Active
10S/20A (42V) Smart BMS for E-Cycle
The intelligence that keeps your e-cycle battery safe, balanced, and efficient.
Key Features
- Comprehensive Cell Monitoring: Continuously monitors cell voltage, temperature, and battery health to ensure safe and efficient battery operation.
- Advanced Protection Mechanisms: Provides overvoltage, undervoltage, overcurrent, thermal, and short-circuit protection to safeguard the battery and user.
- Smart Cell Balancing & Communication: Maintains balanced charging/discharging across all cells while enabling communication with motor controller, display, or mobile apps via interfaces like UART, CAN, or Bluetooth.
