BMS and balancers


Need a battery management device? No problem! In our range you will find active balancers that effectively balance the voltage between individual battery cells and regulate the energy transfer between them. In this category you will also find BMS designed to monitor and control the charging, discharging and balancing processes of batteries, protecting them from damage and allowing communication with the user regarding the status of individual batteries in different modes of operation. BMSs designed for LiFePO4 and Li-Ion cells are available to optimise their management and provide safety features. We offer Smart BMS with integrated Bluetooth communication and BMS with support for CAN or RS485 communication. The category also includes monitors for detailed monitoring of battery status and a wide range of accessories to optimize and extend BMS functionalities.


Using a battery without a BMS will result in battery damage. These products will help you optimize the performance, life and safety of your batteries. Explore our range of BMS and balancers!
