharge, over-current, short-circuit protection protection.OEM/ODM & Factory Direct
As a dedicated BMS factory, we offer full customization. From specific PCB dimensions to communication protocols (Bluetooth, RS485, CAN), we build the BMS that fits your unique LEV design.
