25.9V Lithium Battery System Architecture
25.9V lithium battery packs typically utilize a 7S series cell configuration, forming a high-voltage lithium battery system.
As the number of series-connected cells increases, system architecture and management strategies become more critical. The battery management system (BMS) must continuously monitor key lithium battery parameters such as voltage, current, and temperature to ensure safe operation.
In high-voltage lithium battery applications, advanced system design—including balancing strategy, protection logic, insulation design, and thermal management—is essential to maintain long-term stability and operational safety.
With optimized system architecture, 25.9V rechargeable lithium battery packs can reliably support industrial equipment and professional power systems requiring higher voltage platforms.
